摘　　要：为避免因设备故障造成变电站运行风险,设计基于数字孪生技术的变电站设备自动控制系统。通过测控保护模块采集变电站运行过程中产生的各类数据,利用站内通信模块将采集的数据传输到数字孪生模块,该模块依据接收到的数据运用数字孪生技术创建数字孪生虚拟变电站模型,根据虚拟变电站模型通过PLC自动控制模块实现变电站设备电压无功、安装质量以及运行状态的自动控制。实验结果表明,该系统对单一设备和规模庞大、结构复杂的变电站均具有较理想的建模效果,能将变电站设备电压、功率因数和安装位置偏差控制在合理区间内,在不同干扰下均能实现对变电站设备精准控制。In order to avoid the risk of substation operation caused by equipment failure,an automatic control system of substation equipment based on digital twin technology is designed.All kinds of data generated during the operation of the substation are collected by the measurement and control protection module,and the collected data are transmitted to the digital twin module by the station communication module.The module uses the digital twin technology to create the digital twin virtual substation model according to the received data.According to the virtual substation model,the automatic control of voltage and reactive power,installation quality and operation state of substation equipment is realized through the PLC automatic control module.The experimental results show that the system has ideal modeling effect for single equipment and large-scale and complex substation,can control the voltage,power factor and installation position deviation of substation equipment within a reasonable range,and can realize accurate control of substation equipment under different interference.
