电缆系统站所终端配置对供电可靠性的影响评估

Assessment on Influence of Terminal Configuration of Cable System Station on Power Supply Reliability

本文概述了集中式馈线自动化的应用模式,基于供电可靠性分析构建针对电缆系统的评估模型。电缆系统按照故障类型可分为线路主干故障和环网单元故障,在考虑馈线N-1校验下,详细分析自动化故障处理过程,针对各类终端数量不同配置进行研究,并以此为基础开展供电可靠率分析研究,提出一种电缆系统的供电可靠性评估方法。最后,以某园区电缆系统为例,利用评估方法比选出最优自动化终端建设方案,为园区自动化建设提供实用性指导。

This paper summarizes the application mode of centralized feeder automation and sets up the evaluation model for cable system based on power supply reliability analysis. According to the fault types,cable system can be divided into line trunk fault and ring network unit fault. Considering the feeder N-1 verification,the process of automatic fault handling is analyzed in detail and the study is performed in accordance with the number and configuration of various terminals. Based on this,the power supply reliability analysis is performed and a power supply reliability evaluation method of cable system is proposed. Finally,taking the cable system of a park as an example,the optimal automation terminal construction scheme is selected by using the evaluation method,which provides practical guidance for the automation construction of the park.
