摘　　要：结合某地区220kV变电站静止无功补偿器(SVC)与固定无功补偿设备配置情况,利用PSASP仿真工具平台对SVC与固定无功补偿设备统一控制后的系统稳定情况进行了计算分析,结果表明,通过SVC与固定无功补偿设备的统一协调控制,能有效改善地区电网的稳定状况,同时提出SVC与站内固定电容器、电抗器要纳入全站统一的无功控制策略中,增加无功功率时考虑先切固定电抗器(或晶闸管控制电抗器TCR)、后投固定电容器,减少无功功率时考虑先切固定电容器,后投固定电抗器,正常方式时SVC可以保留最大的动态容性无功储备的策略和建议。Combining the configuration of SVC and fixed reactive-load compensation equipment in an 220 kV substation,this paper calculated and analysed system stability situation after unified control of SVC and fixed reactive power compensation equipment using PSASP.The results show that the coordinated control can effectively improve the stability of regional power.This paper also points out that SVC,station fixed capacitor and reactor should be included in the total reactive power control strategy.Fixed reactor（TCR）should be cut before put into the fixed capacitor while increasing reactive power,fixed capacitor should be cut before put into the fixed reactor（TCR）while reduceing reactive power,SVC can keep the biggest dynamic reactive power reserve capacity in normal way.
