6BSAGS, SWELLS AND INTERRUPTIONS



3. SAGS, SWELLS AND INTERRUPTIONS The analysis fulfils the IEC 61000-4-30 standards for the sag, swell and interruption analyses and results.

3.1 SAGS AND SWELLS The PQM register analyses the sags and swells of the simple and/or compound voltages, classifying them in 2-input tables and event chronological lists (detailed and summary). The parameters defining these analyses are the depth of the sag or swell and the time this event lasts.

The depth is calculated according to rated voltage:

100%Un

UhsUnDepth = (3.1 equation)

where:

Un simple and/or compound nominal voltage (setting)

Uhs phase maximum simple and/or compound voltage in situation of sag or swell. The analysis is carried out independently for each channel. The refreshed measurement of a cycle is used every half cycle, so that we have an updated measurement every half cycle.

Sag is considered to occur when the sag threshold is exceeded in any of the three simple and/or compound voltages, depending on the selected unit. The sag is considered to be over, when none of the three voltages is in situation of gap (exceeding in the hysteresis the setting threshold). The duration is considered from the very moment the first channel enters the sag until all of them return to normality. The sag width is the highest depth (minimum voltage) of all the channels in swell.

Swell is considered to occur when the swell threshold is exceeded in any of the three simple and/or compound voltages, depending on the unit wiring procedure. The overvoltage is considered to be over when none of the three voltages is already in overvoltage situation (exceeding in the hysteresis the setting threshold). The swell duration is considered to be from the very moment the first channel enters in swell until all of them return to normality. The swell width is the highest depth (maximum voltage) of all the channels in swell.

In the event summary queue, the sags and swells are stored, grouped according to the criteria previously described. The data of each phase is located in the event queue in an individual way.

The measurement precision is 0.2% of the nominal voltage. The duration precision is cycle of the signal at the beginning plus another cycle at the end.

The hysteresis can be programmed. For example for a 2% hysteresis, if sag is considered to be a drop higher than the 10%, the voltage measured must be over the 8%, in order to consider it has recovered.

The parameters used for the gap and swell detection are the following ones:

Sag threshold. Minimum variation respecting to the nominal voltage to consider sag.

Sag hysteresis. Minimum variation to recover from the sag.

Swell threshold. Minimum variation respecting to the nominal voltage to consider swell.

Swell hysteresis. Minimum variation to recover from the swell.

Minimum separation between events in order to be considered the same event or a new one. There are also other parameters, used for signalling sags and swells which are those below:

Sensitivity for sag. Variation to consider the new step inside the sag (increase and decrease events).




Sensitivity for swell. Variation to consider the new step inside the swell (increase and decrease events).

Maximum number of notes per event. It restricts the number of notes registered in each sag and swell. It only affects to those of increase and decrease notes.

Sag maximum time . Maximum time since the sag start, during which the sag pulse signal is kept active. Once this time is elapsed, the pulse signal is deactivated, although the sag continues and no more notes are done in that sag. If the time is set to 0, it is the same as if this option would be deactivated, so the sag end is not restricted in a time and the sag pulse signal coincides with the sag one.

Swell maximum time. Maximum time since the swell start, during which the swell pulse signal is kept active. Once this time is elapsed, the pulse signal is deactivated, although the swell continues and no more notes are done in that swell. If the time is set to 0, it is the same as if this option would be deactivated, so the sag end is not restricted in a time and the sag pulse signal coincides with the one of the sag.

For example, having the nominal voltage set to 80V, if considering a sag starts from 72V on, the sag threshold must be set in 10%. It is deduced from 3.1 equation:

10080

7280%_ =thresholdSag

In the same way, if considering the swell starts from 88V on, the swell threshold must be set in 10%.

Figure 6. Event summary

3.1.2 Event chronological noting The event representation is done through the chronological annotation and through their phases (simple and/or compound). For simple voltages, the channel is defined through Va, Vb or Vc; meanwhile for the compound ones by Vab, Vbc, Vca.

It has a queue with 16000 annotations. The number of events stored depends on the annotation done for each of them. By setting, the maximum number of annotations by each events can be limited. These data can be accessed from the Register menu with the option Bring events or from the tool bar with the Event button.

