一种改进的ip-iq无功电流检测方法及其应用
An improved ip-iq reactive current detecting method and its application
摘要
Abstract
Static var compensator (STATCOM) is a widely used power electronic device for dynamic reactive power compensation, and ip-iq operation mode is generally used for its reactive command current detecting, However, it is required that the installation position of STATCOM must be consistent with the detecting point of load current when using the traditional ip-iq method, in which the load reactive current component is directly used as the command value of STATCOM output current limiting the flexibility to choose the installation location of STATCOM. To solve this problem, this paper proposes an improved ip-iq reactive current detecting method based on the principle of instantaneous power balance, and the voltage phase information of the detecting point and the compensating point is introduced, making the installation position of STATCOM is no longer limited by the detecting point. The improved ip-iq current detecting method is applied in the system with STATCOM across the transformer, and the simulation results verify the correctness and effectiveness of the proposed method.关键词
