Abstract

The application discloses a wind measurement system, a wind measurement method, a yaw control method and a main control system. The wind measurement system includes: an ultrasonic wind measurement sensor, a position sensor and a data processor, wherein: the ultrasonic wind measurement sensor is installed on the impeller The position sensor is installed on any position that rotates synchronously with the impeller; the data processor is respectively connected with the ultrasonic wind sensor and the position sensor, and is used to obtain the ultrasonic wind sensor and the data measured by the position sensor, and determine the wind direction and wind speed at the real-time position of the ultrasonic wind sensor according to the acquired data, and the wind measurement results can more truly reflect the wind direction and wind speed around the wind power generating set.

Description

technical field [0001] The present invention relates to the technical field of wind power, and more particularly, to a wind measurement system, a wind measurement method, a yaw control method and a main control system. Background technique [0002] The wind measurement system, the yaw system and the main control system are important components of the wind turbine (referred to as "fan"). Upload to the main control system; one of the tasks of the main control system is to generate a yaw command and send it to the yaw system when the wind direction change is detected; the yaw system is used to control the nacelle of the fan to the left according to the received yaw command Or yaw to the right to face the wind, so as to ensure that the impeller of the nacelle can always be aligned with the wind direction and improve the power generation efficiency of the fan. It can be seen that whether the wind measurement results can truly reflect the wind direction and wind speed around the ...
