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 differ-ent 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.
