电网运行异常状态诊断分析专家系统的应用研究

Application Research of Expert System for Diagnostic Analysis on Abnormal State of Power Grid Operation

随着新一代电力系统和坚强智能电网建设,对于电网运行异常状态诊断分析,研究如何选择信息要素和使用智能化技术方法,提高智能诊断水平十分有必要。在电网常见故障及异常状态分析的基础上,提出一种利用专家系统完成电网运行异常状态诊断分析的有效方法,分析了智能变电站信息采集特点和电网典型故障方式,介绍了一种一体化智能诊断分析工具,为电网运行异常状态智能诊断分析提供有效参考和辅助决策信息。

With the construction of a new generation of power systems and a strong smart grid,it is necessary to study how to select information elements and use intelligence technology to improve the level of intelligent diagnosis for the diagnosis and analysis of abnormal state of power grid operation. On the basis of the analysis of common faults and abnormal states of power grids,this paper proposes an effective method to diagnose and analyze abnormal state of power grid operation by using expert system,and then analyzes the characteristics of intelligent substation information acquisition and typical fault modes of power grid. Finally the paper introduces an integrated intelligent diagnosis and analysis tool,which provides effective reference and auxiliary decision-making information for intelligent diagnosis and analysis on abnormal state of power grid operation.
