摘要
为了研究传输线路发生故障时电路中的电压和电流的变化情况,利用电磁暂态仿真软件PSCAD/EMTDC对输电故障线路进行了建模,并在此基础上对其进行仿真分析。仿真结果表明,在PSCAD/EMTDC环境下建立的模型能够比较准确地描述在暂态过程中输电系统的动态特性,为现场运行以及故障分析提供参考。
PSCAD / EMTDC（ Power System Computer Aided Design / Electro-Magnetic Transient in DC system） software is used to establish the model of fault transmission line in studying its voltage and current. Based on it,the general faults of transmission line are simulated. Simulation results show that the model built in PSCAD / EMTDC can accurately simulate the dynamic behavior of fault system in transient process and provide references for field operation and fault analysis.
