基于DSP和改进ip-iq算法的不对称系统补偿指令电流检测
Compensation command current detection based on DSP and improved ip-iq algorithm in asymmetric systems
摘要
Abstract
In order to solve the problem that the traditional ip-iq method can not accurately extract fundamental positive active and reactive current in three-phase asymmetric grid,the three-phase voltage is added to the abc/α-β coordinate conversion synchronously,and numerical calculation method is proposed to seek coordinates of instantaneous fundamental positive active (reactive) current vector in α-β coordinate system,and designs TMS320F2812 as the core sampling system.It is proved that the way to get fundamental positive compensation command is accurate comparing with traditional ip-iq detection under the conditions of three-phase asymmetric grid in MATLAB / SIMULINK simulation environment.关键词
