摘要
本文利用整个电网电流表达式进行数学推理变换,从电网电流中分离出基波有功电流,基波无功电流及谐波电流。这种方法只需两个积分器和两个增益即可,电路结构简单。应用Simulink进行仿真,仿真结果表明该检测方法具有很好的动态响应及畸变电流检测精度,对变化的负载可以很好地自适应跟踪检测。
This paper is based on increasingly the harmonic problem in power system. First,we introduced several ways on detecting harmonic. Then,we explained our new research of detecting harmonic. At last,we made a simulation with this new method and had approved this method was much faster with a higher precision and a easier structure than traditional detection ways.
