摘要： A partial pitch wind turbine is described wherein the wind turbine blade has an inner blade section designed for stall-controlled operation and an outer blade section designed for pitch-controlled operation. The different blade profiles for the different sections allow for the efficient operation of the blade while providing for the control of the wind turbine to effectively reduce blade root moments. The outer blade sections can be pitched out of the wind to reduce root moments due to the outer blade sections, while the increasing power capture of the inner blade section maintains nominal power output.

摘要： A partial pitch wind turbine and an associated control method are described wherein the wind turbine blade comprises an inner blade section designed as a stall-controlled blade and an outer blade section designed as a pitch-controlled blade. During operation of the wind turbine, the outer blade sections are pitched out of the wind to reduce the lift force generated in the outer blade sections, thereby reducing the blade root moments due to reduced moment arms. Meanwhile, the inner blade sections continually produce increasing power output for increasing wind speed, thereby allowing for nominal power output to be maintained while effectively de-rating the outer blade sections.

摘要： A balancing method and system for a partial pitch rotor blade for a wind turbine is described. Balancing elements are mounted to the pitch system of the rotor blade, which remove the need for complicated balancing operations to be performed which may affect the structural stability of the rotor blade body. A method is described wherein a suitable compensating balancing weight for mounting to the pitch system may be used, the weight chosen based on the known tip and root weights of standard blade extender and rotor blade parts used.

摘要： A method of controlling the yawing of two-bladed wind turbine is described. The yaw speed of the turbine is increased when the wind turbine rotor blades are in a substantially vertical position, and the yaw speed may be reduced when the blades are substantially horizontal. By modulating the yaw rate based on the rotational angle of the blades, the effect of the yaw moments on the wind turbine structure is reduced, and the wind turbine may be designed to take into account such reduced forces.

摘要： A blade for a partial pitch wind turbine is described, wherein the blade has a truncated aerodynamic profile provided at the pitch junction of the blade. The truncated trailing edge acts to prevent the formation of a trailing edge gap during pitching between the trailing edges of the inner and outer blade sections of a partial pitch blade, thereby reducing the negative impact of air leakage, etc., when pitching a partial pitch blade.

摘要： A method for controlling the position of blades of a two-bladed wind turbine when extreme conditions are detected or forecast for the wind turbine. When extreme conditions are detected or forecast, the wind turbine blades are positioned in a horizontal arrangement, and actively yawed such that a tip of one of the wind turbine blades points into the wind direction. The blades are yawed such as to actively follow the changing wind direction, resulting in a reduced surface area of the blades exposed to the extreme wind forces, due to the spear-like arrangement of the turbine blades. This reduced surface area provides for a reduction in the extreme loads which may be experienced by the wind turbine in such extreme wind conditions.

摘要： A method for controlling a two-bladed pitchable swept-blade wind turbine in extreme wind conditions is described, wherein when extreme conditions are detected or forecast for the wind turbine, the wind turbine blades are pitched such that they will passively align in a substantially horizontal arrangement. The blades can be yawed such that a tip of one of the wind turbine blades points into the wind direction, resulting in a reduced surface area of the blades exposed to the extreme wind forces. This reduced surface area provides for a reduction in the extreme loads which may be experienced by the wind turbine in such extreme wind conditions.

摘要： A two-bladed partial-pitch wind turbine and a method of controlling such a wind turbine during high wind conditions are described. The turbine is operable to pitch the outer sections of the turbine rotor blades during extreme wind conditions (i.e. high wind loads) such that the outer blade sections are substantially orthogonal to the inner blade sections. This arrangement acts to reduce the extreme thrust loading experienced by the wind turbine structure during severe gusts (e.g. during hurricane or typhoon conditions), and accordingly reduces the risk of damage to the wind turbine in such conditions.
