谐波环境下无功补偿装置串联电抗器的选择

摘要

In power systems, series reactance rate type reactive power compensator plays an important role to increase line power factor and improve the quality of system voltage. This article discusses the selection methods and principle of the reactance rate of series reactors, based on which the reactance rate design of series reactor under background harmonic voltage and harmonic current condition is studied. Finally, the selection and design methods for reac-tance rate are introduced combining with series reactor engineering design examples, to provide reference for project design and application of reactive power compensation.%在电力系统中，串联电抗率型无功补偿装置主要用于提高线路功率因数，改善系统电压质量的作用。讨论了传统的串联电抗器电抗率选择方法和原理，在此基础上研究了系统存在背景谐波电压和谐波电流情况下电抗率的设计问题，并结合工程设计实例分析介绍了电抗率选择与设计方法，为无功补偿工程设计与应用提供了参考。
