Behavioural Modelling of a Switched Reluctance Generator for Aircraft Power Systems

A system-level modelling technique for a switched reluctance generator (SRG) is described for aerospace applications. Unlike existing techniques, this model is very simple and only reproduces the average behaviour of the input-output variables that are required for system-level analysis of the aircraft power distribution system. The model is parameterised from the measured generator response, avoiding the need for a detailed knowledge of the equipment structure, which may be unavailable. The modelling procedure is described in detail and validated by measurements on a switched reluctance generator within an aircraft test facility.
