摘要
为降低电网中的无功功率,提高功率因数,通常在低压供配电系统中装设无功补偿装置。介绍了影响功率因数的主要因素、提高功率因数和减少无功功率的方法及无功补偿的一般方式。
In order to reduce the reactive power and increase the power factor of the electric network, people install reactive-load compensation equipment in the low-voltage power supply and distribution system commonly. This paper introduces the main factors of influencing the power factor, the methods for increasing the power factor and reducing the reactive power, and the common mode of the reactive-load compensation.
