摘　　要：为了合理规划台区的配电终端布置,及时、准确掌握配电台区状态,应用数字孪生技术推进台区数字转型。针对台区较为理想的三相交流系统,基于通用型二级漏电保护装置与晶闸管投切电容器组,设计三相负荷不平衡调节与无功补偿。根据数字孪生通用结构架构数字化台区框架。分别就台区的变电设备与电网构建以数据链为基础的多物理场、多尺度数字孪生仿真模型与电网数字孪生模型。引用全生命周期管理理念,建立台区数字化管理数字孪生架构、运行流程及协同运作模式。结合数据挖掘策略,得到台区数字化调度模型。根据不同指标的评估结果可知,台区实现数字转型后不仅能加快运行状态的综合评估效率,还可准确预估电网接入点的可开放容量,改善三相负荷不平衡状况,为电力企业创造更大的经济价值。In order to reasonably plan the distribution terminal layout of the station area,timely and accurately grasp the state of the distribution station area,the digital twin technology is applied to promote the digital transformation of the station area is studied.For the ideal three-phase AC system in the station area,based on the universal two-stage leakage protection device and thyristor switching capacitor bank,the three-phase load imbalance regulation and reactive power compensation are designed.According to the general structure of digital twin,the framework of digital station area is constructed.The multi-physical field,multi-scale digital twin simulation model and power grid digital twin model based on data link are constructed respectively for the substation equipment and power grid.This paper introduces the concept of life cycle management to establish the digital twin architecture,operation process and collaborative operation mode of digital management in the station area.Combining with the data mining strategy,a digital scheduling model of the station area is obtained.According to the evaluation results of different indicators,the digital transformation of the station area can not only accelerate the comprehensive evaluation efficiency of the operation state,but also accurately estimate the openable capacity of the power grid access point,optimize the three-phase load imbalance,and create greater economic value for power enterprises.
