用途及性能

電力系統(tǒng)中的負(fù)載類(lèi)型大部分屬于感性負(fù)載，加上用電企業(yè)普遍廣泛地使用電力電子設(shè)備，使電網(wǎng)功率因數(shù)較低。較低的功率因數(shù)降低了設(shè)備利用率，增加了供電投資，損害了電壓質(zhì)量，降低了設(shè)備使用壽命，大大增加了線路損耗。為了改善電網(wǎng)功率因數(shù)低下帶來(lái)了能源浪費(fèi)和這些不利供電生產(chǎn)的因素，必須使電網(wǎng)功率因數(shù)得到有效的提高。顯然這些無(wú)功功率如果都要由發(fā)電機(jī)提供并遠(yuǎn)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(wú)功功率的地方產(chǎn)生無(wú)功功率，即增加無(wú)功功率補(bǔ)償設(shè)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.
