Abstract

The invention discloses a wind measuring system and method, a yaw control method and a master control system. The wind measuring system comprises an ultrasonic wind measuring sensor, a position sensor and a data processor, wherein the ultrasonic wind measuring sensor is mounted on a flow guide cover of an impeller; the position sensor is mounted at any position where the position sensor can be rotated synchronous with the impeller; the data processor is correspondingly connected with the ultrasonic wind measuring sensor and the position sensor and is used for acquiring the data measured by the ultrasonic wind measuring sensor and the position sensor and determining the wind direction and wind speed under a real-time position of the ultrasonic wind measuring sensor according to the acquired data, wherein the wind measuring result can really reflect the wind direction and wind speed of the wind surrounding a wind-powered generator unit.

Description

technical field [0001] The invention relates to the technical field of wind power, and more specifically, relates to a wind measuring system, a wind measuring method, a yaw control method and a main control system. Background technique [0002] The wind measurement system, yaw system and main control system are important components of the wind turbine (referred to as "wind turbine"), among which: the wind measurement system is used to measure the wind direction and wind speed of the wind farm in real time, and the wind measurement results 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 a change in the wind direction 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 impellers of the nacelle can always be aligned with the wind direction and improve the ...
