摘　　要：本文介绍了电磁暂态仿真软件PSCAD/EMTDC的运算模式以及自定义建模的两种技术路线,对C语言静态变量的使用所导致的内存调用冲突问题以及自定义模块源代码与PSCAD/EMTDC工程的连接机制进行了分析,并结合工程仿真实际,提出了自定义模块的一般测试方案。基于PSCAD/EMTDC程序与C语言接口技术建立的行波保护系统仿真模型能有效识别线路故障并正确动作,仿真结果表明,自定义模块的应用有效地弥补了自带元件库的不足,增强了仿真的灵活性和工程实用价值。The paper introduces the main operation mode of the open language interface in PSCAD/EMTDC and two technical methods of user-defined modeling. The paper analyzes the memory conflict problem caused by the use of static variables and the connection mechanism between user-defined module＇s source file and the project of PSCAD/EMTDC. The paper puts forward general test schemes for user-defined modules by combining with engineering simulations. A transient traveling wave relay protection model defined by C language has a good performance.Simulation results indicate that the application of the user-defined module can effectively improve the flexibility of simulation.
