摘　　要：为解决井下电网在发生短路故障时易出现的越级跳闸问题,对数据传输的实时性有很高的要求,但目前井下微机保护装置所采用的通讯方式已经很难满足这一要求。针对这一问题,并结合EtherCAT通信高实时性的特点,提出了基于EtherCAT的煤矿井下防越级跳闸方案,并对系统的工作原理进行了分析。利用实验室现有Beckhoff公司的带有EtherCAT接口的设备,对该系统的主站和从站进行了设计,搭建了基于EtherCAT的井下电网防越级跳闸系统试验仿真平台。试验结果证明,该方案可以解决井下电网防越级跳闸的数据传输实时性问题。When short circuit fault occurs in the underground power grid ,the tripping override trip often appears .In order to solve the problem ,the communication modes used by the microcomputer protection device can ’t meet the requirement of real‐time .Aiming at this problem ,the anti‐grade trip solution for the coal mine power system based on EtherCAT was proposed in consideration of the better real‐time nature of EtherCAT .Using Beckhoff equipments with EtherCAT interface in the laboratory ,we design the master and slave control system ,making up the anti‐grade trip in coal mine power system .And the results demonstrate the solution can solve the real‐time demand of the anti‐grade trip in coal mine power system .
