摘　　要：500 k V输电线路固定串联补偿装置中,由于产品性能、选型和设计不当,串联补偿电容器组的爆炸事故在电力系统中时有发生,引起设备损坏、厂房烧毁、甚至线路大面积停电,损失巨大。电容器组安全工作对串补装置可靠性和电力系统的安全、可靠、经济运行影响重大。因此研究电容器组设计选型方案,提高串补装置安全性能是十分必要的。分析了电容器组的设计选型方案对串联补偿装置安全性能的影响,对不同的电容器选型和电容器组连接方式的爆破能量进行了计算,提出了电容器组设计的优化建议以提高串联补偿装置的安全性能。Capacitor explosion accidents happen at times due to the poor performance, improper type selection and scheme design of the capacitor bank in 500-kV transmission line FSC devices, which brings about huge losses such as equipment damage, plants burnout and even large-scale blackouts in the electric power system. The secure operation of capacitor banks will greatly influence the FSC reliability and the secure, reliable and economical operation of the power system. Therefore, it is essential to study the capacitor bank scheme design so as to improve FSC security. In this paper, the influences of the type selection and design scheme of FSC capacitor banks on FSC security are analyzed and the explosion energy of the capacitor banks with different design schemes is calculated. Finally, the suggestions on FSC optimization are put forward for FSC safety performance improving.
