摘　　要：我国在全球能源生产和消费中所占份额最大,煤炭作为人类最早使用的传统能源,在我国能源消费结构中占据非常高的份额,且长期占比教高。一般来说,矿山电力系统存在零失压保护延时等问题,无法设置快断保护和过流保护设置。因此,构建超阈值防护制度是保障供电和矿山生产安全、保障员工安全的重要手段。矿山电力系统为矿山生产提供能源,生产安全和工人安全是两个核心内容。因此,我们将研究越级跳闸的原因,并在GOOSE(Generic Object Oriented Substation Event)的穿越性故障识别等技术的基础上提出优化技术方法,结合现场实际数据验证,确定最安全可靠的越级跳闸系统方案。China has the largest share in global energy production and consumption.As the earliest traditional energy used by human beings,coal has a very high share in China's energy consumption structure,and has a high proportion for a long time.Generally speaking,the mine power system has problems such as zero loss of voltage protection delay,and cannot set fast break protection and overcurrent protection settings.Therefore,building the over threshold protection system is an important means to ensure the safety of power supply and mine production and the safety of employees.Mine power system provides energy for mine production,and production safety and worker safety are two core contents.Therefore,we will study the cause of skip tripping,and propose optimization technical methods based on GOOSE(Generic Object Oriented Substation Event)'s technology of passing through fault identification,and determine the most safe and reliable skip tripping system scheme in combination with field actual data verification.
