Compensation Capacity Selection and Performance Improve for SVC

摘要

The industrial application of static VAR compensator (SVC) is becoming more and more widely.It has many outstanding functions,such as respond rapidly for changes,compensate reactive power dynamically,reduce harmonic,suppress voltage fluctuations and flicker,and improve the negative sequence problem.This paper,from the above power quality problems,analyzes SVC capacity selection principle and the compensation effect.Meanwhile,the compensation performance evaluation method for an installed and operational SVC is also given.When device can't achieve the expected compensation effect,some improvement strategies are put forward further more.
