WebJun 14, 2012 · The VRS Droop shall be adjustable from 0 to 10% and must also be adjustable by PREPA’s Energy Control Center via SCADA. e) At zero percent (0%) droop, the VRS shall achieve a steady-state voltage regulation accuracy of +/-0.5% of the controlled voltage at the POI. WebIf the voltage deviation exceeds the normal range, the local WTG controller relies on the adaptive droop coefficient and the adaptive proportional setpoint weight-based rotor side converter controller to push the WTG toward its maximum reactive power limit to provide reactive power compensation during contingencies.
WebReactive droop compensation (droop) is an independent MVAR sharing control strategy that does not require hardware connecting AVRs, connection by peer-to-peer communications, or a network (local, dedicated plant wide, or enterprise wide).
