Abstract

A model of the advanced aircraft electric power system is developed and studied under variable-speed constant-frequency (VSCF) operation. The frequency of the generator´s output voltage is varied from 400-Hz to 800-Hz for different loading case-studies. Non-linear DC loads in addition to the different passive and dynamic AC loads are included in the simulation of the VSCF aircraft electric power system. Power conversions are obtained using 12-pulse converters. Moreover, two high-pass passive filters are designed and compared according to their loss and effectiveness in reducing the harmonic contents of the generator output waveforms. The power quality characteristics of the studied VSCF aircraft electric power system are presented and the effectiveness of the proposed filters is demonstrated through compliance with the newly published aircraft electrical standards MIL-STD-704F.