Together with this annotation, it is shown a graphic with the voltage wave shape during the event. This graphic detail depends on the annotations taken for every event. The graphic has the autoscalar, manual scalar and zoom properties.

Every event will dispose the following annotations

Normal before: It is characterised with a N and it has the dated value of the depth and the phase primary voltage 200msec before the considered event happens.

Sag or swell: It is characterised with a L (sag) or a H (swell), and it has the dated value of the depth and the phase primary voltage in the very moment the event beginning is detected.

Back to normal: It is characterised with a V it has the dated value of the depth and the phase primary voltage in the very moment the event end is detected.

Normal After: It is characterised with a n and it has the dated value of the depth and the phase primary voltage 200 msec after the considered event finishes.

Increase: It is characterised with a I and it has the dated value of the depth and the phase primary voltage while the event lasts. It refers to the increases of the voltage value, and so to a reduction of the event depth.

Decrease: It is characterised with a D and it has the dated value of the depth and the phase primary voltage while the event lasts. It refers to the decrease of the voltage value, and so to a un increase of the event depth.

Overvoltage maximum: It is characterised with a M and it has the overvoltage maximum value reaches and the data in which it has occurred.




Sag minimum: It is characterised with a m and it has the sag minimum value reached and the data in which it has occurred.

Sag/swell average: It is characterised with a A and it has the voltage average value during the sag or swell. The data corresponds to the average data between the beginning and end of the events.

Sag/swell pulse time expired: It is characterised with a E. In case the pulse duration maximum time is configured, it occurs when the time since the sag or swell starts is elapsed.

Summary: It has the depth maximum values, the corresponding primary voltage and the duration of this event.

Figure 7. Event representation

As it is shown in Figure 7, the event list offers information about the following:

The type of event (sag: LOW; swell: HIGH).

Channel in which the event has occurred.

Event duration.

Event evolution graphic according to the annotations. If the event number is high and all of them are desired to have automatically unfolded, inside the Relay menu , of the main menu bar, there is the option Unfold all; the opposite can also occur, that is Compact all.

3.1.3 Depth-duration tables Independent depth-duration double input tables for sags and swells. The table has a one-year duration. The register can store 15 sag tables and 15 swell tables. These data can be accessed from the Register menu with the option Bring tables.

A table is considered to be finished and a new one is started in the following examples:

Changes in the table settings.




Users order (command)

A year has elapsed since it started. In order the register to start treating a sag or an overvoltage with the aim of storing in the corresponding position in the table, the sag or overvoltage threshold must have been exceeded in depth. When none of the three phases is already in event situation (exceeding the set threshold in the hysteresis) the unit measures its time. This time comprises from the moment the first phase enters the event until the last of the faults leaves the event. This time is noted in the cell defined by that duration and by the maximum depth given during the time in which the event has existed.

These tables allow seeing, in a global way, the data collected in the Event Summaries queue.

4.1 OVERCURRENT Overcurrent function carried out over the current protection transformer (20In background scale). The settings used by this function are the following ones:

Enable

Overcurrent threshold. It is set in secondary amperes.

Additional time

Baud rate 5A Setting Min. Max. Step Notes Enable YES/NO Overcurrent threshold (A) 0.1 100 0.1 A Additional time (sec) 0 100 0.1 Seconds

Baud rate 1A Setting Min. Max. Step Notes Enable YES/NO Overcurrent threshold (A) 0.01 20 0.01 A Additional time (sec) 0 100 0.1 Seconds

The analysis is carried out over the three current protection phases.

Being this function enabled (setting), when the measured current value excesses the threshold (setting) during the additional time (setting), the signalling is generated and it indicates that an Overcurrent has occurred. Once it is activated, the current value must drop under the 95% of the setting, on order to deactivate it.

The overcurrent activation generates control digital signals and it acts over the programmed digital outputs.

