3 Using the Converter The ABB RED615 XRIO converter can be used as a stand-alone converter or in association with a relay specific test template. In any way the converter is used, follow the quick start instructions and create your test using LinkToXRIO or start using the relay specific test template (for more information, see the test template documentation). See sections 8.2 for more information about using the XRIO converter with the OMICRON Differential test module.

4 Required Software Version To use this converter, you must have a valid license for the OMICRON Test Universe 2.22 software.

5 Functional Range The ABB RED615 XRIO converter implements the following functions:

• LNDLPF: Differential protection for two line terminals (including inrush detection) • PHLPTOC, PHHPTOC, PHIPTOC: Definite time and timed overcurrent • NSPTOC: negative sequence overcurrent protection

All of these functions (except the PHIPTOC overcurrent protection) use the RIO Interface of the OMICRON Test Universe Software.

6 Not Supported Functions The following functions are currently not supported:

• INRPHAR: Transformer inrush detection for overcurrent and negative sequence overcurrent • CCBRBRF: Circuit breaker failure protection • CCRDIF: Current circuit supervision

7 OMICRON Test Strategy The OMICRON test strategy is described in the OMICRON Protection Test Template (PTT) Differential documentation. For detailed information, see the PTT Differential documentation.

8 Converter Structure The converter is divided into two sections: the RED615 section and the RIO section. Both sections consist of several function blocks. The converter comes up in the standard view; the RIOplus section and the template controller section can only be seen in the advanced view.

8.1 RED615 Section

The RED615 section is divided into four groups: the Local Relay Parameter Section, the Additional Information section, the RIO Plus section and the TemplateController section.

8.1.1 Relay Parameter Section

The Local Relay Parameter Section includes the parameters which have to be changed by the user. The parameters are grouped and named as in the PCM600 settings software.



Figure 2: Setting the parameters in the Relay Parameter section

8.1.2 Additional Information

This block holds some very important parameters that are used to define the general test strategy. Those parameters are found in the subblock Test Configuration. Here the Diff Test Mode can be selected and the number of the local relay, if a GPS test is done. The different Test Modes are explained in Figure 4 and in the ABB RED615 Template manual. If both relays shall be tested with one CMC an additional block appears: 2. Local Relay Parameter Section. Here the CT data of the second relay can be found. The rest of the additional information are mainly relay specific parameters such as tolerances or operating times which cannot be set by the user, because they are constant values. All values set in this block can be found in the chapter "Technical Data" of the relay's documentation. Typically, these blocks do not have to be changed.

Annotation: It is also possible to control both CMCs with only one PC. Therefore a second instance of the OCC Center has to be started. This can be done, by opening the second OCC-file with the start page entry "Open Existing Test Document". The CMC in the remote substation can be accessed via a network connection (Net-1 option only).

8.1.3 RIOPlus (Advanced view)

The RIOplus block contains the interface, which provides the link between the XRIO converter and all test modules which have no access to RIO functions. All tests using basic test modules like Ramping or State Sequencer have to be linked to the parameters in the RIOplus section of the converter.

8.1.3.1 Nameplate

The NamePlate block contains all necessary information to identify the protection device to be tested. This block contains the relay vendor, serial number, model, the relay location and a description.

8.1.3.2 PowerSystemParameters

This block contains information about the nominal frequency of the system and the phase rotation.

8.1.3.3 DifferentialProtection

This block contains all information needed for differential protection tests. This includes the differential characteristic and the harmonic restraint elements. The differential characteristic is constructed as shown in the RED615 relay manual. This block contains settings for both ends of the line. The upper part of Figure 5 shows the situation for the single relay test and the GPS test: In that case the settings from the local relay are taken to configure Leg 1 and Leg 2. This is done because by doing so no settings of the remote relay are needed and the effort of entering the settings to the XRIO Converter is minimized. If a GPS test is done, a second set of test equipment is needed at the 2. location and the missing settings of the other side will be stored there, as they are local relay settings there. This means, that the differential



protection block can be different on both sides. But the test will still work, as the used settings for testing will always be correct. If both relays shall be tested with one CMC, both relays are "local". The settings of the second local relay have to be entered in the additional information (lower part of Figure 5).

8.1.3.4 Overcurrent

This block contains all necessary data for testing the overcurrent and negative sequence protection of the local relay. The nominal values and CT settings used by this protection function can be found here. All stages of the overcurrent protection function in the relay are modeled as sub blocks of the overcurrent protection. The inrush detection for the overcurrent protection is not supported.

8.1.3.5 Circuit Breaker

The circuit breaker block contains all necessary data for testing protection functions together with the circuit breaker. The modeled parameters are 52abPercentage, CloseTime, Forced3PoleOperatingTime, and TripTime.

8.1.4 Template Controller (Advanced view)

The Template Controller block contains special values needed for some tests, especially for tests using LinkToXRIO. These are mainly calculated values which cannot be calculated using LinkToXRIO and therefore have to be stored in this section. Other values needed for customer designed test can be stored in this block.



8.2 RIO

The RIO section of the converter contains all specialized RIO functions needed to use the more specialized test modules (like Advanced Differential or Overcurrent) provided by the OMICRON Test Universe software. Warning: Do not change any values in this section. The values have been set using the relay settings of the Relay Parameter section. Note: Do not activate the former test object view in the advanced mode of the XRIO test object. Changing parameters in this view could disable formulas in the RIO section.

8.2.1 Differential

The RIO differential function provides the necessary values for testing the differential protection function of the RED615 relay. The RIO differential function contains all values needed for using the following OMICRON Test Universe modules:

• Diff configuration • Diff characteristic • Diff trip time (A IDMT characteristic is not supported here.) • Diff harmonic restraint

8.2.2 PhaseOvercurrent

This overcurrent RIO functions contains the overcurrent characteristics for the relays functions PHLPTOC1, PHHPTOC1 and PHHPTOC2. The 4th overcurrent protection function PHIPTOC1 is tested separately with the State Sequencer Module.

8.2.3 Negative Sequence

This overcurrent RIO functions contains all necessary data to test the negative sequence protection functions NSPTOC1 and NSPTOC2.

8.3 Specific Features

This section deals with special requirements of some of the converter's functions. Functions not listed here have no known limitations to their functionalities. The CT's amplitude correction factors are not supported.

8.3.1 Overcurrent and Negative Sequence

There can be only one active timed overcurrent (IDMT) stage at a time which must have the smallest pickup value of all active overcurrent stages. The same is true for the negative sequence protection. The converter doesn’t support the Operating curve type "RD type". The setting Minimum operate time for the IDMT stages is not taken in consideration to construct the overcurrent characteristics.
