摘要
介绍了静止无功发生器(SVG)的特点和工作原理,并且着重介绍了SVG的直接电流控制方法,分析了连接电抗和直流侧电容的几种常见参数选取方法,在分析了其中的优缺点后,采用工程实际常用的经验公式,计算了电抗和电容的取值。最后利用电磁暂态仿真软件PSCAD/EMTDC搭建了SVG的仿真模型,并验证了SVG的快速无功补偿能力。
This article described the characteristics and working principles of static var generator（SVG）,emphasized on the SVG direct current control method.Described several common parameter selection method of the connection reactance and the DC capacitor,after analyzed the pros and cons following the introduction of empirical formula commonly used in engineering practice to calculate the reactance and capacitance values.Finally,use electromagnetic transient simulation software PSCAD/EMTDC built the simulation model of SVG and verified the rapid reactive power compensation capacity of SVG.
