摘　　要：电力物资的及时有效供应是灾变后电网能快速恢复供电的基本保障,科学合理的电力物资调配能够极大的缩短事故恢复的时间、提高电网运行的安全性及事故的处理效率。根据事故后电力物资需求的特点,利用对称三角模糊数模拟应急活动中的不确定性因素,引入物资供给时间的保障率指标,确定有物资调配时限的最优路径。在此基础上,以最大程度地恢复电网输电能力为目标建立多物资储备点、多物资需求点的电力物资调配方案的数学模型,并用算例验证了方法的有效性及正确性。The effective and timely supply of power material is the basic guarantee for quickly service restoration after a disaster.Scientific and rational allocation of power material could greatly reduce the time of recovery,and increase the safety of power grid and the efficiency in handling the accident.Triangular fuzzy number was used to simulate the uncertainties in the emergency response activities.Based on the characteristics of demand for power material,the optimal path with time limits is determined by the guarantee rate of time for material supply.And a mathematical model of emergency power material allocation program for multi-material reserves and multi-material needs was established to achieve the goal of maximizing total transfer capability of the grid.Examples proved the efficiency and validity of the proposed approach.
