对称分量法 meaning in Chinese

symmetrical component method
symmetricalcomponentmethod

Aiming at the unsymmetrical three phase voltages from inverter after a failure , the dissertation get the relationship among the positive sequence ( ps ) , negative sequence ( ns ) and the instantaneous symmetrical component of the ps , this build the foundation to detect the fault and to get the fault feature
针对逆变器故障后的电压输出的不对称性，利用对称分量法对逆变器输出信号进行分析，获得了逆变器输出信号的数字信号模型，为变频调速系统的故障检测与故障特征提取奠定了基础。 3