The events generated are the following ones:

Overcurrent pick up: Date, phase and current value

Overcurrent activation: Date, phase and current value

Maximum overcurrent: Date, phase and current value

Overcurrent end: Date, phase and current value

Overcurrent duration: Fault duration summary

4.2 THD OVEREXCITATION It checks the harmonic percentage regarding the fundamental one, over the current measurement transformer (1.5In background scale) and over the voltage transformer. The analysis is carried out over the three phases. The settings used by this function are the following ones:

Enable

THD current threshold. Set in %.

THD voltage threshold. Set in %.

THD maximum time Setting Min. Max. Step Notes Enable YES/NO THD I threshold 1 100 0.1 % THD V threshold 1 100 0.1 % THD maximum time (sec) 0 100 0.1 Seconds

Being this function enabled (setting), when the measured THD value excesses the threshold (setting), the signalling is generated and it indicates that an overexcitation has occurred. Once it is activated, the THD value must drop under the 95% of the setting, on order to deactivate it.

The maximum time THD indicates the time from the starting of the THD, during which the THD pulse signal remains active; when this time ends, the pulse signal is deactivated although the THD keeps on. If the time is set to 0, it is the same as having the option disabled, so that the THD is not limit in a time and the THD pulse signal matches with the THD signal.

The THD overexcitation activation generates control digital signals and it acts over the programmed digital outputs.

The events generated are the following ones:

THD activation: Date and phase

These data are stored in the PC where they are accumulated to the data previously captured, so data corresponding to a long period are available. These data are presented as a list and in a graphic format, allowing different analysis types to be carried out on them in the PC without being connected to the register.

The historical carried out are the following ones:

Voltage and current historical.

Power historical

Harmonic historical The different historical can be individually enabled, selected which measurements are going to be sent and its integration period.

The total number of measurement stored is fixed, so depending on the storage period and the number of measurement selected the time will be longer or shorter.

At least, the historical values corresponding to a month, taken every hour, are stored; that is, 744 registers. If changing the sampling period, the total time stored also changes.

When the historical configuration is changed, those previously stored in the register are lost, so if they are desired to be kept, before changing the configuration, they have to be requested and stored in the PC.

Each historical can be deleted via command:

Delete V-I historical. Command 111

Delete power historical. Command 112

Delete harmonic historical. Command 113 The historical are also deleted when deleting all the memory (command 110), which deletes not only the historical, but also all the data stored in the memory.

The historical display can be carried out as a list, where the data and the value are indicated (Figure 9), or in a graphic way, where apart from the time evolution, each point value can be seen (Figure 10). This representation is valid for the different historical types.

The access to the historical is from Register menu with the option Bring historical or from the tool bar with the Historical pushbutton. The available data are the following:

5.2.2 Statistical The storage of statistical data (maximum, minimum and mean), calculated within a determined periodicity is carried out in a circular queue. Both the measurements and the storage periodicity can be programmed by the user. Additionally, the statistical are calculated with a 1-day, 1-week, 1-month and 1-year periodicity that cannot be programmed by the user.

These data are stored in the PC where they are accumulated to the data previously captured, so data corresponding to a long period are available. These data are presented as a list, where the date and the registered values are indicated ( Figure 13), allowing these data analysis in the PC without being connected to the register.

The statisticals to be calculated are the following ones:

Voltage and current statisticals.

Power statisticals

Harmonic statisticals The statisticals can be individually enabled, the measurements to be sent and the integration period can be selected.

The following statistical data will be stored in the register:

annual: 1 register

monthly 12 registers (1 year)

weekly: 54 registers (1 year)

daily: 31 days (1 month)

time schedule: 744 registers are stored, corresponding to the values of one month taken every hour. If changing the sampling period, the total time stored also changes.

When the statistical configuration is changed, those previously stored in the register are lost, so if they are desired to be kept, before changing the configuration, they have to be requested and stored in the PC.

The access to the historical is from Register menu with the option Bring historical or from the tool bar with the statistical pushbutton.

Each statistical can be deleted via command:

Delete V-I statistical Command 114

Delete power statistical. Command 115

Delete harmonic statistical. Command 116 The statisticals are also deleted when deleting all the memory (command 110), which deletes not only the statistical, but also all the data stored in the memory.

