Reactive Power ControllerDischarge timeThe discharge timemeans the time, whicheach capacitor stagehas got for discharge.Setting range : 0 - 1200 secondssProgThe discharge time will be started after a net return andafter switching of a capacitor stage.Capacitor stages controlled by transistor outputs mustnot consider the discharge time, as the therewith controlledsemiconductor switches in the zero crossing ofvoltage.Example: Programming discharge timeWith key 3 you can leaf to the discharge time in theexpanded programming. With key 1 you get into programmingmode. In this example a discharge time of60 seconds is indicated.Select the digit to bechanged using key 2.The selected digit issflashing.ProgChange digit using key3.Pressing key 1 you leave the programming mode andwith key 3 you can continue leafing through the expandedprogramming.Disconnection pauseThe disconnectionpause means the timeafter the connection ofa capacitor stage, inwhich it is forbidden todisconnect the next stage.Setting range : 0 - 1200 secondsThe disconnection pause is not valid for capacitor stages,switched via transistor outputs.Example: Programming of disconnection pauseWith key 3 you leaf to the disconnection pause in expandedprogramming. Please press key 1. In this examplea disconnection pause of 15 seconds is indicated.Select the digit to be changed by using key 2. Theselected digit is flashing.Change the selecteddigit using key 3.sProgsProgPressing key 1 you leave the programming mode andwith key 3 you can continue leafing through the expandedprogramming.Page 26= Key 1 = Key 2 = Key 3
Reactive Power ControllerPower station serviceBy setting "power stationservice" the reactionof the controller atsmall currents is controlled.Presetting: Power station service = "oFF"ProgIf real power is generated in a certain application, thefollowing situations can arise:Case a.The generated real power is smaller than the demand.Additionally real power is delivered by the energy supplier.Power station service= "oFF"If no or a very small current is flowing through thecurrent transformer, all connected capacitor stages areswitched off one after the other.Power station service = "on"If delivery (power station service) and consumption ispossible, connected stages must remain connected tothe net, even if no current is measured.ProgrammingExample: Power station serviceGo to power station service in expanded programmingusing key 3.Confirm selection withkey 1.Text "on" flashes.ProgSet function "powerstation service" to "oFF" using key 2 and to "on" usingkey 3.Confirm with key 1 and continue with expanded programmingpressing key 3.Case b.The generated real power is bigger than the demand.Real power is supplied.Case c.The generated real power corresponds to the demand.In all cases the required reactive power is supplied bythe energy supplier, or even better, by a compensationsystem.The following situation can come into being. The neededreal power is completely generated (case c.) by the generator,and the reactive power is completely suppliedby a compensation system.There is no current flowing through the current transformer.If the power station service, by mistake, is on"oFF", the capacitor stages are disconnected. Then areactive current is flowing again through the currenttransformer. The controller detects a need for compensation,and connectes the stages again. The reactive currentis compensated. Again, no current is flowing.The problem is, that the number of switchings is increased.For power station service, especially in case c, the powerstation service should be set to "on".reactive powerBlindleistungreal powerWirkleistungL1L2L3klProphi10200610MGreactive power compensation systemBlindleistungs-KompensationsanlageDiagr.: Connection example power station serviceconsumerVerbrauchergeneratorGenerator= Key 1 = Key 2 = Key 3Page 27
