In order to reduce the power loss of medium voltage distribution lines and realize the energy saving of distribution lines,this paper carries out energy-saving transformation of medium voltage distribution lines based on particle swarm optimization algorithm.The line loss current is obtained by using the root mean square current method,and the loss energy of overhead lines and cable lines is calculated as the data basis of the mathematical model of energysaving transformation.The mathematical model of line energy conservation and loss reduction is established through the objective function,and the model is solved based on particle swarm optimization algorithm to realize the energy-saving transformation of medium voltage distribution lines.The energy-saving transformation experiment is carried out in several stations of the medium voltage distribution network.After the energy-saving transformation,the average power factor of each station is increased by 52.8%,which verifies the feasibility of this method.Through the comparison of line loss electric energy between this method and other methods,it is found that the daily average loss electric energy under this method is only 45.5 kW·h.It is lower than other methods,which shows that this method has the best loss reduction effect and energy saving effect.
