摘　　要：针对3×3阶及以上控制系统,引入了一种新的基于相对归一化增益矩阵(RNGA),配对准则的FACTS控制器间交互影响定量分析方法。该方法结合了系统的稳态、动态特性,与控制器类型相独立,计算量大大减少,能够更准确的定量分析变量对间交互影响的大小。建立了含静止同步补偿器(STATCOM)和静止无功补偿器(SVC)的四机两区域系统线性化模型,利用RNGA分析方法得出不同电气距离和安装位置对控制器间的交互作用的大小,并时域仿真验证,仿真结果与RNGA原理的分析结果一致,表明了RNGA准则在分析交互影响作用上的可行性和有效性。Aiming at 3×3 and higher dimensional systems, the relative normalized gain array（RNGA） is applied to assess the interaction between FACTS controllers. The proposed method considers both the process steady-state and transient information in measuring the loop interactions without requiring the specification of controller type but less calculation. Firstly a linearized model four-machine twoarea power system installed SVC and STATCOM is built. Based on RNGA analysis method, this paper quantifies the negative interaction among FACTS controllers and shows the the influence caused by the system electrical parameters. The detailed simulation results validate the validity and effectiveness of RNGA method in analyzing interactions of FATCS controllers.
