基于電力電子技術的連續無功補償控制分析

摘要：隨著電力電子技術的迅速發展，電力系統中無功功率損耗問題也越來越突出。為保證系統或者電網的安全、優質運行，必須對電力系統的無功補償和電壓調整問題進行深入研究。如何平衡無功功率、提高電壓的穩定性以及改善功率因數等，已經成為電力系統中又一重大課題。本文從連續無功補償裝置的發展歷史入手，分析探討了其現狀和發展前景，并就無功補償的目的、方法和補償原理加以分析，最后結合實例淺談了無功補償的應用問題。 敘詞：連續 無功補償 電力電子 裝置 發展趨勢 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.
