有助于缓解低谷调峰压力。

Abstract

The influence of condenser in Shaoshan converter station on Hunan power grid at valley load period is studied in this paper. The simulation results show that the high voltage level is better regulated than the low voltage level when the condenser participates in the regional voltage control. When fault mode is considered

the effect of condenser on voltage stability is related to the level of phase-lead operation. The leading-phase operation of condenser can improve the system reactive power reserve level and relieve the pressure of peak load regulation at valley period by replacing load center thermal.
