摘要

传统10 kV配电网越级跳闸、扩大停电范围的情况时有发生，影响客户用电可靠性，降低用电体验感。文章在现有10 kV配电自动化开关配置基础上，通过优化自动化开关级差保护定值，精准匹配保护时限，实现故障快速定位与隔离，并结合工作中的实际案例，验证级差保护在压降停电时户数、提升供电可靠性、减少频繁停电投诉等方面的实际成效。

Abstract

Traditional tripping escalation in 10 kV distribution networks

which expands the outage range

occurs from time to time

affecting customer power supply reliability and reducing the user experience. Based on the existing configuration of 10 kV distribution automation switches

this paper optimizes the protection grading settings of automated switches to achieve proper time coordination

enabling rapid fault localization and isolation. Combined with practical engineering cases

it verifies the actual effect of graded protection in reducing customer outage hours

improving power supply reliability

and reducing complaints about frequent outages.
