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.
