| Abstract: | When the 110 kV rail traction power-supply lines are in operation, the negative sequence components and harmonic level of Xinzhou Power Grid exceed the national standard and have influence on the normal operation of generators. A static VAR compensation （SVC） scheme is proposed to reduce the negative sequence components and harmonic currents. In this paper, the performance of SVC and its working principles are researched and analyzed. The hazards of harmonics caused by rail traction power- supply gains control after launching the SVC into electrical railway. It illustrates that SVC ensures the stable operation of power system. |
