摘　　要：利用相对增益矩阵(RGA)和NI指数分析方法共同判断多台FACTS装置接入电力系统的交互影响。首先建立含静止无功补偿器(SVC)和静止无功发生器(SVG)的线性化电力系统输配电模型,根据所建模型求出控制系统的传递函数和电力系统的相对增益矩阵。通过RGA和NI指数分析方法共同找出两台静止无功补偿器之间、静止无功补偿器和静止无功发生器之间的负交互影响与电气距离的关系,并使用时域仿真证明此方法的可靠性。Making use of both relative gain matrix(RGA)and NI index analysis method to estimate the interaction of multiple FACTS AC devices placed in the power system was implemented,in which,having a power system’s linearized transmission and distribution model containing SVC and SVG established and then having the model based to get transfer function of the control system and the RGA of the power system;then through RGA and NI analysis method,having negative interaction relations with the electric distance between two SVC SVC and SVG found and finally having time domain simulation adopted to prove the reliability of this method.