5.3 OSCILLOGRAPH DATA RECORDING The oscillograph data recorder can be programmed between the following possibilities:

Perturbations Cycles 10 60 20 30 40 15 60 10 120 5

The number of selected cycle is stored in each oscillo, being 32 the number of samples per analogue channel cycle.

The number of cycles previous the pick up is programmable. In each oscillo, up to 8 analogue channels can be registered and also up to 32 digital channels selectable from a list selected among the available signals.

The oscillo starts by a rising slope of any of the digital signals contemplated in the register.

The analogue channels are sent to the console multiplied by the transformation ratio in order to appear in primary values.

When the oscillograph configuration (number of cycles) is changed, those, previously stored in the register are lost, so if they are desired to be kept, they have to be requested and stored in the PC, before changing the configuration.

The oscillograph stored in the memory can be deleted when resetting the queue The deleting can be individual (only oscillographs) or global (all the memory).

The access to these data is from Register menu with the option Bring wave shape or from the tool bar with the Wave shape pushbutton.

6. REGISTER CONFIGURATION

6.1 TIME SETTING AND SYNCHRONIZATION

6.1.1 Time setting It can be carried through the Protection Console with the synchronization pushbutton.

6.1.2 Synchronization There is an input for synchronization via IRIG-B demodulated. (See section IRIG-B Input inside Technical characteristics).

The time code IRIG-B is a mesh generated once a second. The code used is B 003, in which the mesh is constituted by a pulse train with TTL of variable widths. The time shown corresponds to the PPS (pulse per second) coinciding with the Mesh Reference Mark of the beginning of the mesh. There are two options.

Format B002: The year is not sent in the message.

Format B002 with IEEE 1344: The year is sent in the message. In Integrated Control Systems (SIPC) the register is periodically synchronised (every minute) by the UCS.

In this case, it is useless to change the time in the Protection Console, because it will be deleted by the UCS.

Once activated the outputs are kept at least 50 ms.

6.3 PROGRAMMING LEDS The procedures are totally similar to those of the digital outputs, with the exception that the activation time is not programmed.

6.4 PROGRAMMING LOGIC OUTPUTS The user can configure up to 15 logic outputs, called logic 1 to logic 15, which can be assigned to relays, as web as to LEDs, locking inputs, signals to be registered on the disturbance recorder, etc.

The programming of the logic outputs can be only done through the Protections console, from the basic available signals, consigned in the Table 4 (only the functions that the model contains correspond. to each model). The programming procedure is described in other document: the Protections console manual.

The logic signals are generated according to the following scheme:

As it can be observed in the definition of a logic output the following elements are involved:

Up to 16 signals among the available ones (or their negated ones), forming an OR function

Up to 16 signals among the available ones (or their negated ones), forming an AND function

an OR or AND function (programmable) of two previous functions results

a programmable time delay ("delay") to activate the output




a programmable time for the duration of the output activation The delay time is the time length since there is a logic 1 at the output of the logic ports until the corresponding logic output is activated. If during this time the 1 disappeared, the output could not be activated. It can be programmed between 0 and 99.9 s, with steps of 0.1 s.

The pulse time (duration) is the time during which the logic signal remains active. Its programming allows two options:

"By logic": after the delay, the output is active as long as there is a 1 at the programmed logic output

"By time": the time during which the output is active is programmed, so that once expired the output is deactivated, independently from the state of the programmed logic output. Only a new step from 0 to 1 will activate the output again, after the delay. The time range goes from 0.1 s to 99.9 s, with steps of 0.1 s.

A logic output "i" can be used as available signal for programming input of other logic signal "j" or of itself.

0BKEYBOARD / DISPLAY



APPENDIX I. KEYBOARD / DISPLAY It may optionally dispose of a display (2 lines and 16 characters) and a keyboard with 16 keys.

The keyboard/display units aim is displaying the states of the digital inputs, measurements and date. The display language can be configured and the date can be changed.

On standby, the display shows PQM300-T and the software version it has.

At any moment of the procedure described below, by pushing ESCAPE the unit moves to the menu element of the immediately previous level.

The menus are scrolled downwards or upwards with the pushbuttons and , and they are circular, that is, after the last position it goes to the first one again.

