Wind Turbine Part II: Build a Three-Shaft Gearbox for Higher Transmission Ratios

This example demonstrates a three-shaft gearbox.

It has a high transmission ratio to multiply the slow input shaft speed with high torques. It is the second part of the wind turbine assembly.

The initial positions and initial angles are calculated automatically to give a smooth start of the simulation. Power is applied to the slowest shaft, which means that the output shaft will have a much higher rotational speed.

Figure 2 shows the input and output shaft speeds. As seen, to get smoother performances while running the system, the input shaft is regulated by a PID controller.
