摘　　要：介绍了500kV郑州变电站大容量静止无功补偿(SVC)系统改造前的运行工况,分析了改造原因,提供了基于二次控制保护系统、光电触发与检测的晶闸管阀组和全封闭纯水冷系统等先进电气技术、设备的解决办法。详细分析了改造后SVC稳态控制调节策略、暂态控制调节策略,结合实际运行数据论证了改造后SVC系统对系统电压稳定作出的贡献。500kV郑州变电站SVC系统改造的成功,为改造类似引进国外SVC系统积累了丰富的经验。This paper introduces the operating-conditions of the SVC system before the upgrade, analyzes the reason of upgrade, and proposes the solutions based on the advanced electric technique and equipment such as control and protection system of secondary side, the thyristor valve group of photoelectric triggering and testing, and the fully sealed cooling water system. It analyzes the stable and transient control and adjustment strategies of the upgraded SVC system, proves the contribution to the voltage stability of the system based on the operation data. The success of the upgrade of SVC system in 500 kV Zhengzhou substation accumulates the successful rebuilding experience for similar imported SVC system.
