摘要：

This paper concerns the use of relative gain array (RGA) for analyzing the interactions among the power system dynamic voltage stability controls. RGA analyses for both static and dynamic voltage stability controls are carried out based on the multi-input multi-output (MIMO) transfer function matrix J(v)(s). By means of the singular value and RGA, the dynamic voltage stability and the controller interactions are analyzed. Then, the dynamic voltage stability control loop can be selected. A multi-machine power system with different working conditions is simulated for the demonstration of the proposed approach. Also, limitations and advantages of the use of singular value and RGA in the dynamic voltage stability analysis and control are discussed. The proposed approach is simple and can be easily implemented into large power system dynamic voltage stability control.
