摘要
Abstract
When the short-circuit fault occurs near the substation,the great current and the rapidly rising current are huge threat to the power supply equipment. Therefore,high quality is needed to protector relay. A comparative analysis of DPU96,SEPCOS,and DCP2 was carried out in several aspects,including operation criterion,protection setting value,action speed,anti-jamming performance,and inverse time characteristic,etc.The work will contribute to the understanding of the model of short-circuit protection including di/dt+ΔI,and help to improve the design, manufacture and operation of DC protection for metro.关键词
