摘　　要：电力系统分析综合程序(Power System Analysis Synthesis Program,PSASP)对变电站母线拓扑结构做了简化,潮流计算中不能反映变电站内部各引流线及CT潮流变化。通过分析PSASP程序和3/2接线方式的特点,提出了增加母线节点法和断面定义法两种解决方案,并通过实际案例进行了验证。应用结果表明:两种方案均能够有效解决3/2接线中CT过载无法观测的问题。Power System Analysis Synthesis Program （PSASP） simplifys bus bar topological struc- ture of substation, power flow calculation can＇ t reflect each conduction line and CT power flow varia- tion inside substation. Through analyzing PSASP and the characteristic of 3/2 connection mode, puts forward 2 solution schemes： to add node of bus bar and section definition method, and through practi- cal example makes verification. The result shows that two kinds of schemes all can effectively solve the problems of CT overload can＇ t be observed in 3/2 connection.
