Abstract

© 2018 IEEE. The more-electric aircraft (MEA) concept has become a major trend due to its multiple advantages. Many functions which are conventionally driven by pneumatic, hydraulic and mechanical power systems are replaced by electrical ones onboard MEA. This results in increased electrical power demand for MEA. Due to power off-take limit from high-pressure (HP) spool of an engine, extra power needs to be extracted from the low-pressure (LP) spool. Besides, recent studies have revealed that transferring power between LP and HP shafts in certain flight missions, like taxiing and descending will not only decrease fuel consumption but also increase compressor surge margins. This paper introduces an enhanced power generation centre for the MEA applications. It extracts power from both HP and LP spools, with each shaft is driving one electrical generator. These generators supply electrical power to a common DC bus through active AC/DC converters. Using the droop-control concept, the power sharing between LP and HP shafts can be smoothly controlled. Control method when power transferred from LP spool to HP spool is also presented. This architecture is built and simulated in the Matlab/Simulink environment. Simulations results including performances of electrical machines, power converters and engine under different scenarios are presented in this paper.
