Development of a simulation model for an aircraft electrical main generator

A new approach to the development of a simulation model for an aircraft electrical main generator is presented. In this approach, a recently developed physical voltage behind reactance modeling technique is used to efficiently and accurately separate the stator-rotor interactions of a synchronous generator in order to increase computational efficiency. This study describes the method used to develop a representative simulation model of a synchronous generator from hardware frequency-response testing, with additional generator controls analogous to built-in systems on an actual aircraft. Comparisons are presented between results from simulation tests and hardware testing using basic step load conditions.
