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 meet the real-time requirements of substation simulation, the design of protection and inspection range table in the simulation system is used to describe the corresponding relationship between the fault point and the required motion protection. The data sheet has been filled by hand, data errors can only be found through a wide range of fault tests, leading to a long project development cycle. On the basis of VC ++ EMS data, we study the method of automatically generating this data table. According to different types of equipment, the characteristics of the connection mode and the protection rules of the power grid, different protection configuration schemes, design breadth-first and depth-first hybrid search procedures are developed. The corresponding programs are developed by Visual C ++ and finally tested with an actual grid data. Prove automatically generated data table is completely correct.
