Larger system voltage unbalance degree causes larger capacitor voltagepulsation and negative sequence current.
不对称度的增加将进一步增大电容电压的脉动和负序电流的大小。
2
In power system, the voltagepulsation and deficiency or surplus of reactive power will have a great effect on the quality of electric power supply.
在电力系统中，电压的波动和无功功率的过剩和不足会严重影响供电质量。
3
The hysteresis wide is widened for decreasing switching frequency and energy losses, which causes the pulsation of instantaneous active power and direct current voltage.
