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。

Abstract

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.
