Abstract
There are some errors in detecting compensation command current by traditional ip-iq method under the condition of non-ideal voltage and conversion of current computing coordinate is complicated. In allusion to these problems,this paper presents a kind of improved ip-iq method suitable for non-ideal grid voltage on the basis of analyzing traditional ip-iq meth-od. This method uses sine and cosine information to extract module to replace phase-locked loop so as to correctly extract phase information of fundamental positive sequence voltage,remove impact of phase-locked loop on detection and reduce coordinate conversion and filter delay in current computation. Simulating analysis and experimental verification is conducted in MATLAB/Simulink software and distribution static synchronous compensator (D-STATCOM)prototype and results prove effectiveness and feasibility of the proposed method.关键词
