摘　　要：为达到变电仿真实时性的要求,仿真系统中设计保护巡检范围表来描述故障点与所需动作保护之间的对应关系。该数据表一直采用手工填写,数据错误只能通过大范围故障测试发现,导致工程开发周期长。在VC++EMS数据基础上,研究自动生成该数据表的方法。针对不同种类设备、接线方式的特点以及电网的保护配置规则,制订不同的保护配置方案,设计广度优先和深度优先混合搜索的流程,用Visual C++开发相应程序,最后以一个实际电网数据进行测试,证明自动生成的数据表完全正确。In order to achieve the real-time simulation in substation, the data scheme of protection and inspection range ,is applied to describe the relationship of fault point with protection. The data scheme is very time-consuming, and results are subject to human errors when the traditional artificial method is used. An automatic generation scheme of the module is studied based on EMS. According to different devices, connecting modes and principles of configuration protection, various configuration protection schems are de- signed. During topo-logical discovery, the depth searching and the width searching are alternately used. Schems are developed based on Visual C ＋ ＋ Tests of the automatically generated module are successfully performed based on data from actual power networks.
