摘　　要：针对飞机环形配电系统保护装置无法有效保护配电系统的问题,将方向闭锁纵联保护引入到飞机环网供电系统中。基于Matlab软件对飞机环网供电系统进行建模并故障仿真,并基于故障特征提出闭锁式方向纵联保护方法。仿真试验结果证明:该保护方法能实现环网故障时自动隔离,确保飞机配电系统的安全性,能有效提高飞机配电的可靠性。In view of the problem that the protective device of aircraft ring distribution system can’t effectively protect the power distribution system,the directional locking longitudinal protection is introduced into the power supply system of the aircraft ring-network.Based on the Matlab software,the aircraft ring-network power supply system is modeled and the fault is simulated.The directional locking longitudinal protection method is proposed based on fault characteristics.The simulation results show that the protection method can automatically isolate the faults of the ring-network,ensuring the safety of the power distribution system,and the reliability of the power distribution effectively.
