In order to solve the problem of high control error and long control response time of power transformer thermal stability control,a thermal stability control method based on edge computing is proposed.This method introduces edge computing,sets the standard state value of equipment as the edge point value,estimates the thermal stability state of power transformer,and obtains the influence value of temperature change through power flow calculation based on the estimated value.Combined with the influence value of temperature change and thermal stability state estimation,the thermal stability control coefficient is calculated,the thermal stability control threshold is set,and the thermal stability control of power transformer is completed through threshold comparison.The experimental results show that the thermal stability control error and control response time of this method are low.which has certain feasibility and effectiveness.
