Improved Detection Method of Composition Current for STATCOM
摘要
Abstract
Aiming at some detecting error and delay of some existing detecting methods for composition currents in the case of unbalanced or distorted three-phase voltages, this paper proposes an improved ip-iq algorithm based on deeply investigating the theory of symmetrical component in three-phase circuits and the average theory. When using sine and cosine signal calculation block of fundamental positive-sequence voltage to reduce detected errors, and using average filters to replace low-pass filters to reduce the delay, the paper stabilizes the DC voltage by including the closed-loop feedback. The theoretical analysis and the simulation results verify the correctness and effectiveness of the proposed method.关键词
