摘要
并联电容器作为一种主要的无功补偿方式,广泛应用于各类电网高压线路当中。电容器投切开关是影响此类无功补偿装置可靠性与实际效果的关键部分。本文以电容器投切无功补偿装置的开关为对象,介绍了其应用现状及存在问题,结合理论分析,针对性地设计了1种智能投切装置,能有效抑制投切瞬间所产生暂态冲击,实现平滑投切。通过系统仿真与10 kV线路的工程应用,验证了其可行性与市场适应性。
Shunt capacitor, as one of the main reactive power compensation mode, is used widely in high voltage lines of various power network. The switching device of capacitor is the key part in as-suring reliability and actual result of such reactive power device. In this paper, the switch for reac-tive power compensation device of capacitor is taken as object, its present application status and ex-isting problems are introduced and, a kind of intelligent switching device is specifically designed based on theory analysis, which suppresses effectively transient impulse generated at instant of switc-hing and achieves smooth switching. Its feasibility and market value are verified through system simu- lation and application in 10 kV line.
