POWER SYSTEM SUPERVISORY CONTROLLER OF UPFC

摘要

The present invention relates to a power system controller of the UPFC cooperate to reduce the power grid voltage compensation and has been developed to improve the reliability of the system to control algae and promote utilization of the UPFC operator convenience of synthesis bird controller (UPFC).; The present invention, by acquiring the system information from the neighboring grid to generate a voltage command value V ^*, birds command value P ^*, Q ^* according to an algorithm K ₅ (S) of the UPFC power system coordination controller (40) UPFC controller therefor is configured so as to input the parallel inverter controller 110 in series with the inverter controller 210 (30); Series inverter through a series inverter controller (210) is on at all times is operating in the grid loss minima, parallel inverter through the parallel inverter controller 110 is subject to the control voltage based on the earthquake bus; And so as to avoid overloading the neighboring lines or neighboring substation in an accident the series inverter of the series inverter controller (210) contributes to the bird control, a parallel drive of the parallel inverter controller 110 includes a drive such that the grid voltage is maintained by compensating for the reactive power and that with its features.
