| Abstract: | The quality problems of negative-phase-harmonic sequence which are caused by electrfied railway traction power supply to power system are presented. The present scheme for characteristic ad faults are raised. The new plan and measme to solve this problem are led. The new ideas are provided to solve"electric pollution" caused by electrified railway power supply. |
