Abstract

The embodiment of the invention provides a closed-loop control method and device for a wind power plant and a computer readable storage medium. The closed-loop control method comprises the following steps of calculating a preliminary optimal yaw angle of each fan in the wind power plant under different incoming flows through an engineering wake flow model of the wind power plant; measuring field wake flow data of the wind power plant; and correcting the initial optimal yaw angle of each fan under different incoming flows based on the field wake flow data of the wind power plant as feedback. Therefore, the wake flow influence between the fans can be reduced, and the annual energy production of the whole wind power plant is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wind power, and in particular to a closed-loop control method and device for a wind farm, and a computer-readable storage medium. Background technique [0002] With the gradual depletion of energy sources such as coal and oil, human beings pay more and more attention to the utilization of renewable energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. For coastal islands, grasslands, pastoral areas, mountainous and plateau areas that lack water, fuel, and inconvenient transportation, the use of wind power generation according to local conditions is very suitable and promising. Wind power refers to the use of wind turbines to convert the kinetic energy of wind into electrical energy. In recent years, wind farms have been widely developed and applied. [0003] However, offshore wind farms, especially large-sca...
