Proper operational temperature increases the service life of components (IGBTs, capacitors, boards, etc.)and therefore the reliability of the system and the efficiency of the inverters during the hottest periods,maintaining the power components (IGBTs) at a constant temperature.

Air-cooling uses industrial air conditioners with a “Free Cooling” function.

> Pure Free Cooling: with low external air temperature the conditioner acts like a normal ventilation systemwith external air exchange. The compressor is turned off.

> Assisted Free Cooling: with relatively low external air temperature the free cooling operates yet if it is notlow enough to keep the internal temperature at the required value, the compressor comes on as requiredby the temperature.

> Cooling: the compressor is running. The system acts like a regular air conditioner.

The “Free Cooling”, function, by modulating the use of the compressor, ensures reduced power consumptionfor enclosure cooling. Full power application occurs only when outside temperatures are very high.

To ensure the continuos operation, the overall cooling power for the enclosure is oversized: the systemoperates even if one of the air conditioners is out of service.

The free coolers, compared to regular ventilator fans, eliminate dust and reduce the level of humidity in theair, being potential causes of electronic equipment malfunction.

AnswerDrives has also certified the Solargate 5000 for use with water-cooling.

This cooling method improves dissipation.

The water-cooled enclosure, compared to the air-cooled version, is smaller and easier to maintain (thereare no filters to change and no liquids to top up).

An integrated water/water cooling control unit is available upon request for combined heat and powersystems.

24

>> “MIRO” FUNCTION <<

The “MIRO” Function

The “MIRO” function significantly increases the efficiency of the system, in particular under conditions ofpartial insolation of the array and/or under poor weather conditions.

In fact, the “MIRO” enables the conversion units to be activated/deactivated according to the power to besupplied with the objective of maintaining active only the units necessary for conversion of the electricitycoming from the PV array.

Thanks to the modularity of our approach, the conversion efficiency may be optimized by activating just theminimum number of units required for the supply of the power coming from the PV strings in large systems.

In this manner, the active conversion units will work within their most efficient operational range.

The graph illustrates the increased efficiency obtainable with the “MIRO” function.

The “MIRO” function with a Master-Slave rotation system balances the operation time of all units over thelong term, reducing wear and downtimes and prolonging the inverter's life cycle.

ARTICS Smart Energy

> > A R T I C S < <

29

>> Control at your fingertips <<

ARTICS Smart Energy is the control platform by Ansaldo Sistemi Industriali for the intelligent managementof low/medium voltage micro-networks capable of integrating traditional residential and industrial loadswith the production of renewable energy managing variability without compromising the quality of service.

The mode of operation known as “grid-connected” (the micro-network is connected to the distribution gridat a single connection point) and “island” (the micro-network is disconnected from the main grid) not onlyrequire their own independent monitoring and control system, but also a power supply system created withsmart devices, above all the inverters that input the power to the grid.

To be used within a micro-network, the inverters shall satisfy the following prerequisites, they must:> not produce EM interference that interfere with the network, especially when there are many inverters

connected> contribute to the frequency and voltage stability of the network, managing the active and reactive power

produced depending on the load requirements> maintain service even in the presence of strong network disturbances> be equipped with a communications system suitable both for the transfer of the data required for

network control to a higher-level control system in order to receive the proper commands

30

> > A R T I C S < <

Making use of the experience of the parent company, Ansaldo Sistemi Industriali, Answer Drives has madeits inverters smart by including advanced functions necessary for their application within the ARTICS SmartEnergy active energy management platform.

The system includes the following features:

Power limitation in conformity with the law EEG §6 on renewableenergy and grid safety managementTo avoid short term overloads on the grid it is possible to establish themaximum amount of power the inverter will input into the grid by settinga parameter. The maximum amount, variable from 0 to 100%, isdefined by the utility provider and is transmitted to the inverter by wayof serial port.

Active power regulation according to the frequencyThe inverter automatically reduces the active power input in the event ofan increase in frequency over the established value by a parameter witha ΔP% / Hz gradient of the power available. The active power may beincreased again only if the frequency value returns below theparameter. The power gradient is set with a parameter. This functioncontributes to the stabilization of the grid frequency.

