摘　　要：配电网发生多处故障时,配备的物资和抢修小队不能满足每个故障任务的需求,因此提出基于适应度的配电网多故障抢修任务分配策略。首先量化配电网抢修故障任务、抢修小队和物资仓库的模型,然后定义小队适应度、物资适应度这2个外部适应度指标,分别描述抢修小队、物资仓库与故障任务之间的匹配程度;定义优先级适应度、进度适应度这2个内部适应度指标,分别描述各个故障任务的优先顺序和其抢修进行程度。综合外部适应度指标和内部适应度指标可得出各个故障任务的总适应度值,进行比较后得出最优的任务分配策略。对IEEE 33节点系统进行仿真,仿真结果验证了所提分配策略的有效性和实用性。When multiple faults occur in distribution network,both the supplies and teams can not meet the requirements of each fault repair task,aiming at which,a task allocation strategy based on fitness is proposed for the multi-fault repair. The fault task model,repair team model and material warehouse model are quantified,two external indexes,i.e, team fitness and supply fitness,are defined to respectively describe the matching degree between repair team and fault repair task and that between material warehouse and fault repair task,while two internal indexes,i.e, priority fitness and schedule fitness,are defined to respectively describe the priority of fault repair task and its repair schedule. The overall fitness index of each fault repair task is the integration of its external and internal indexes,which is compared among different fault tasks to obtain the optimal task allocation strategy. Simulation is carried out for IEEE 33-bus system and the simulative results verify the effectiveness and practicality of the proposed strategy.
