摘　　要：操作规则库是实现电网操作票自动生成的基础,操作票规则获取的实质是明确不同操作设备的先后操作顺序。以降低操作规则冗余度、提高操作票系统应用的灵活性为目标,提出一种基于粗糙集理论的操作票规则挖掘策略。分析电网调度操作特点,构建操作认知图;以实际电网操作票为数据源,构建初始操作规则库;基于上述分析,生成分类操作决策表;采用基于等价矩阵的快速约简方法对各决策表进行属性以及属性值约简,生成最简约决策表,从中提取操作规则,生成规则库。某地区电网实际算例验证了方法的有效性。Operation rules base is the basis to realize the automatic generation of operation ticket.The essence of extracting the operating rules is to ensure the operation sequence of different devices.To reduce the redundancy of rules and improve the application flexibility of the intelligent electric switching operation system,a kind of rules mining strategy has been proposed based on the rough sets.On account of the operating characteristics of the grid,construct the operational cognitive model,generate the operation decision table of classification.Adopting the equivalent matrix to conduct attributes reduction in order to obtain the optimal reductions of the table and then to extract operation rules.The validity of the proposed method is verified through arithmetic examples of a practical area network.
