为了能智能地处理电网报警信息,开发了基于粗糙集的电网智能报警系统。该系统采用粗糙集理论对电网报警信息处理的规则进行学习挖掘,以这些规则为知识库对报警信息进行噪声滤除和逻辑推理等智能化处理。该系统实际应用到甘肃定西地区电网,经现场检验,该系统将智能化处理后的综合报警信息及时准确地提供给调度运行人员,减轻了调度员对电网分析的工作量,说明了基于粗糙集的电网智能报警系统能对电网报警信息进行智能化处理。 In order to intelligently process the alarm information of the power grid, a smart grid alarm system based on rough set is developed. The system uses rough set theory to study the rules of power grid alarm information processing and mining. Using these rules as knowledge base, the alarm information can be intelligently filtered by noise and logic reasoning. This system is actually applied to the power network in Dingxi district, Gansu province. After field test, the system provides timely and accurate intelligent alarm information to dispatchers and reduces the dispatcher’s workload on grid analysis. The grid intelligent alarm system can intelligently process the alarm information of the grid.
