当无功功率不平衡时，将会导致系统电压降低、电能质量下降、功率因数降低、线损增加等问题。
When reactive power is unbalance, it will cause some problems, such as lower voltage, worsen voltage quality, lower power factor and increase line loss.
提高功率因数的一个重要办法就是无功补偿。 另外通过远动监控、线损统计、线路改造等措施，也可以降低线损。
The reactive power compensation is a important means of enhancing power factor, otherwise, by remote control, loss statistic and line rebuilding also can reduce the line loss.
在电能输送和分配过程中，电力网的有功功率损失和电能损失统称为线路损失，简称线损。
In the transporting and assigning process of the electric power, the active power loss and electric power lose of the electric power net are known as the line loss.
