摘　　要：面对城市配网尤其是核心区域日益多元化的网架结构和越来越高的供电可靠性要求,在“双碳”目标下,大量的新能源接入,使配网结构和故障模型发生变化,传统的配网自动化产品在故障定位和隔离方面面临挑战,存在故障选择性差、负荷转供时间长等问题。本文介绍了一种适用于城市中心区域10 kV配网的配电差动保护及自愈装置的设计方案,并结合逻辑图分析了装置的具体实施方案。Faced with the increasingly diversified network structure and higher power supply reliability requirements of urban distribution networks,especially in the core areas,under the"dual carbon"goal,a large number of new energy connections will cause changes in the distribution network structure and fault models.Traditional distribution automation products will face challenges in fault localization and isolation,with poor fault selectivity and long load transfer time.This article introduces a design scheme for a distribution dillerential protection and self-healing device suitable for the 10 kV distribution network in urban central areas,and analyzes the specific implementation scheme of the device based on the logic diagram.
