直流牵引供电系统继电保护整定与保护逻辑的分析

摘要

After the DC traction contact network of Masteel Nanshan Mining Company was put into operation some of the parameter settings and protection logic conflicted with ac-tual operation. Through analysis and study of the problem the protective settings and logic were gradually adjusted to suit production requirement, which has improved the reliability of power supply of the traction contact network.%南山矿业公司直流牵引接触网投入运行后部分参数及保护逻辑的设定与实际运行发生冲突，对此进行了分析研究，逐步调整了适合生产要求的保护定值和逻辑，提高了牵引接触网供电的可靠性。
