摘　　要：电力系统电磁暂态仿真是测试继电保护装置性能的重要手段,也是分析交直流混合输电系统可靠性的重要方法。目前国内对电网动态仿真大都是对机电暂态过程的仿真,故电网数据也按照机电暂态仿真软件数据格式存储,从而造成了电磁暂态仿真数据的匮乏。在详细分析了机电暂态仿真软件BPA与电磁暂态仿真软件PSCAD差别的基础上,介绍了一种BPA向PSCAD的自动模型转换的实现方法,为电力系统电磁暂态仿真提供可靠的数据支撑,并且通过算例在2种软件下的电气拓扑结构和动态特性的比较,验证该转换方法的有效性和准确性。The electromagnetic transient simulation of electric power system is an important test means of relay protection performance,as well as a main reliability analysis method of AC/DC hybrid transmission system. The present power system transient simulation in China is mostly for the electromechanical transient process and the grid data are consequently stored in the data format of eleetromeehanical transient simulation software,resulting in the shortage of simulative electromagnetic transient data. The difference between BPA（a kind of electromeehanieal transient simulation software） and PSCAD（a kind of electromagnetic transient simulation software） is analyzed in detail and an implementation method of model conversion from BPA to PSCAD is presented. BPA and PSCAD are applied respectively to cases and its electric topology and transient characteristics are compared between two kinds of software,which proves the effectiveness and accuracy of the proposed conversion method.
