摘要
以变电站继电保护装置的逻辑仿真为研究背景,详细叙述了在搭建保护装置仿真模型时所遇到的主要技术难点和对应的解决方案。完成了基于网络拓扑的广度优先搜索法,并根据本课题的特点对该法做了相应的修改。建立了一次设备模块与继电保护装置模块的数据连接。重点研究和分析了保护装置仿真模型的数据结构,提出了以圈定保护启动范围为特点的继电保护改进逻辑仿真模型,并对数据结构中各模型表的层次关系做了相适应的改进。算例表明该继电保护装置仿真模型设计合理,拥有良好的应用前景。
Focusing on the study of logical simulation of substation protective relays, the paper introduces the major technical difficulties of building relay simulation models and corresponding solutions in detail. The achievements include employment of Breadth-First-Search method which is improved according to the status quo of the subject, establishment of data link between primary equipment modules and protective relay modules, detailed analysis of data structure of protective relay simulation model, and most importantly, proposal of protective relay simulation model improved by identifying area of relay pickup and improvement of the hierarchical relationship of model table in the data structure to fit the new relay simulation model. Case study shows that the proposed model is rationally designed and its practical application is promising.
