Research on the application of digital twin in coal mine power grid

  • 摘要: 立足于数字孪生的基本概念和内涵,分析了数字孪生技术在煤矿电网中的应用优势:以同步实体运行状态、数字化模拟运行 2 种手段来辅助煤矿电网的运行管理,具有数据驱动、实时更新、同步反馈的特点。提出了由煤矿电网物理实体层、煤矿电网数字孪生模型层、用户管理服务层、数据交流层组成的煤矿电网数字孪生体系基本架构,从物理实体、数字孪生模型2个方面探索了煤矿电网数字孪生体系运行模式。介绍了建立煤矿电网数字孪生体系的关键技术:煤矿电网数字孪生模型构建、智能数据采集、基于5G的智能通信、数字孪生智能数据库、数字孪生设备智能管理平台。给出了数字孪生技术在煤矿电网中的具体应用场景,包括煤矿井下电气设备状态评估、煤矿电网故障定位和保护、煤矿电网智能监控、煤矿井下线路智能巡检。将数字孪生技术应用在煤矿电网中,对煤矿电网的状态和运行进行动态仿真建模,一方面可以满足当今规模庞大的煤矿电网相对地面电网更高的运行要求,保障煤矿生产安全性,另一方面可推进煤矿电网的智能化进程,实现数据资源高效合理利用。
