| Abstract: | The balance status of three-phase voltage in power system is a main index of electrical energy quality. The unbalance of three-phase loads and three-phase parameters could arouse three-phase voltage unbalance in power system. The definition and national standard of three-phase unbalance in power system were expatiated. The bad influence and compensation methods were introduced. |
