摘要
对供配电线路距离保护整定计算进行研究,提出了改进型距离保护整定算法。通过算例分析表明,改进型算法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。
The setting calculations for the distance protection of the distribution lines are studied. The calculating example shows that the advanced algorithm has a greater protective range and higher sensitivity than the former on the premise of ensuring selectivity.
