How to control a wind turbine?

The most di cult area for controlling the turbine is the middle wind speed interval. In this interval the best e ciency of the turbine is achieved by running the generator at nominal speed PSfrag and replacements keeping the pitch angle at 1 . This is achieved by control the generator to stall with regulator model in Figure 3.21.

How fast does a wind turbine change at 2 seconds?

At the instant t = 2 seconds, the wind speed changes to 11.5 m/second, with this being the nominal wind speed, that is, the wind speed at which the turbine gives nominal power.

What is the speed control of a wind turbine?

The speed control of generator is performed to control the speed of the wind turbine. For each wind speed, there is an optimum point, that is, the optimal turbine speed for which the maximum wind power is captured. The information on this operating point is known from equation (1) ( Pesic, 1994 ).

How does a wind turbine controller work?

This controller adjusts the pitch angle reducing the power coefficient, and thus, the power extracted from the wind, when the rotational speed increases up to the rated speed. It maintains the optimal pitch angle when the generator speed is less than the rated speed, and thus, the wind turbine operates with optimum power efficiency.

How do rotor blades work in a high wind turbine?

For the high wind speeds the desired operation is to keep the turbine's power at the rated. This is achieved by regulation of the rotor blades pitch angles. As the pitch actuator has a performance limitation of _ max, on the ramping speed, this prevents fast control of the regulator.
