摘　　要：多台DFACTS设备同时投入配电网时,设备的控制器之间存在交互影响,可建立并联逆变器的诺顿等效模型并利用RGA法定量分析多台并联逆变器之间的稳定性、网络参数及其交互影响的强弱关系。通过MATLAB仿真结果,可知逆变器的各控制参数对逆变器的交互影响具有不同程度的影响,因此,可通过协调控制各参数降低逆变器的交互影响。When multiple DFACTS dev ices are put into the distribution network at the same time,there is an interaction between the controllers of the devices.The Norton equivalent model of parallel inverter is established and the RGA method is used to analyze the stability,network parameters and their interaction relationship.Through the MATLAB simulation results,we can conclude that the various control parameters of the inverter affect the interactive influence of the distributor to different degrees,so the interactive influence of the inverter can be reduced by coordinating the size of the parameters.
