考虑系统运行状态转变的变电站内STATCOM与V QC协调控制研究
Study on Coordinated Control for STATCOM and VQC in Substation in View of Transformation of Operation State of System
摘要
Abstract
Aiming at problems of transformer tapping point in voltage quality control,frequent switch of capacitor bank and certain impact on system voltage by capacitor bank,this paper discusses join-in of static synchronous compensator in voltage quality control for substation.It proposes a discrimination method for system state based on local information in order to re-alize coordinated control strategy for STATCOM and VQC in substation and coordinate operation of tapping point of the on-load tap changing transformer,capacitor bank and STATCOM.By using BPA simulation software,it studies application ef-fectiveness of STATCOM device in substation.The simulation result indicates coordination of STATCOM and VQC is of ob-vious effectiveness for improving steady state and transient operation of the substation and decreasing switch times of tapping point of the transformer and capacitor.In addition,it proves better effectiveness of arranging STATCOM for two main transformers than only arranging STATCOM for one main transformer.关键词
