摘要
Abstract
When the distribution network load is operated under three-phase unbalanced conditions,the neutral(zero)line flowing through the current will increase the line loss and even damage the electrical equipment,which endangers the operation safety of the grid.According to the above problems,a method based on the intelligent phase-switching switch line to adjust the load phase se-quence to control the three-phase unbalance is proposed.Firstly,it introduces the dual switch structure topology and commutation principle of intelligent commutation switch in distribution network.Secondly,a multi-objective optimized commutation mathematical model with the lowest three-phase current imbalance of the end distribution network and the minimum phase sequence of the intelligent commutation switch device is established,and combined with NSGA-Ⅱ algorithm and terminal distribution,the network commutation strategy further realizes the control of the intelligent commutation switch.Finally,through the simulation of the example and the exper-imental analysis before and after the operation of the equipment in a certain district,the effectiveness of the commutation switch and the control method in the improvement of the three-phase unbalance of the end distribution network is verified.关键词
