Abstract

Embodiments of the present invention provide a method and system for controlling the pitch of a cluster of wind power generators, wherein the method includes: separately acquiring the preset number of blades of the first wind power generator and the second wind power generator within a preset time range Angle value, wherein the first wind generator and the second wind generator are located in the upwind direction of the target wind generator; according to the preset number of pitch angle values, determine the change trend of the pitch angle, and the blade angle of the first wind generator The delay time when the angle change trend follows the change trend of the pitch angle of the second wind power generator; the pitch control of the target wind power generator is performed according to the change trend of the pitch angle and the delay time. The wind power generator cluster pitch control method and system provided by the embodiments of the present invention overcome the disadvantages of low adjustment accuracy and pitch lag in traditional pitch control methods.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of wind power generation, and in particular to a method and system for cluster pitch control of wind power generators. Background technique [0002] At present, conventional energy sources such as coal, oil, and natural gas are not only limited in resources, but also cause serious air pollution. With the continuous acceleration of the world's industrialization process, energy consumption has gradually increased, and the global industrial hazardous material emissions have increased day by day, which has caused problems such as abnormal climate, increased disasters, and frequent occurrence of malignant diseases. Therefore, the development and utilization of renewable clean energy, especially the development and utilization of wind energy, has been highly valued by countries all over the world. [0003] With the continuous increase of the capacity of wind turbines, how to ensure the efficien...
