In this paper, a novel aircraft electrical power distribution system based on the distributed computer system is proposed. The principles, features and structure of the aircraft electrical power distribution system and the distributed computer system named electrical load management system (ELMS) are studied. The ELMS composed of four electrical load management centers (ELMCs) and two power source processors (PSPs) operates in the 1553B buses. Principles of the ELMCs and the PSPs are introduced. With the application of the distributed computer system, the aircraft electrical power distribution system is simple, adaptable and flexible.展开更多
永磁同步电机(PMSM)的起停以及频繁的速度变换,都会对多电飞机(more electric aircraft,MEA)电网电压形成冲击,进而影响飞机操作稳定性。在对比PMSM再生制动电能各种处理方法的基础上,为了提高多电飞机电网电压的稳定性,在机载直流配电...永磁同步电机(PMSM)的起停以及频繁的速度变换,都会对多电飞机(more electric aircraft,MEA)电网电压形成冲击,进而影响飞机操作稳定性。在对比PMSM再生制动电能各种处理方法的基础上,为了提高多电飞机电网电压的稳定性,在机载直流配电系统中接入电储能单元(electric accumulator unit,EAU),对所提出的三种不同拓扑结构进行对比。并依照所选的拓扑结构,在Matlab软件中建立含有储能单元的机载直流配电系统仿真平台。仿真结果表明,在直流母线中接入EAU能有效降低电网电压波动,提高供电效率。展开更多
