Abstract

The embodiments of the invention provide detection methods and devices for a wind direction azimuth angle and a wind turbine generator set. A detection method for the wind direction azimuth angle comprises the steps of measuring a relative wind direction angle in a preset cabin coordinate system through utilization of a wind indicator of the wind turbine generator set; obtaining a cabin azimuth angle of a cabin in an azimuth angle coordinate system according to a yaw angle of the wind turbine generator set and a cabin mounting angle in the preset azimuth angle coordinate system when the wind turbine generator set is mounted; and carrying out coordinate transform on the relative wind direction angle from the cabin coordinate system to the azimuth angle coordinate system according to the cabin azimuth angle, thereby obtaining the wind direction azimuth angle corresponding to the relative wind direction angle under the azimuth angle coordinate system. According to the scheme provided by the invention, the wind direction azimuth angle can be obtained through utilization of existing data of the wind turbine generator, so cost increase resulting from increase of detection equipment is avoided, and operation optimization and operation and maintenance management of a fan are facilitated.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a method and device for detecting wind direction and azimuth and a wind power generating set. Background technique [0002] In the wind power industry, generally, the wind direction rose diagram of aircraft locations can be used to understand the overall wind resources of the wind farm. The wind direction rose diagram is based on the percentage values ​​of various wind directions and wind speeds averaged in a certain area for many years, and is drawn according to a certain ratio. In the wind rose diagram, the data of wind direction and azimuth is very important. The wind direction and azimuth can not only provide input for advanced control algorithms of wind turbines, such as tower shadow control, noise control, etc., but also provide data for post-evaluation of wind farms, thus obtaining At the same time, operation and maintenance personnel and technical support personnel ne...
