农用电网无功电流检测法的研究

Study on the Method of Detecting Reactive Current of Agricultural Power Network

基于瞬时无功功率理论,对农用电网无功电流的检测方法进行了研究。按照不同的补偿要求,提出了两种具体的无功电流检测方法,即同时检测出基波无功电流与谐波无功电流,或者仅检测基波无功电流分量。利用Matlab软件进行计算机仿真研究,仿真结果有效地证明了该方法的正确性。

Based on the instantaneous reactive power theory, the method of detecting reactive current of agricultural power network is studied. According to the different compensating objects, two specific methods of detecting reactive current are put forward. That is, detecting fundmental reactive current and harmonic reactive currents simultaneously, or detecting fundmental reactive current only. Making use of MATLAB software, computer simulation studies are made to validate the proposed method correct availably.
