The development of static reactive power compensation device in rural power distribution system 農(nóng)網(wǎng)變電站無功補償系統(tǒng)
Aimed to the above mentioned defects of reactive power compensation devices being used widely up to now and no value of practical application , the article described the principle of compensation reactive power controlled by intellectual static auto - compensation system which is of every phrase active power compensation and three phrase balance compensation 針對這些實用性不強的無功功率補償裝置,本文提出了采用靜止式無功功率自動補償分相控制的系統(tǒng)總體方案,使補償響應(yīng)速度和補償精度大為提高。
On the base of widely investigating and researching , author deems that the conventional reactive power compensation devices used by consumer had many defects with among others : lower response time , remaining residual voltage on the compensation capacitors , and so on . because of existing improper trigging time , it is impossible to realizing balance compensation for 3 - phrase unbalance loads 本文在充分調(diào)研的基礎(chǔ)上,認為目前采用的傳統(tǒng)的無功功率補償裝置存在響應(yīng)速度慢、觸發(fā)時刻不合適、補償電容器上有殘壓、不能實行三相平衡補償、對電網(wǎng)產(chǎn)生污染、不能消除負荷本身產(chǎn)生的高次諧波等弊病。
With the development of the technology of compensating the harmonics and var in the power system , the reactive power compensation device with bidirectional compensate timely is in great need in research on advanced reactive power compensation . and the device itself does not pollute power system with harmonic 隨著電力諧波治理和無功補償技術(shù)的發(fā)展,開發(fā)和研制能夠?qū)ο到y(tǒng)無功功率進行雙向動態(tài)補償?shù)难b置,而裝置本身又不會對系統(tǒng)造成諧波污染,已成為現(xiàn)代無功補償技術(shù)研究的熱點。
