Abstract

In this study, a comprehensive model of variable-speed, constant-frequency (VSCF) aircraft electric power system (AEPS) with a large share of nonlinear loads is developed. The model is used to study the performance of the system under different nonlinear loading conditions. The performance of the VSCF AEPS is studied over the entire range of the aircraft electric power system operating frequency. Moreover, the model is extended to study the performance of the AEPS under nonlinear loading along with harmonic cancellation. Both transient and steady-state performance characteristics of the system are obtained and investigated. The effect of nonlinear loading on power quality of the AEPS is also investigated and compared to applicable aircraft electric power system´s IEEE and military standards.
