Embodiment Construction

[0045] figure 1 An embodiment of a wind turbine 100 is shown in a schematic perspective view. Wind turbine 100 includes a tower 102 , a nacelle 103 at the apex of the tower, and a rotor 104 operably coupled to a generator housed inside nacelle 103 . In addition to the generator, the nacelle also houses other components needed to convert wind energy into electrical energy, as well as various components needed to operate, control and optimize the performance of wind turbine 100 . The rotor 104 of the wind turbine includes a central hub 105 and a plurality of blades 106 extending outwardly from the central hub 105 . In the illustrated embodiment, the rotor 104 includes three blades 106, although the number may vary. Additionally, the wind turbine includes a control system. The control system can be placed inside the nacelle or distributed and communicatively linked at multiple locations inside the turbine.

Abstract

A method of controlling a wind turbine is provided. The method includes providing a primary power reference signal and a secondary power reference signal, the primary power reference signal is limitedaccording to a primary signal limit, and the secondary power reference signal is limited according to a secondary signal limit. The primary power reference signal and the secondary power reference signal are combined to provide a combined power reference signal, and the combined power reference signal is provided to a power or torque control system of the wind turbine.

Description

technical field [0001] The invention relates to a method of controlling a wind turbine using a combined power reference and a control system for a wind turbine. Background technique [0002] Modern wind turbines are usually variable speed turbines. In such turbines, power output is controlled by controlling the speed at which the blades can rotate, at least in certain modes of operation. For example, torque can be applied to the rotor to limit rotational speed during high winds. The rotor speed is controlled using a power controller or a torque control system such as an inverter. The power or torque control system is then controlled using a power reference signal typically generated by the turbine's main controller. As used herein, a power or torque control system may refer to a converter of a wind turbine, or to a power controller or a torque controller. [0003] The power reference signal may be generated based on the requirements of various control systems of the turb...
