摘　　要：对单相电网电流进行了分解并提出一种新的谐波电流实时检测方法,该方法的算法简单且容易实现。在此基础上,根据具体的补偿要求,进一步研究了对单相电路基波无功电流的检测。计算机仿真结果有效地证明该方法能达到预期的效果。The current in single-phase circuit is decomposed, and a new detecting method for instantaneous harmonic currents in single-phase circuit is proposed.The arithmetic of this method is simple and it can be realized easily. In addition, according to the compensating object, the method of detecting fundmental reactive current in single-phase circuit is studied. Computer simulation results confirm the validity of the proposed approach.
