Wind alignment device of wind turbine generator and wind alignment method of wind alignment device

Abstract

The invention discloses a wind alignment device of a wind turbine generator and a wind alignment method of the wind alignment device, and belongs to the field of yaw logic design for wind turbine generators. The wind alignment device comprises an anemoscope used for detecting the wind direction, a positioning clamp, alignment windows, a bracket and a multifunctional laser leveling instrument, wherein the anemoscope is installed on the positioning clamp, the middle of the positioning clamp is arranged to be of a cylindrical structure, the anemoscope is located in the cylindrical structure, themiddles of the two sides of the cylindrical structure are each provided with a center parting line, the alignment windows are arranged on the center parting lines, reflective strips of the N pole andthe S pole of the anemoscope correspond to the alignment windows respectively, a groove is formed in one end of the positioning clamp, the other end of the positioning clamp is connected with the bracket, and the multifunctional laser leveling instrument is installed on the bracket. Following the sum-up of lots of practical experiences,, the groove of the device is formed in the middle of the positioning clamp, and the device is suitable for on-site installation and use; and the multifunctional laser leveling instrument is designed, and wind alignment is conducted by combining the mechanical structure and the alignment windows of the device. The device can meet the requirements of the wind turbine generator and has the advantages of high sensitivity and the like.

Description

technical field [0001] The invention relates to a wind-facing device and a wind-facing method for a wind turbine, and belongs to the field of yaw logic design of the wind turbine. Background technique [0002] Wind power generation is the most mature renewable energy power generation except for hydropower, and its installed capacity accounts for the vast majority of the total installed capacity of renewable energy power generation. [0003] The wind turbine includes a wind rotor and a generator; the wind rotor contains blades, hubs, reinforcements, etc.; it has the functions of rotating the blades to generate electricity by the wind, and turning the head of the generator. The wind power supply consists of wind turbines, towers supporting the generators, battery charging controllers, inverters, unloaders, grid-connected controllers, battery packs, etc. [0004] Yaw device: Turns the nacelle with the help of an electric motor so that the rotor is facing the wind. The yaw dev...
