电网故障信息快速集成和智能诊断系统的研究

Study on quick fault information integration and intelligent diagnosis system for power system

针对目前电网故障诊断和处理中存在的问题,分析了故障信息的来源和快速集成中要考虑的问题,得出了对电网故障诊断和恢复的要求。提出利用Intranet平台,合理融合远程在线监测的关键数据,组建以保护和录波信息为主的电网重要信息快速集成系统,作为电网实时运行和快速故障分析恢复的参考。讨论了故障诊断数据的选取和信息集成中的问题,详细阐述了系统的网络结构和通信方式,给出了实用的主站和分站的结构图,合理优选了整个系统的通信方式,最后指出了电网故障信息快速集成和智能诊断管理的步骤及系统应具备的功能。

Aiming at the problems in fault diagnosis and processing of power system,the fault information sources and factors in quick integration are discussed,and the requirements for the fault diagnosis and restoration of power network are derived. A quick information integration system based on Intranet technology is put forward for power network real-time operation,fast fault analysis and system restoration,which integrates the main protection and fault recorder information and the key data of online remote monitoring. The selection and integration of fault information are discussed and the network structure and communication mode are expounded. The net-structure of main and subsidiary stations is proposed,and the optimum communication method is selected. The management procedures of quick fault information integration and intelligent diagnosis and the system functions are given.
