摘要
Abstract
Low-load reactive power control function of conventional HVDC creates large firing angle or extinction angle of HVDC converter,which increases converter valve stress and power losses.Extinction angle backup control function of LCC-HVDC also leads to system status change and induce power fluctuations.In order to reduce those negative impacts,a reactive power coordinated control strategy for back to back hybrid-HVDC system based on Yunnan asynchronous interconnection project,using fast and precise reactive power control ability of MMC,is proposed.A electromagnetic transient model of Yunnan asynchronous interconnection project is build in PSCAD / EMTDC to verify effectiveness of proposed control strategy.关键词