In general terms, when a menu is scrolled, the first line of the display indicates the active function, which can be entered by pushing INTRO. That way, we enter the following menu level (if there was) specific for that function.

The menu tree to display or change settings inside a each group is hierarchical. If on standby (title), we push INTRO, we reach the following menu:

SEE TIME

MEASUREMENTS

SEE SETPOINTS

CHANGE SETPOINTS

I.1. USE OF THE KEYBOARD/DISPLAY

I.1.1 See settings and magnitudes With the keys and it is possible to move around each menu or submenu (indicated in the previous section) upwards or downwards, since the menu are circular.

By pushing INTRO the following menu level is reached. If it did not have a submenu it would not change its state when pushing INTRO.

By pushing ESC the element of the previous menu is reached, that is, the one from which can reach the present status..

In the final menus, those with no submenus (settings), the name of the setting group, selected by means of keyboard, appear on the first row, and on the second row its present value.

I.1.2 Change settings Up to the last level of the menus everything works in the same way as in See settings and magnitudes (same functions for same keys).

To access to this function, it is necessary to press the key "". Through this all settings and initializations are made accessible, except the ones contained in the section "Define protection. To access these the key "" is necessary

In the last level of the menus, where the name of the settings we want to change appear, the keyboard operation is different from the one we have explained until now.




When entering into each group to change the settings, which are included (final menu), the keyboard operation will be as it follows:

1) Numerical settings. The first line of the display shows the name of the selected setting followed by its current value. The line 2 shows the text NEW followed by the current setting range, which can be changed by using the numerical keyboard.

To change the setting range we use the numerical keyboard. The new range has to be literally entered, this means that if we wish to enter the new value of 23 the key 2 will have to be pressed, and followed by the key 3. If the value is not valid, when pushing INTRO to access to the next setting, a warning message will be shown on the line 2 indicating INVALID VALUE. A valid value will have to be entered to be able to access the next setting within the group, by pressing INTRO. The pressing of ESC within the final menu takes us to the menu element, which we came from, without making effective the changes we have made until the moment of pressing.

The changes are made effective when at the moment of reaching the last group setting and pressing INTRO, we receive the message VALIDATE SETTINGS and press INTRO to validate the changes; if we validate them by pressing INTRO, we would return to the next element of the menu above (see menus chart). By pressing ESC we return to the menu element from which we reached the actual state.

2) Non numerical settings. There are settings, such as language, that offer some possibilities to choose, because it is clearer to selct them by their name instead of entering its numerical value.

Whenever possible and clear, on the line 1 the name of the setting will appear along with a text indicating the actual value. On the second line it will gradually appear the possible values to choose for this setting, if we use the keyboard properly. We use the key to go through the different possibilities we have on each state. In the case of inputs, outputs or leds configuration we can use the keys and to select the configuration of each of them; we do it this way because there are many configurations to choose from and this makes it quicker.

As for the numerical settings, by pushing INTRO, we move to the following setting until reaching the last one of the group, in which we have to valuate by pushing INTRO. The pressing of ESC takes us to the menu element from which we reach the actual status.

I.2. MENU Below, we enclose a table which graphically illustrates and shows the easy handling of the different menus and settings which can be changed with the keyboard/display. We recommend this appendix be at hand when you start to use the keyboard, in order to easily find the settings to be changed.

1BRECEPTION, STORAGE, INSTALLATION AND TESTING



APPENDIX II. RECEPTION, STORAGE, INSTALLATION AND TESTING

II.1. RECEPTION AND STORAGE The register protections are supplied in special packing material for transport.

Upon reception, they should be checked for any signs of external damage caused during transport; if so the transport firm and manufacturer should be contacted.

The material received should also be checked to see if it coincides with the order number.

If the register is not going to be used immediately, it should be stored in its original packaging and in a dry and dirt free place.

The unit transport must be made in its original packaging.

II.2. WIRING PROCEDURE The register wiring procedure should be carried out in accordance with the enclosed external connection diagram. It is a general diagram; the programming of inputs and outputs should be taken into consideration in each specific case.

Power supply The polarity is indifferent.

