介绍SVG的基本工作原理、特点和在电网输变电系统、风电场领域中的应用。在此基础之上结合SVG的应用现状以及研究中涉及的散热计算、损耗计算、控制策略和电磁干扰等方面应注意的问题与采取的措施。无功补偿对维持电力系统的稳定性和经济运行,改善电能质量有至关重要的作用。无功功率会造成公用电网设备容量和线路损耗的增加,更重要的是无功功率的波动会引起电网电压的波动, This paper introduces the basic working principle and characteristics of SVG and its application in power transmission and distribution system and wind farm. Based on this, the application status of SVG and the problems to be paid attention to and the measures to be taken in the calculation of heat dissipation, loss calculation, control strategy and electromagnetic interference are studied. Reactive power compensation plays an important role in maintaining the stability and economic operation of power system and improving power quality. Reactive power will cause the capacity of public power grid equipment and line loss increase, more importantly, the fluctuation of reactive power will cause the fluctuation of grid voltage,
