Abstract:
Method for torque and pitch control/adjustment for a wind power plant according to the rotational speed according to a characteristic curve, in which at partial load operation in a first section the torque is adjusted up to a first predetermined rotational speed, at partial load operation in a second section the torque is adjusted from the first rotational speed up to a second rotational speed, at full load operation in a third section at least one pitch of a rotor blade is adjusted for rotational speeds greater than the second rotational speed, at full load operation, in a fourth section, the pitch is adjusted for rotational speeds lower than the second rotational speed and greater than the third rotational speed, if a control has been previously carried out according to the third section, and at partial load operation in a fifth section the torque is adjusted for rotational speeds lower than the third rotational speed, if a control has been previously carried out according to the fourth section.
