Embodiment Construction

[0038] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0039] figure 1 A flowchart showing a control method of a wind power plant according to a first exemplary embodiment of the present invention.

[0040] refer to figure 1 , in step S101, the inclination angle of the top of the tower of the wind power generating set is obtained.

[0041] As an example, the obtained inclination angle may only indicate the inclination angle of the top of the tower in the lateral direction.

[0042] As an example, the inclination angle of the tower top may be measured by an inclination sensor, and the measured inclination angle of the tower top may be read from the inclination sensor.

[0043] In step S102, based on the obtained tilt angl...

Abstract

The invention provides a control method and equipment of a wind generating set. The control method comprises the steps that the inclination angle of the top of a tower of the wind generating set is obtained; determining an additional variable pitch angle of each blade of the wind generating set based on the obtained inclination angle; and performing independent pitch changing based on the determined additional pitch changing angle so as to suppress lateral vibration of the tower. According to the control method and equipment, accurate tower lateral resistance increasing can be conducted through independent variable pitch based on the inclination angle of the top of the tower, and therefore lateral vibration of the tower is well restrained.

Description

technical field [0001] The present invention generally relates to the technical field of wind power generation, and more specifically, relates to a control method and equipment for a wind power generating set. Background technique [0002] The development of wind turbines is constantly moving towards large-scale, large-capacity, and offshore. For offshore wind turbines that often encounter unbalanced wind and waves, the lateral resistance of the tower can well suppress the lateral vibration of the tower without too much impact on the quality of power generation. [0003] At present, the lateral resistance of the tower is usually realized only based on the lateral acceleration of the tower, but in the process of realizing the lateral resistance of the tower, it is necessary to convert the lateral acceleration of the tower into the lateral vibration of the tower speed, and this step will often amplify the noise and deviation of the acceleration signal measured by the accelera...
