METHOD AND DEVICE FOR REGULATING ANGLE OF DIAMETER STEP OF BLADES OF ROTOR OF WIND-POWER PLANTS

摘要

The invention relates to a method and a device for controlling the pitch angles of rotor blades on wind power stations, the pitch angle being controlled to maximize yields and prevent excess loads on the rotor blades. The aim of the invention is to maximize the propulsive power on rotor blades. Said aim is achieved by taking a first measurement of the pressure prevailing on the pressure side ( 5 ) and a second measurement of the pressure prevailing on the suction side ( 6 ) of a rotor blade ( 1 ), determining the difference in pressure between the first and second pressure measurement, and adjusting the pitch angle in accordance with the ratio between the first and second pressure measurement.
