摘　　要：针对当前井下低压电网微机保护存在的问题,将时序鉴别、相敏检测等原理应用于井下低压电网综合保护系统中,采用大规模可编程逻辑阵列FPGA作为系统的控制核心,设计了基于FP-GA的井下电网智能保护系统。该系统重点解决了选择性漏电保护、相敏保护、不对称性短路故障、过载保护等长期困扰电网可靠性运行的问题。试验证明该系统反应灵敏、运行可靠。According to the problems existed in the micro-computer protection of the present low volage electric grid in the underground mine,the time sequence distinguishing,phase sensitive detection and other principles were applied to the comprehensive protection system of the low volage electric grid in the underground mine.The large scale programming logic device FPGA as the control key of the system was applied to design the intelligent protection system of low volage electric grid in the underground mine based on the FPGA.The system laid special stress on solving the selective leakage protection,phase sensitive protection,asymmetric short circuit fault,overload protection and other long term nagged grid reliability operation problem.The system would have reaction sensitive and reliable operation.
