基于综合评分法的配网自动化终端差异化巡视策略

Comprehensive Scoring Based on Grading Operation and Maintenance Strategy for Distribution Terminal Unit

以提升配网自动化的实用化程度为目标,提出了一种基于综合评分法的配网自动化终端(distribution terminal unit,DTU)差异化巡视策略,综合DTU在馈线中的位置、进出线电流互感器(current transformer,CT)安装情况、点表确定程度、DTU硬件状况以及通信情况等多个维度,对设备进行分类,分别设定巡视项目以及周期,并应用于终端管理的全过程。实际应用表明,该策略可提高运维质量,提升配网应急能力,减轻运行人员劳动强度,提高用户满意度。

To sharpen the practicability level of distribution automation,this paper proposes a novel grading operation and maintenance strategy for distribution terminal unit（ DTU） based on comprehensive scoring method,integrating the position of DTU in the feeder,and install of current transformation（ CT） in all the incoming and outgoing power lines,the determination level of point table,DTU hardware and communication conditions,etc.. It introduces the classification of equipment,and sets the inspection items and cycle,and can be applied to the whole process of terminal management,so as to improve the dimensional quality,improve the emergency capability,reduce the labor intensity of operators,and improve user satisfaction. Moreover,the strategy is generalized so as to be able to be applied to any power distribution automation implementation with similar attributes.
