Wind turbine yaw method and device, computer device, and readable storage medium

Abstract

The embodiment of the invention discloses a draught fan yawing method and device, a computer device and a readable storage medium, all of which are used for filtering the meaningless wind direction, avoiding draught fan yawing caused by the meaningless wind direction and achieving the purpose of draught fan yawing optimization. According to the embodiment, the method comprises the steps that the average wind direction of a wind power field within the current preset period is determined; whether the deviation angle of the average wind direction and the axis direction of a wind wheel of a wind power generator of the wind power field is located in the preset angle range or not is detected; if the deviation angle of the average wind direction and the axis direction of the wind wheel of the wind power generator of the wind power field is located in the preset angle range, whether the deviation angle is smaller than the preset angle or not is detected; and if the deviation angle of the average wind direction and the axis direction of the wind wheel of the wind power generator of the wind power field is not located in the preset angle range, yawing adjustment is conducted on the wind power generator according to the preset rule.

Description

technical field [0001] The present invention relates to the technical field of wind power, in particular to a wind turbine yaw method and device, a computer device, and a readable storage medium. Background technique [0002] Wind energy is constantly changing. As the wind direction changes, the wind turbine needs the yaw system to push and rotate to align with the wind direction. The yaw system of the wind turbine is also called the wind-facing device. Its function is that when the direction of the wind speed vector changes , can align the wind direction quickly and smoothly, so that the wind rotor can obtain the maximum wind energy. [0003] At present, the traditional yaw start-stop control of wind turbines is based on the angle between the current wind direction angle and the current normal of the rotation plane of the wind turbine as the judgment condition for starting and stopping yaw. However, under this control strategy, when the wind direction changes suddenly in a...

Problems solved by technology

However, under this control strategy, when the wind direction changes suddenly in a short period of time, the position of the wind turbine is turbulent, and the wind direction signal is wrong, the wind turbine will have large-angle yaw, frequent yaw, and wrong yaw in a short period of time. Air quality seriously reduces the power generation efficiency and safety reliability of wind turbines
