    • 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.
    • 根据特性曲线的风力发电厂的转速和俯仰控制/调整方法,其特征在于,在部分负荷运转中,在第一部分中的部分负荷运转下将转矩调整到第一规定转速 在第二部分中,在第三部分的满载操作下,将转矩从第一转速调节到第二转速,转子叶片的至少一个间距被调整为大于第二转速的转速 在第四部分中,如果先前已经根据第三部分执行了控制,则在第四部分中调节对于低于第二转速的旋转速度并大于第三转速的间距,并且在部分加载操作中 第五部分,如果先前已经根据fou进行了控制,那么针对低于第三转速的转速来调节转矩 第r部分。
