AI Technical Summary

⚠Technical Problem

In existing technologies, when the wind vane fails, the wind turbine cannot obtain the wind direction, causing the equipment to stop operating, and the dual-redundant sensor solution increases the equipment and installation costs.

⚗Method used

By collecting the relative wind direction of each wind turbine unit from the wind vane, and when a faulty unit is detected, the absolute wind direction of the faulty unit is calculated using the preset geographical marker and the relative wind direction of the normal units, thus realizing wind direction acquisition and yaw control.

🎯Benefits of technology

Without increasing the cost of the wind vane, the system ensures that the wind turbine can operate normally when the wind vane fails, thus improving the reliability and operational stability of the wind turbine.

Abstract

This invention relates to the field of wind power generation technology, providing a method, apparatus, and machinery for wind direction acquisition and yaw alignment. The wind direction acquisition method includes: collecting the relative wind direction of each wind turbine unit measured by a wind vane; when a faulty turbine unit with a malfunctioning wind vane is detected, determining the absolute wind direction of the normal turbine unit relative to the geographical marker based on a preset geographical marker location and the relative wind direction of the normal turbine units; the normal turbine units are the wind turbine units other than the faulty turbine unit among multiple wind turbine units; and determining the absolute wind direction of the faulty turbine unit based on the absolute wind direction of the normal turbine unit. The wind direction acquisition method provided by this invention, when a wind vane fails, can obtain the absolute wind direction of the faulty turbine unit by performing geographical alignment calibration on the wind direction of the normal turbine units. This allows for normal wind direction acquisition even when a wind vane fails without increasing the cost of the wind vane, ensuring the normal operation of the wind turbine units.
