摘要
针对当前继电保护信息管理主站模型维护繁杂、故障排除困难的现况,提出一种基于Trie树的实时保护模型校核方法,实现继电保护信息主站与继电保护信息子站模型一致性校验、保护信息模型与通用保护模型完整性校验的要求。该方法基于知识库采用103规约中通用分类服务异步加载构建Trie保护模型树,以图形化方式定位展示模型差异,并按层次提供告警服务。通过设计实现与功能测试可知,该方法能在实际现场解决保护模型维护困难的问题,提高现场系统运维的效率。
In view of the complex maintenance and trouble shooting of the current relay information management master station model,a real-time protection model checking method based on Trie tree was proposed to achieve the purpose of checking the consistency of the relay protection information master station and the relay protection information substation model,and the integrity check of the protection information model and the general protection model.Based on the knowledge base,the Trie protection model tree was constructed by asynchronous loading of general classification service in 103 protocol.The model differences were located and displayed graphically,and the alarm service was provided according to the hierarchy.Through the design implementation and functional test,it could be seen that this method could solve the problem of difficult maintenance of protection model in the actual field,and improve the efficiency of field system operation and maintenance.
