【摘要】 随着以计算机为中心的电网调度自动化系统的引入 ,进入地区电网调度中心的信息量发生了巨大的变化 ,在复杂故障状态下涌入地调的大量信息 ,大大增加了运行人员判断和处理故障的难度 ,从而提高了事故扩大的概率。介绍一个用于地区电网调度中心计算机系统的电网警报处理和故障定位专家系统。该系统以 SCADA系统采集的故障数据为数据基 ,根据断路器、继电保护、隔离开关的状态 ,首先进行数据的滤波 ,然后启动依据规则的专家系统进行准确的故障定位 ,为调度中心的运行人员提供故障处理的依据。文中介绍了该系统的基本原理 ,系统的结构 ,推理机制 ,并讨论了它在地区电网中的作用。更多还原

【Abstract】 With the introduction of computer system, a vast amount of information will be poured into the power dispatching center, especially in some complicated fault situations. It will increase the difficulty to determine and process faults for the operators, therefore it could also initiate the expanding of fault area. This paper presents an expert system for alarm processing and fault diagnosis in local power system. Based on the collected message by SCADA system, and according to the status of circuit breakers, relays and isolating switches, fault message will be filtered at first, and then an expert system based on rules will identify the fault locations. The basic principle, the structure of this system, the inference engine, and also the functions of such system in local power system are discussed.更多还原