Grid support by way of reactive powerTo keep the mains voltage constant, inverters provide inductive or capacitive reactive power to the grid.Three variations may occur:

a) Fixed value for reactive power*.The utility provider defines the fixed value, set by way of a parameter, for reactive power. If the reactivepower is positive then it is of the inductive type, and when vice versa it is capacitive. Some utility providersrequire the reference value to be set at tanΦ. The tanΦ, value set by way of serial, is defined with aparameter in the -0.484 to +0.484 range corresponding to cosΦ = -0.9 to +0.9.b) Setpoint variable of reactive power according to the grid voltage VgridThe input of reactive power according to the network voltage is used to compensate the slow voltagevariations at the point of connection of the power plant to the grid.

* The reactive power value required must be taken into consideration when sizing the inverters.

Reactive power is managed according to three parameters:

> The parameter that defines the minimum voltage variation required,causing a reactive power variation.> The parameter that establishes the reactive power variation caused by

a grid voltage variation during operation with active power at anominal level; the reactive power variation is implemented after atime that may be set.> The parameter that sets the minimum time that the voltage variation

must last to require that the correspondent reactive power variation beactivated.

Dynamic voltage control (FRT)The dynamic network support, is the control set out to ensure gridstability in case of sudden drops in voltage. This type of control is oftenindicated as Fault Ride Through.

Power plants that sustain the grid must, in case of a voltage drop, avoidunintentional disconnection so as not to cause a collapse of the grid.Reactive power input into the grid must also contribute to its support.After recovery from a malfunction, reactive power input must not begreater than the input before the fault.

ARTICS Smart Energy responds to the requisites set by MV directives and by the BDEW directive.

The string box enables the connection of several strings in parallel.

The current from each string is measured by way of a transducer and any faults are immediately detectedby the monitoring system with fast identification of any problem in the panels.

Each box has overvoltage protection installed to protect the inverter from overvoltage peaks.

The output DC switch facilitates maintenance operations on the section with the system still running inperfect safety.

Thanks to the double insulation and the IP65 protection rating, the box ensures the highest level ofprotection both for the operator and for the internal equipment.

For rooftop installation, generally the authorities require that the string box be equipped with an output DCswitch with a remote trip so as to respond to heightened safety requirements.

This string box may be supplied with a DC switch equipped with a minimum voltage coil to separate thePV generator from the inverter (Options are to be requested during the order).

> System for monitoring andidentifying any faults in the strings.

> Input peak overvoltage inverterprotection.

> Fuses on the positive and negativepoles.

A static meter with LV connection is foreseen for measurement of subsidized electricity.

The meter may be mounted onto the Solargate 5000 cabinet or in a separate box.

The meter is to be checked and certified with a cumulative certification +CT and VT including tax duty.

Supplied standard are: UTF, CT e VT proof terminal block for BT Cl 0.5 (with UTF certificate), GSMMODEM power supply, stylus antenna, terminal board and wiring for connection to meter.

The meter, besides in situ reading, can acquire the impulses from one or more meters.

In systems with LV/MV transformers with two secondaries, two meters are required, one of which will bethe master acquiring the reading of the second so as to provide a single electricity reading.

The Weather Station

57

The weather station is ideal for users who give great importance to the total analysis of performance evenon the PV power generation side.

Weather conditions influence PV electricity production to a great degree, yet this does not mean thatefficiency cannot be optimized.

The Answer Drives weather station uses a multi-function sensor, which, besides module insolation andtemperature data, also manages an ambient temperature sensor and an anemometer for the purpose ofmaking even more precise calculations on the operation of the PV system.

The data gathered by the station enable the calculation of the nominal power provided by the currentinsolation and by the module temperatures and the comparison of this with the actual power measured bythe inverters. Significant downward shifts signal faulty system operation.

In this manner shaded areas, dirty panels and hard to find power reductions — due, for example, to thedegradation of one of the panels — can be identified.

The sensor output is in RS485 with the Modbusprotocol, particularly indicated in applicationswhere the sensors are far from the data logger.Just make the simple connection of the station,by way of the Data Logger serial port, whichwill then transmit the data received to a PC orto an Internet site for further processing.

For users with less weighty needs, the stationmay be provided in a basic version that willmeasure the insolation, ambient temperatureand module temperatures.
