基于不同工作状态下的某型飞机蓄电池容量和负载分析

Battery capacity and electrical load analysis of an aircraft under different operating conditions

航空蓄电池在不同的飞行状态下可能成为电源或机上汇流条的负载,因而在分析飞机电气负载ELA的过程中,航空蓄电池的分析较为特殊。分析计算某型飞机蓄电池,完成飞机装载和准备阶段、应急情况下,蓄电池作为供电系统电源的容量分析;以及正常飞行阶段,蓄电池作为飞机交流汇流条重要负载的充电电流计算。计算方法不仅可用于飞机电气系统设计中的电瓶选型,而且为飞机电气系统加改装提供技术支持,也为后期对飞机电源系统和配电电网的ELA分析奠定了必要的技术基础。

Battery may become the power supplier or electrical load of the buses under different flight conditions,so battery analysis is much different when doing the aircraft electrical load analysis. The capacity analysis of an aircraft battery as supplier of power to the system during the loading,preparation and emergency period has been done. The charging-current calculation of the battery as a load of the ac bus during the normal operation has been completed as well. The analysis method can not only be applied to the selection of battery configuration in aircraft design,but also provide technical support for aircraft electrical system modification. The study lays necessary technical foundation for further ELA of aircraft power supply system and power distribution network.
