    • The invention relates to a wind power plant, comprising a generator driven by a rotor in order to generate electrical power and a control means that comprises a pitch module for adjusting a pitch angle of blades of the rotor (2), and wherein the control means has an input for a required power reserve and determines a target pitch angle depending on an operating point of the wind power plant. The invention further relates to a secondary pitch controller, which comprises a detector (43) for available power and a dynamic offset module (44), wherein input signals for the available reserve power determined by the detector, the required reserve power and the generated electrical power are applied to the dynamic offset module, which is designed to determine a value for a pitch angle offset. An activation element (40) is further provided, which varies the target pitch angle by the pitch angle offset. Thanks to said link, in particular the variability of the pitch angle offset, the offset required for the desired controlling power can be determined taking into account the current working point of the wind power plant.

    • Disclosed is a wind power plant comprising a rotor that is equipped with pitch-adjustable rotor blades (4) and a central control device (55). Individual pitch devices (6) encompassing an adjusting drive unit (7), a communication link (56) to the central control device (55), and a regulator (60) is provided for adjusting the rotor blades (4). Said individual pitch devices (6) further encompass a fault detector which is configured so as to recognize abnormal operating states as well as a triggering mechanism that causes the respective rotor blade (4) to be moved into an off position. The invention allows the individual pitch devices (6) to self-sufficiently recognize a fault and react accordingly, the adjustment of the rotor blades (4) being monitored. The invention makes it possible to correctively intervene in the blade adjustment such that the wind power plant can be shut off as quickly and safely as possible, thus making it possible to minimize unfavorable conditions, especially great stress on the rotor blade (4) or the entire wind power plant. The adjusting movement of the rotor blades (4) can be varied according to the requirements, such as different wind speed, turbulence, or even air flowing against the blades at an angle.

    • The invention relates to a wind energy installation having a wind rotor (12), a generator (14) which is driven thereby and interacts with a converter (15) in order to produce electrical power, rotation-speed regulation (21) and converter control (25) which interacts therewith, wherein the rotation-speed regulation (21) outputs a nominal rotation speed signal (nref). Furthermore, additional regulation (3) is provided, which has an input (31) for an additional power and is designed to produce a rotation speed change signal therefrom, taking account of a rotator inertia moment, and to output this as an output signal, which is added to the nominal rotation speed signal via a logic element (29). Kinetic energy is taken from the wind rotor in a controlled manner by reducing the rotation speed and is converted by the generator (14) to additional electrical energy. This allows primary regulation power to be made available deliberately by rotation speed variation, to be precise even in unsteady wind conditions.
