摘　　要：电力系统供电不足时,可以切除过量的负载以保证系统的稳定性.针对飞机电力系统供电不足的情况,提出一种最优负载切除方法.该方法考虑了飞机上关键负载的优先供电要求,将负载优先级权重因子引入负载方程中,把负载切除问题转换为多目标优化问题.通过求解该优化问题,克服了负载切除的随机性和盲目性,满足了关键负载的优先供电要求.实验结果验证了所提出的负载切除方法的正确性和有效性.When power supply is insufficient in power system, the system stability can be warranted by shedding the excess loads. An optimal load shedding method is proposed for power supply shortage on the aircraft electric power system. The load shedding problem is formulated to the multi-objective optimization problem. The load weight priority factor is introduced into the load equation. To solve the optimization problem, the blindness and randomness of load shedding are avoided and the power supply priority of the vital loads is satisfied. Experiment results show the correction and effectiveness of the proposed method.
