摘　　要：针对湖南发展特高压电网面临的动态无功支撑不足问题,结合无功补偿技术发展趋势,探讨湖南电网新增动态无功补偿的技术路线。通过FC、调相机、SVC、SVG四类技术的对比分析以及国内类似工程案例的实践总结,重点开展了新增调相机与新增SVG方案的分析论证。仿真结果表明,SVG动态无功支撑效果略逊于调相机的效果,但在动态无功与短路电流协同控制方面具有独到优势。In view of the shortage of dynamic reactive power support in Hunan UHV power grid development,the technical route of adding dynamic reactive power compensation in Hunan Power Grid is discussed.Through the comparison and analysis of four kinds of technologies such as FC,condenser,SVC and SVG,and the practice and summary of similar projects in China,this paper focuses on the analysis and demonstration of the new DC and the new SVG schemes.The simulation results show that the SVG dynamic reactive power support effect is slightly inferior to that of the condenser,but it has unique advantages in the cooperative control of dynamic reactive power and short-circuit current.
