某型飞机负载分配均衡性研究

Research on the Balance of Load Distribution of a Certain Type of Aircraft

飞机供电分为供电系统和配电系统两大类,配电系统主要将飞机115V电压通过电路转换来满足不同的用电设备需求,配电系统的可靠性和稳定性直接影响到整个飞机的用电安全,并对整个使命任务的成功执行起到关键性的作用。随着现代飞机用电设备的逐渐增多,任务的逐渐加重,供配电系统也越来越复杂,同时供电系统的容量需求也越来越大,对飞机配电系统的配电质量和均衡性要求变得越来越高。为提高发电机并联供电时负载分配均衡性,以运X飞机分布式环形配电网络为背景,将该型飞机配电系统中任意两台发电机作为研究对象,研究当两台直流发电机分组并联时的负载分配均衡性条件,并找出影响负载分配均衡性条件的可能因素,进而找到能够解决问题的方法。

Aircraft power supply is divided into two categories:power supply system and power distribution system. The power distribution system mainly converts the 115 V voltage of the aircraft through electric circuits to meet the needs of different power equipment,the reliability and stability of the power distribution system directly affects the safety of the whole aircraft,and plays a key role in the successful implementation of the mission. With the increasing number of modern aircraft electrical equipment,the increasing task,the power supply and distribution system is becoming more and more complex,and the power supply system’s capacity demand is also increasing,the requirement of power distribution quality and balance for aircraft power distribution system is becoming higher and higher. In order to improve the load distribution balance when the generators are connected in parallel,taking the x aircraft distributed ring distribution network as the background,taking any two generators in the aircraft distribution system as the research object,this paper studies the load distribution equilibrium condition when two DC generators are grouped and connected in parallel,and finds out the possible factors that affect the load distribution equilibrium condition,and then finds out the method that can solve the problem.
