Abstract

This paper investigates a variable speed constant frequency power generation system based on induction generator for a three-phase four wire system in more electric aircraft (MEA) applications. In the proposed scheme, the induction generator is driven by the shaft of an engine. The generator output is connected to an active rectifier with a dc link capacitor. The engine also drives a permanent magnet generator (PMG), the output of which initially charges the dc link capacitor to the desired voltage level. The dc voltage is converted to constant frequency constant amplitude ac voltage for three-phase four-wire loads of the aircraft using a four-leg inverter. In this paper, a flux optimization-based vector control strategy for the induction generator with power factor improvement is investigated. Also, the overload capability and transient performance of the induction generator in a MEA architecture is presented.
基于感应发电机的多电动飞机发电系统
本文研究了一种基于感应发电机的三相四线制变速恒频发电系统。在所提出的方案中,感应发电机由发动机的轴驱动。发电机输出与带有直流链路电容的有源整流器相连。发动机还驱动一个永磁发电机(PMG),其输出最初将直流链路电容器充电到所需的电压水平。使用四脚逆变器将直流电压转换为飞机三相四线制负载的恒频恒幅交流电压。本文研究了一种基于磁链优化的功率因数改进异步发电机矢量控制策略。同时,给出了感应发电机在MEA结构下的过载能力和暂态性能。
