基于SCD文件解析的变电站二次系统智能运检方法

Intelligent Operation and Inspection Method for Substation Secondary System Based on SCD File Analysis

变电站是输配电系统中的核心部分,对电网的稳定运行起到重要影响。当变电站中的设备出现故障时,若不能及时地获取运检信息,则会导致运检结果不准确,影响电网的安全运行,因此研究基于科学引文数据库(Science Citation Databas,SCD)文件解析的变电站二次系统智能运检方法。基于SCD文件解析方式,对变电站二次系统中的设备数据进行检验,以一致性数据节点模式配置智能运检流程。通过关联规则联系二次系统中的设备数据,通过数据置信度和支持度获取各设备组之间的关键点信息,完成变电站二次系统的智能运检。实验结果表明,以某省120 kV变电站中的设备故障数据为测试对象,选择5组不同的故障类型,所使用运检方法的查准率均在98.5%以上,具有较好的应用效果。

Substation is the core part of power transmission and distribution system,which plays an important role in the stable operation of power grid.When the equipment in the substation is out of order,if the information of operation and inspection can not be obtained in time,the result of operation and inspection will be inaccurate,which will affect the safe operation of the power grid,the intelligent operation and inspection method of substation secondary system based on Science Citation Databas(SCD)file analysis is studied.Based on the analysis of SCD file,the equipment data in the secondary system of substation is checked,and the intelligent operation and inspection process is configured in the consistent data node mode.The equipment data in the secondary system are connected by association rules,and the information of the key points among the equipment groups is obtained by data confidence and support,and the intelligent operation inspection of the secondary system in substation is completed.The experimental results show that the accuracy of this method is above 98.5%,and it is effective to select 5 groups of different fault types based on the fault data of 120 kV substation in a province.
