摘要

作为无功补偿领域应用最广泛的设备

SVC在增强电网稳定性、提高电网输送极限、阻尼功率振荡等方面有着重要的作用。随着电网规模的增加

在电力系统枢纽站点装设的SVC容量也越来越大。容量的增加导致阀组发热量的增加

笔者从高压大容量SVC阀组冷却系统设计出发

简要的阐述了阀组冷却系统的基本要求和构成

详细分析了高电压大容量SVC带来的阀组散热问题

提出了每级阀组采用双并联分支水路的冷却回路设计方案。

Abstract

As the most widely used device in the var compensation field

static var compensator（SVC） plays an important role in enhancing the grid reliability

improving the transmission limit and damping power oscillation

etc.The capacity of SVC installed in the key substations grows with the expansion of the power grid.This has put forward the heat increase of the valve.Based on the design of valve cooling-system of high-voltage & large capacity

this paper briefly summoned the basic demands and constitution of cooling-system

analyzed the heat-dissipation in detail

and proposed a new design scheme to adopt dual parallel branch waterway for each level cooling-circuit of valve.
