针对多静止同步补偿器(staticvarcompensator,SVC)对系统共同影响的问题,提出计及运行方式变化的多SVC布点方法。利用规范形分析,基于摄动方程2阶解析解信息建立拓展静态电压稳定边界的多SVC布点分析方法。首先根据静态电压稳定分析方法,确定系统危险运行方式(即距离系统电压崩溃最近的运行方式1;然后在该运行方式下,利用规范形方法对系统进行小扰动电压稳定分析,求出所有负荷节点的电压振荡曲线解析解;最后利用2阶解析解所给出的小扰动1阶振荡幅值和2阶振荡幅值信息,以多SVC布点多种方案对系统降低小扰动幅值的贡献为指标,给出多SVC布点结果。所提方法应用于IEEE30节点系统,试验结果表明,该方法相对于不考虑多点共同影响的多SVC布点方式,其静态电压稳定边界的拓展效果更好。
