Parked

When the wind turbine is parked the generator is disconnected, the blades are pitched to feather and pitch brake is activated. Also, the drive shaft brake is activated to keep the rotor stationary.

In this scenario the aerodynamic induction calculation is typically disabled. However, the dynamic stall model is still active to capture the load variation due to changes in the angle of attack due to turbulent inflow and blade motion.

For simulations of a parked rotor, click the Parked button on the Control System screen and enter:

• the fixed pitch or aileron angle to be used when parked, and

• the rotor position or azimuth angle when parked (note that this position is used at the start of the simulation, but it is possible for the brake to slip, allowing the azimuth to change during the simulation). A zero azimuth angle means that the first blade is pointing vertically upwards.

Click Enable external controller if a user-defined controller logic is to be used.
