用途及性能

電力系統中的負載類型大部分屬于感性負載，加上用電企業普遍廣泛地使用電力電子設備，使電網功率因數較低。較低的功率因數降低了設備利用率，增加了供電投資，損害了電壓質量，降低了設備使用壽命，大大增加了線路損耗。為了改善電網功率因數低下帶來了能源浪費和這些不利供電生產的因素，必須使電網功率因數得到有效的提高。顯然這些無功功率如果都要由發電機提供并遠距離傳送是不合理的，通常是不可能的。合理的辦法就是需要無功功率的地方產生無功功率，即增加無功功率補償設備與裝置。

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.
