摘　　要：针对不平衡电网中存在的负序电压分量对STATCOM的影响,提取三相基波正序电压作为同步参考信号,提出一种改进的ip-iq补偿电流检测方法。利用Matlab/Simulink仿真软件,对传统的ip-iq补偿电流检测方法和改进后的ip-iq补偿电流检测方法进行仿真。仿真结果表明,与传统的ip-iq补偿电流检测方法相比,该方法能够快速响应且准确跟踪电流变化,具有一定的可行性和优越性。Improved ip-iq compensation current detection method is presented by extracting the three-phase fundamental positive-sequence voltage of as a reference synchronizing signal in order to reduce the impact of negative sequence voltage component existed in the unbalanced grid on STATCOM.The simulation of both the traditional ip-iq compensation current detection method and the improved ip-iq compensation current detection method are conducted on Matlab / Simulink.The simulation results show that,compared with the traditional ip-iq compensation current detection method,the proposed method can respond rapidly and track current changes accurately and has certain feasibility and superiority.
