基于電力電子技術(shù)的連續(xù)無功補(bǔ)償控制分析

摘要：隨著電力電子技術(shù)的迅速發(fā)展，電力系統(tǒng)中無功功率損耗問題也越來越突出。為保證系統(tǒng)或者電網(wǎng)的安全、優(yōu)質(zhì)運(yùn)行，必須對電力系統(tǒng)的無功補(bǔ)償和電壓調(diào)整問題進(jìn)行深入研究。如何平衡無功功率、提高電壓的穩(wěn)定性以及改善功率因數(shù)等，已經(jīng)成為電力系統(tǒng)中又一重大課題。本文從連續(xù)無功補(bǔ)償裝置的發(fā)展歷史入手，分析探討了其現(xiàn)狀和發(fā)展前景，并就無功補(bǔ)償?shù)哪康摹⒎椒ê脱a(bǔ)償原理加以分析，最后結(jié)合實(shí)例淺談了無功補(bǔ)償?shù)膽?yīng)用問題。 敘詞：連續(xù) 無功補(bǔ)償 電力電子 裝置 發(fā)展趨勢 Abstract：With the quick development of power electronics technique,the question of Var power loss in electricity system is fairly serious.It is essential to research the questions of Var compensation and voltage adjustment to meet system’s safe and quality operation.How to balance Var power and improve voltage stabilization and perfect power factors,they have been becoming great tasks.From developing history of continuously Var compensation equipments,this paper give a review to present conditions and development tendency,and analyze it’s aim and methods and compensation principle,It give an simple analysis to applied questions of Var compensation in accordance with an example at last.
