| 摘要: |
| 智能站采用光纤传递数字和模拟信号，使常规站基于“短电流、断电压、拆跳闸”方式的二次安全措施理论不再适用于智能站。为解决传统人工拟票方式编制效率低、错误率高等问题，提出基于知识图谱与智能变电站配置描述文件(substation configuration description, SCD)的二次检修安全措施自动生成技术。首先，基于SCD文件和知识图谱构建配置数据库，并按照设定规则实现虚回路与软压板的半自动关联。其次，依据智能站规范中的二次安措编制准则，构建安措规则库并引入安措执行优先级编码字段。最后，由二次安措自动生成技术基于配置数据库与安措规则库完成检修设备二次信息的规则匹配，用于自动生成二次安措票。仿真结果表明，该技术能够根据现场检修任务自动正确生成二次安措票，提高智能变电站技改、消缺和校验的工作效率，降低人工编制错误率，为实现智能化运检一体提供参考。 |

| Abstract: |
| Intelligent stations have adopted optical fibers to transmit digital and analog signals, making the theory of secondary safety measures based on the “short current, off voltage, and split trip” method no longer suitable for such stations. To solve the problems of low efficiency and high error rate in traditional manual ticket preparation methods, an automatic generation technology of secondary safety measures based on a knowledge graph and substation configuration description (SCD) files is proposed. First, the technology builds a configuration database based on SCD files and a knowledge graph, and realizes the semi-automatic association between the virtual loop and the soft pressure plate according to the set rules. Second, from the compilation criteria of secondary safety measures in the intelligent station specifications, a safety measure rule library is constructed and the safety measures execution priority coding field is introduced. Finally, the automatic generation technology of secondary safety measures completes the rule matching of maintenance equipment secondary information based on the configuration database and safety measure rule library. This is used to automatically generate secondary safety measure tickets. The simulation results show that this technology can automatically and correctly generate secondary safety measure tickets based on on-site maintenance tasks, improve the efficiency of technical transformation, defect elimination, and verification in intelligent substations, and reduce the error rate of manual compilation. It provides a reference for achieving intelligent operation and inspection integration. |
