摘　　要：电网启动智能成票系统是保证新设备投运操作安全进行的重要支撑手段,其核心是操作步骤的智能推理生成技术,多采用专家系统的方式实现。当前操作步骤智能推理生成技术研究的难点为知识库的结构设计和推理逻辑如何反映人类知识的条理性和内在逻辑关系,以及如何自适应动态变化的电网结构和电网运行方式。通过将概念图原理应用于智能生成系统,利用其表达能力强、直观、接近自然语言的特点,构建电网操作知识库,提出基于投影匹配算法的操作步骤推理策略,解决操作步骤智能生成的问题。在实际系统中的应用证明了该方法的正确性和实用性。The operation of intelligent ticketing system is an important technical support to ensure the safety of power grid operation.Its core is the operation of the intelligent reasoning technology,and it is realized by the way of expert system.The difficulty in the research of intelligent reasoning about the operation steps is that the structure design of the knowledge base and the logic of reasoning.How to reflect the level of human knowledge and the relationship between the logic and the internal logic,and how to change the structure of the power grid and the operation mode of the grid.By applying conceptual graph knowledge representation to operation order sheets system,taking advantage of its expression capability is strong,intuitive,and close to the characteristics of natural language to establish the knowledge based on the knowledge representation for conceptual graph.It proposes the corresponding operation steps reasoning strategy,and solves the problem of intelligent generation of operation steps.Through the application in the actual system,it proves the validity and the practicability of the proposed method.
