煤矿井下供电防越级跳闸新技术
|
摘要
为了减少煤矿供电系统中电闸越级跳闸事故的发生,建议采用基于GOOSE闭锁的新型保护控制器。此保护控制器在原有的保护控制器上增添了监控模块和通讯模块,能够实现信息的快速传递,保证信息的安全。通过一系列试验显示,新型保护控制器能够在较短时间内准确找到故障发生点,自动关闭离故障点最近的开关,避免多数工作区域因越级跳闸而停电。
In order to reduce the coal mine power supply system switch tripping accidents, the author proposed the new blocking protection controller based on GOOSE. The protection controller adds monitoring module and communication module to the original protection controller, which can realize the quick transmission of information and ensure the safety of the information. Through a series of experiments,the results show that the new controller can accurately find fault protection in a relatively short time point, automatically shut down from fault point nearest switch, to avoid most of the work area for tripping and blackout.
