Method, device, medium, equipment and wind power generating set for yaw-to-wind correction

Abstract

The invention discloses a method, a device, a medium and equipment for correcting yawing wind, and a wind generating set. The method comprises the steps of receiving real-time operating data from thewind generating set, wherein the operating data comprises an instantaneous wind speed value at a current moment sensed by the wind generating set; calculating a current wind speed of a position on which the wind generating set is located based on the real-time operating data received from the wind generating set; searching a yawing wind deviation value corresponding to a wind speed section to which the calculated current air speed belongs from prestored history yawing wind deviation values, and using as the yawing wind deviation value at the current moment, wherein a history yawing wind deviation value is stored in each wind speed section; and sending a yawing wind correction value corresponding to the searched yawing wind deviation value to the wind generating set, and correcting yawing wind at the current moment of the wind generating set.

Description

technical field [0001] The present invention relates to the field of wind power generation, more specifically, to a method, device, medium, equipment and wind power generating set for yaw-to-wind correction. Background technique [0002] For wind turbines, the inaccurate yaw of the generator set against the wind will reduce the power generation efficiency of the wind turbine generator and increase the load of the generator set at the same time. There are many factors that cause the yaw of wind turbines to be inaccurate to the wind. For example, the turbulence generated when the impeller rotates. This is because modern large-scale wind turbines are generally downwind units, so the wind vane is installed behind the impeller and behind the impeller. Under the effect of turbulence, the wind vane may not be able to accurately measure the free-flow wind direction at the impeller plane. In addition, human factors may also cause the yaw alignment of wind turbines to be inaccurate. ...

Problems solved by technology

However, the current software methods often use a uniform correction value for each wind turbine to perform yaw-to-wind correction, without considering that the yaw-to-wind deviation of the wind turbine may be different in different wind speed ranges, and also does not consider Under complex terrain conditions, the yaw-to-wind deviation of the crew also varies in different sectors, resulting in low accuracy of yaw-to-wind correction

In addition, the yaw-to-wind correction value of a single wind turbine calculated by some current software methods is often preset in each wind turbine. Override or manual configuration update, however, due to the cumbersome configuration of wind turbine parameters, it is difficult to achieve regular automatic update and unified management of wind turbine control parameters
