Design and Application of Intelligent Fault Tolerant Analysis Software for Distribution Automation Based on Distribution Automation

为充分发挥配电自动化系统集中智能处理的优势,解决各种配电终端信号缺失、误送导致故障区间误判、数据分析错误等问题,通过对配电网设备产生的信息进行关联性分析,针对不同事件产生特征量信息,建立事件相关性计算原则,计算实际事件与期望事件的相关系数,进一步确定事件发生概率,实现配电网智能分析诊断;基于微服务架构,建立了配电网智能容错分析软件,满足现场高并发处理的应用场景,分析结果可为馈线自动化处理、配电网运维消缺提供数据支撑。

In order to give full play to the advantages of the centralized intelligent processing of the distribution automation system,and solve the problems of the lack of various distribution terminal signals,the misjudgment of the fault interval caused by the mistransmission,and the data analysis error,the correlation analysis of the information generated by the distribution network equipment is carried out.According to the characteristic quantity information generated by different events,the principle of event correlation calculation is established,the correlation coefficient between the actual event and the expected event is calculated,the event probability is further determined,and the intelligent analysis and diagnosis of the distribution network is realized.Based on the microservice architecture,an intelligent fault-tolerant analysis software for distribution network is established to meet the application scenarios of high concurrency processing in the field.The analysis results can provide data support for automatic feeder processing and distribution network operation and maintenance.
