摘　　要：针对舰船电力系统的网络重构,建立了以负载恢复量、开关操作数和发电机效率均衡为多优化目标的舰船电力系统故障恢复模型,提出了一种带自适应离散断点算子和动态变异、交叉因子的改进离散差分进化算法进行求解。改进后的算法能有效地提高收敛速度,并克服传统差分进化算法收敛精度不高、易陷入局部最优的问题。舰船电力系统网络故障恢复算例表明,该方法能获得更好的系统重构方案,并具有较好的优化性能。With the load restoration, the number of switching operation and the balance efficiency of generators as the optimization goals, a multi-objective optimization model of fault restoration is established for network reconfiguration of shipboard power system,. An improved discrete differential evolution algorithm is proposed with the adaptive discrete breakpoints operator, dynamic mutation and crossover factors in order to enhance the speed of convergence effectively and solve the problem of local minimum of traditional differential evolution algorithm. The tests of shipboard power system service restoration show that better scheme of reconfiguration can be provided by this method, which possesses better optimization performance.