Earth connection It is important for the earth connection to be correctly connected, in order for the protection disturbance rejection devices it incorporates to operate properly. The connection should be as short as possible (less than 25 cm.) using multiwired cable with a 4 mm

2 cross-section.

II.3. REGISTER ADDRESSING See Communications configuration section.

II.4. COMMISSIONING The PQM300 registers are received with the default settings stipulated by the factory.

Before commissioning they must be set, with the correct values for the application, following the setting procedures.

The register has been checked at the factory in order to guarantee its accuracy in all of the setting points of the different parameters. However, it is convenient to test some points during reception and commissioning, in order to ensure it is totally in proper operating condition.

Once the line is connected the real measurements, the relay is carrying out can be displayed, thus enabling you to check for proper connection and operation.

II.5. RECEPTION TESTS

II.5.1 Material needed

Triple-phase voltage and current generator unit with variable frequency of type




II.5.2 Measurement tests The measurement range is up to 1.5 times the nominal value (5 A). The error made in this range must be lower than the 0.5% of 1.2*nominal value

The worker decides the points to check but those below are recommended:

Current (A) Voltage (V) 0.5 20 1 50 5 (nominal) 65 (aprox. nominal) 6 80

The measurements will be carried out by injecting voltages and currents in a phase and checking in the console that that phase presents a value different to zero and that is within the defined margins.

This test must be carried out for all the phases seeing the measurement in the console.

II.5.3 Register time setting From the synchronization menu, time and date of the PC are introduced.

Push OK and check if the relay accepts the data/time sent.

2BPREVENTIVE MAINTENANCE



APPENDIX III. PREVENTIVE MAINTENANCE The self-checking the register carries out continuously can detect the following situations:

Failure in the voltage reference of the converter

Failure in the FLASH memory recording

Failure in the relay activation

Failure in the DSP communication

Failure in the clock synchronization

Battery failure In case of detecting any failure, the alarm is kept until the failure disappears. This alarm can be displayed through:

Control events

Events

Digital outputs

Led

III.1. FAILURE DETECTION The failure detection can happen in various ways.

Control signals If the hardware status signal (see signals 128 to 133 in the section List of Available signals) are set at 1, they indicate that anomalous situation is occurring in the register. With value at 0 it indicates Hardware OK.

Digital outputs A digital output can be programmed with the signal HW status, which will be activated in case of critical error and deactivated under normal operation.

Leds The programmable Leds dispose the same options as the digital outputs.

The bicolour Led programmed as (Failure HW) indicates:

Correct functioning, if green

Critical error detection, if red

Events The events indicate the type of error detected and they are those quoted in the first part of this chapter.

The event of corrected hardware errors indicates that the problems have been solved.

2BPREVENTIVE MAINTENANCE



III.2. ERROR HANDLING PROCEDURE The procedure will depend on the detected error and the register status and on the state of the register.

If the register is off, check that the power supply is correct. If the unit is well supplied, contact the technical service.

If the register is on but it shows failure, return to the events screen and check which type of error it is:

If critical error, with no specific indication, is shown and the error persists after turning the register off and on, contact the technical service.

If converter or reference voltage error is shown. Check the measurements, and if they are correct, turn off and on the register; if the error does not disappear, contact the technical service.

If Clock error is shown, synchronize it manually. If the error persists, contact the technical service.

If error in the Flash memory recording is shown, send the settings again. If the error persists, contact the technical service.

3BUSER INTERFACE



APPENDIX IV. USER INTERFACE The quality register can be monitorized through a PC. That way, both register data and its configuration can be easily accessed. It also allows the displaying of sag and swell stored to the event queue, to the quality historical as well as to the control measurements continuously carried out by the register and to the capture and displaying of the wave shape. Besides, it allows programming the necessary settings for its operation.

The communication with the register can be LOCAL mode (Null Modem cable) or REMOTE (telephone call via modem).

Two options of user interface are available:

PQM Console: it operates only with the quality registers.

Sipcon Console: it allows the operation inside an integrated control system, with other units such as protections .

IV.1. PQM CONSOLE This console operates in an autonomous way and allows the automatic control of several registers. It also allows LOCAL and REMOTE communication, as well as working without being connected to the register
