摘　　要：从高抗的功能、无功补偿及过电压限制对1000kV高抗运行方式的要求，现有500kV高抗的设计、运行、试验的情况以及取消1000kV高抗回路隔离开关对占地及投资的影响等方面对1000kV高抗回路的接线设计进行优化，结果表明，1000kV变电站取消隔离开关，可以大量节约占地和投资，是可行的。As one of the most important equipment in UHV stations, the shunt reactor is vital to the safety and stability of the power system. According to studies on the function of the shunt reactor,operation requirements for the 1000kV shunt reactor in terms of reactive power compensation and over-voltage restriction, and with consideration to the existing 500kV shunt reactor with regard to its design, operation, testing and occupied areas, as well as the investment effect for canceling the disconnector of the shunt reactor,the connection of the 1000kV shunt reactor circuit is optimized. The result shows it is feasible to cancel disconnector for 1000 kV substations, and it can save occupied areas and investment.
