摘　　要：不完全扩大内桥接线方式由于其经济性、灵活性等优点已经广泛应用在110 kV智能变电站中。但同时由于其接线方式的特殊性,也对一些问题的处理提出了新的要求。文章通过对110 kV不完全扩大内桥接线主要运行方式的分析,给出了其备自投的配置并讨论其逻辑行为。同时对电压并列问题、闭锁逻辑、联切小电源问题等进行分析,提出解决方案。The incomplete expanded inner-bridge connection has been widely used in 110 kV smart substations due to its advantages of economy,flexibility.However,the characteristics of such connection have also posed new requirements on handling some problems.Based on the analysis of the main modes in 110 kV incomplete expanded inner-bridge connection,this paper presents a solution of configuration of spare power automatic switching device and discusses its logic conditions.The scheme is then proposed to solve such problems as voltage parallel,latching logic and cutting small power lines.
