Control of a variable-speed variable -pitch wind turbine in the entire range of wind speed

The paper presents simulation results of regulating rotational speed, torque, generator electrical power and blade pitch angle of a wind power plant with a high -power VSVP (variable -speed variable -pitch) wind turbine over the full range of wind speeds. It was assumed that the only measured quantity was the rotational speed of the turbine. Difficulties in determining the correct reference generator torque in the zone close below the rated wind speed were found, leading to rapid changes in the generator torque and disturbances (growths and drops) in the generated power.
