单侧电源220kV线路A相断开故障仿真计算分析

Simulation Calculation and Analysis on Linebreaking Fault of Phase A on One-teminal Power Supply 220 kV Line

采用BPA稳定分析程序,对单侧电源220 kV线路A相一侧断开后,220 kV线路电流和末端变电站变压器各侧电压进行仿真计算,并研究变压器带不同负荷对计算结果的影响。

Adopting the BPA stability analysis program,we simulated the linebreaking fault of phase A on one side of a one-terminal power supply 220 kV line, calculated the current of 220 kV line and the voltage on every side of transformer at terminal substation,and researched the effect reasoning by different load of transformer.
