摘　　要：介绍一种新的基于DSP的高压电网自适应选线式漏电保护方案,采用自适应欠补偿方式、随机整定与相敏比较来判断故障支路,实现选择性漏电保护,具有灵敏度高,选线准确,并适用于不同接地方式的特点。Introduces a new DSP-based adaptive line-selective leakage protection program of high-voltage power network. It adopts adaptive under-compensation, random tuning and phase-sensitive comparison to judge the fault branch and achieve selective leakage protection, and provides high sensitivity, line selection accuracy, and suitable to different grounding.
