用途及性能

电力系统中的负载类型大部分属于感性负载，加上用电企业普遍广泛地使用电力电子设备，使电网功率因数较低。较低的功率因数降低了设备利用率，增加了供电投资，损害了电压质量，降低了设备使用寿命，大大增加了线路损耗。为了改善电网功率因数低下带来了能源浪费和这些不利供电生产的因素，必须使电网功率因数得到有效的提高。显然这些无功功率如果都要由发电机提供并远距离传送是不合理的，通常是不可能的。合理的办法就是需要无功功率的地方产生无功功率，即增加无功功率补偿设备与装置。

Application and performance

Most of the load types in the power system belong to inductive load, coupled with the widespread use of power electronic equipment by power enterprises, so that the power factor of the grid is low. Lower power factor reduces equipment utilization, increases power supply investment, damages voltage quality, reduces equipment service life, and greatly increases line losses. In order to improve the energy waste caused by low power factor of the grid and these unfavorable factors of power supply production, the power factor of the grid must be effectively improved. Obviously, it is unreasonable and usually impossible for these reactive powers to be provided by generators and transmitted over long distances. The reasonable way is to generate reactive power where reactive power is needed, that is, to increase reactive power compensation equipment and devices.
