SVG的工程实践与风电场无功补偿装置的选型

Engineering Practice of SVG and Selection of Var Compensor in Wind Farm

介绍风电场常用的无功补偿方式以及SVG在工程实践中存在的问题。从SVG产品的IGBT损坏原因、SVG保护策略、重要元器件、通讯、采集板干扰、包装运输、运行环境、安装调试等方面分析了存在的问题,提出了解决思路,论述了风电场无功补偿装置的选型建议。从技术来看,SVG既可以补感性无功,也可以补容性无功,还可以平衡三相,反应速度快、占地面积小,这都是传统无功补偿和SVC无法匹敌的。

This paper introduce the reactive power compensation methods commonly used in wind farms and existing common problems of SVG(Static Var Generator)in practice projects.The problems existing in IGBT damage cause,SVG protection strategy,important components,communication,collection board interference,packaging and transportation,operation environment,installation and commissioning of SVG products are analyzed,the solutions are put forward,and the suggestions for selection of reactive power compensation device in wind farm are discussed.From the technical point of view,SVG can compensate not only inductive reactive power,but also capacitive reactive power,but also balance three-phase,fast response speed and small footprint,which are unmatched by traditional reactive power compensation and SVC.
