Based on the symmetry component theory, a method of the motor protection is presented by measuring positive, negative and zero sequence current component.
基于对称分量法理论，提出了基于检测正序、负序、零序电流分量的电动机保护方法。
Compared with the previous methods, the Newton-Raphson method is used not only for solving the positive equation, but also the negative and zero sequence equations.
与已有方法相比较，所提方法不仅在正序方程中，而且也在负序和零序方程中采用牛顿法修正方程。
