phase selector

A fault phase selector based on MM transformation is proposed in this dissertation.

将形态学方法应用于故障选相元件，构造了一种新的选相元件；

Currently used fault phase selector components are compared and their characteristics and shortcomings are pointed out.

对目前实用的突变量及稳态量选相元件进行了比较,指出了其特点和存在的不足.

Using result of phase selector, according to the current features before and after the fault moment.

该判据利用选相元件的结果, 根据故障相在故障时刻前后的电流特征识别系统的非全相运行状态.

In general, the presented comprehensive phase selector can fit the complicate working environment well and has remarkable ability for phase selection, without influence of mutual inductance between lines.
