You can see that the main current decreases, because the motor acts as a generator. Observe that the speed follows precisely the acceleration ramp.Īt time t = 1.9 s, the speed set point of the Brushless drive is changed to -500 rpm. The induction machine and the DC brush motor accelerate to nominal speed (the two mechanical loads are proportional to the speed of the motors).Īt time t = 1.4 s, the Brushless DC motor starts accelerating to the set point of 500 rpm.

The Generator Control Unit activates the primary contactor, which enables the AC power on the aircraft. There are also scopes inside the AC Power Generation, the Induction motor, the Brushless DC motor and the DC brush motor.Īt time t = 0 s, the engine accelerates from 0 rpm to 12000 rpm in 0.4 second.Īt time t = 0.3 s, the speed reaches the threshold of 9000 rpm. You can observe the AC and the DC measurements at the top level of the schematic. There are two resistive loads (heater and lamp) and a 300 W DC brush motor (motor driving a fuel pump). There is a 4 kW Transformer And Rectifier Unit (which supplies 28 Vdc), a 12 kW induction machine (motor driving a pump), a 1 kW resistive load (lamps) and a 3 hp simplified (using an average value inverter) brushless DC drive (motor driving a ballscrew actuator).įinally, the last section represents the DC loads. The fifth section represents the AC loads. It is represented by 4 circuit breakers with adjustable current trip. The fourth section represents the secondary Power Distribution system. Finally, a parasitic resistive load is required to avoid numerical oscillations.

There is also a 3-phase contactor controlled by the Generator Control Unit. It is composed of three current and voltage sensors. The third section represents the Primary Distribution system. The Generator Control Unit regulates the voltage of the generator to 200 volts line to line. The mechanical input of the modified machine of 50 kW is the engine speed.

It is composed of a modified version of the simplified synchronous machine. The second section represents the power AC generator. The first section represents the generator mechanical drive and is modeled by a simple signal builder, which provides the mechanical speed of the engine shaft. The system is composed of six main sections.
