摘　　要：为避免煤矿供电时频繁发生越级跳闸现象,文章应用数字式光纤纵差保护技术,对防越级跳闸系统的硬件部分及软件部分进行设计,并进行供电系统模拟测试。测试结果表明,在开关正常动作和开关无法动作两种情况下,该技术均能有效防止供电系统出现越级跳闸的故障,为煤矿等复杂供电网络提供了安全保障。In order to avoid the frequent occurrence of leapfrog tripping during power supply in coal mines,this paper uses the digital optical fiber longitudinal differential protection technology to design the hardware and software of the anti-leapfrog tripping system,and carries out simulation test of the power supply system.The test results show that the technology can effectively prevent the fault of leapfrog tripping of the power supply system under the condition of normal operation and failure of switch,providing a safety guarantee for complex power supply networks such as coal mines.
