摘要
针对矿井供电系统越级跳闸事故发生频率高影响供电系统稳定运行的问题,通过对矿井越级跳闸的原因分析并明确越级跳闸事故发生原因是供电系统失稳、开关不合理、电路速断方式落后、整定方法不当等造成的。根据越级跳闸事故发生原因,设计了基于GOOSE通信网络的防越级跳闸系统,给出了系统各模块的硬件选型,根据现场应用验证了防越级跳闸系统的可行性,为矿井供电稳定开采运行提供保障措施。
In view of the high frequency of skip tripping accidents in mine power supply system,through analyzing the causes of skip tripping in mine,it is determined that the skip tripping accidents are mainly caused by the instability of power supply system,unreasonable switch,backward circuit quick break mode and improper setting method.According to the causes of skip tripping accidents,the anti skip tripping system based on GOOSE communication network is designed,and the hardware selection of each module of the system is given.The feasibility of the anti skip tripping system is verified according to the field application,which provides guarantee measures for stable mining operation of the mine power supply.
