Abstract: The present subject matter is directed to a system and method for operating a wind turbine. More specifically, the system and method determines a dynamic cut-in wind speed for the wind turbine based on one or more environmental conditions. In one embodiment, the method includes providing a predetermined cut-in wind speed for the wind turbine based on at least one estimated environmental condition for a wind turbine site; determining one or more actual environmental conditions near the wind turbine for a predetermined time period at the wind turbine site; determining a variance between the at least one estimated environmental condition and the one or more actual environmental conditions; calculating a dynamic cut-in wind speed based on the variance; and, operating the wind turbine based on the dynamic cut-in wind speed so as to increase wind turbine operational efficiency.

Abstract: A control method for a wind power generating system includes the following procedures. When a rotational speed control condition is satisfied, a wind turbine is switched to operate under a rotational speed control mode to limit the electricity power by a maximum power point shifting manner. When a speed of an external wind is greater than a predetermined wind speed, the wind turbine is switched to operate under a safety mode to decrease a rotational speed of the wind turbine by a maximum torque extraction manner to protect the wind power generating system. A wind power generating system is also disclosed herein.

Abstract: An upwind wind turbine includes a tilting coupling mechanism configured to couple base end portions of blades to a hub such that the blades can tilt between a normal position and a retracted position in which the blades are tilted in a downwind direction relative to the normal position. The upwind wind turbine also includes a tilting drive operating in association with the tilting coupling mechanism to switch the positions of the blades and a rotation stop to stop the rotation of the rotor. When the blades are switched to the retracted position, the rotation stop is actuated to stop the rotor in a predetermined rotational position in which the blades can tilt without interference with the tower, and the tilting drive is actuated to tilt the blades to the retracted position after stop of the rotation of the rotor.

Abstract: If blades have been struck by wind that has reached a power reduction start wind speed that is lower than a conventional cut-out wind speed at which torque acting on a main shaft reaches the torque limit, a wind turbine generator performs torque reduction control for causing the change in the torque when wind speed is higher than the power reduction start wind speed to be different from change in the torque when wind speed is lower than the power reduction start wind speed so as to prevent the torque from exceeding the torque limit at the conventional cut-out wind speed. For example, if the wind striking the blades reaches the power reduction start wind speed, the wind turbine generator sets the slope of change in torque lower than that before the power reduction start wind speed is reached. Accordingly, the wind turbine generator can reduce the load acting on a device and suppress a reduction in power even if the blades are struck by strong wind.

Abstract: A wind turbine generator system includes, in a nacelle mounted atop a tower, a main shaft that is coupled to a rotor head to which wind turbine blades are attached and that integrally rotates therewith, a gear box accelerating and outputting the rotation speed of the main shaft, a generator driven by the output of the gear box, and a controller that performs cut-out control during strong wind when a measured value from an anemometer is a predetermined level or more. The controller is configured to decide that the anemometer has a fault when a difference of a predetermined level or more occurs between the measured value from the anemometer and an estimated wind speed value obtained from a relationship between a blade-pitch-angle of the wind turbine blades and an output of the generator.

Abstract: Reduction in power output or rotor speed of a wind turbine above a defined limit value, the reduction not being implemented based on the measured wind speed, but on an input value which on one hand is easily detected physically and by control technology and on the other hand is a good indicator of mechanical stresses on the wind turbine. The invention uses the rotor-blade angle as the input value in a manner that starting at the limit value, the reduction in power output or in rotor speed is adjusted as a function of the rotor-blade angle.
