【摘要】 本文对供配电线路整定计算的自适应技术进行研究,提出了供配电线保护的自适应整定算法以及扰动域思想,并在此基础上对传统三段式距离保护进行改造得到自适应三段式距离保护。通过算例分析表明,自适应三段式距离在保证选择性的前提下,比前者有更大的保护范围及更高的灵敏度。更多还原

【Abstract】 This article studies the adaptive technology in the distribution line protection setting and proposes the adaptive setting algorithm as well as the thought of disturb region in the distribution line,and transforms the traditional triad distance protection to the adaptive triad distance protection.By analyzing the simple case,the method can guarantee the selectivity,and has a greater protective range.更多还原
