如何检测三相不对称电压的各序分量

How to Test the Several Order Components of the Three phase Asymmetric Voltage

为了解决三相不对称电压的检测问题 ,分析了三相不对称电压正序、负序和零序分量的检测方法 。

In order to solve the testing of the three phase asymmetric voltage, the testing method of positive order and negative order and naught order components of the three phase asymmetric voltage is analyzed in this paper. The electrical circuit that can directly test order components, i.e., the principle of order component filter, is introduced on the basis of the above method.
