摘　　要：为实现在维持负载电压稳定的同时顺利进行不停电无冲击合环转供电,构建了静止同步补偿装置(static synchronous compensator,STATCOM),并引入下垂调节。通过改变STATCOM的控制策略,使其作为合环装置参与直流侧合环操作,并对该控制策略进行了分析。最后在PSCAD/EMTDC环境下,通过仿真验证了STATCOM在稳定电压与合环操作中存在的优势。In order to maintain the stability of load voltage and smoothly carry out the loop closing of power supply without power failure and impact,a static synchronous compensator(STATCOM)is constructed and droop regulation is introduced.By changing the control strategy of STATCOM,it can participate in the DC side loop closing operation as a loop-closing device,and the control strategy is analyzed.Finally,in PSCAD/EMTDC environment,the advantages of STATCOM in voltage stability and loop closing operation are verified by simulation.
