Abstract：Inorder to improve the energy eficiency of substationsand helpthe greenand low-carbon development of the power industry，this paper takes a 220kV prefabricated substation as an example.By systematically analyzing the influencing factors between building energy consumption and electrical equipment，an energy-saving optimization model based on artificial bee colony（ABC）improved algorithm is proposed.The optimization model first constructs amulti-variableobjectivefunction including the heat transfercoefficientoftheexternal wallof the building，the window-wallratio，theheat transfercoeffcientoftheexternal window，theinsulation thicknessoftheexternal wall，theassemblyrate，theloadrateofthemain transformeroftheelectricalequipment，theeficiencyofthestation transformer，andthelossof the high-voltage circuit breaker，anduses theABC algorithm to solvethe problem. Atthe same time，this paper verifies the optimization effctof the model basedon MATLAB R2O21 a platform and Grenjiansville software.The experimental results show thatthe energyconsumption eficiency of substation buildings increases from 88.9% to 95.2% after optimization，and the energy consumption efficiency of electrical equipment increases from 91.8% to 96.6% . The overall power utilization rate isstable between 92% and 94 % ，which is significantly better than the level before optimization.
