摘　　要：光伏电站配置无功补偿装置可提高光伏输送容量和系统的稳定性,并防止电压崩溃。目前电力系统中最常用的无功补偿装置为SVG,本文深入研究了SVG的工作原理和系统构成,并针对光伏电站的无功补偿范围、补偿位置及补偿容量进行了理论分析与计算。最后,以某个专线接入的大型光伏电站为例提出了无功配置方案,研究结果对光伏电站的工程设计及无功补偿技术研究具有指导作用。Provision of reactive power compensation device for photovoltaic power plant can improve photovoltaic transmission capacity and system stability and prevent voltage collapse. The most common reactive compensation device in present power system is SVG. In this paper,the operating principle and system constitution of the SVG is studied deeply, the theoretical analysis and calculation on the reactive power compensation range, compensation position and capacity of photovoltaic power plant are analyzed and calculated. Finally,the reactive power allocation scheme of a large photovoltaie power plant connected by a special line as an example is proposed. And the study result plays an instructive role for the engineering design of photovohaic power plant and the study of reactive power compensation technnlno-v
