基于专家系统的变电站监控信号智能处理系统

Substation signals intelligence processing system based on expert system

为了减轻变电站运行人员的工作负担,辅助故障快速判断,提高运行人员技术水平,在深入总结变电站异常和故障类型的基础上,构建了一个多层次的故障推理模型,结合网络拓扑技术,实现了一个基于专家系统的变电站监控信号智能处理系统.系统的监控信号分析处理功能全面,快速定位机制确保值班员能迅速确定故障信息所在间隔,能准确报告变电站主要故障,并结合专家知识库出具故障报告,提供故障处理指导.系统具备故障模拟及培训功能.该系统在变电站实际应用中取得了良好的效果.

In order to reduce the burden of substation personnel and support rapid fault judgement, as well as to improve the technical level of substation personnel, on the basis of summarizing the types of substation＇ s faults and exceptions, a multi-level fault model of reasoning has been constructed, and a substation signals intelligence processing system is realized by using network toplogy technology. The function of analyzing and processing the supervisory control signals of this system is comprehensive. Its rapid locating mechanism can ensure the man on duty to recognize the bay of fault quickly. It can show substation＇ s main faults exactly and give fault report based on expert repository with fault processing guide. It also has fault simulating and training function. This system obtains good results in the practice of substation operation.
