A kind of detection method of wind power generator

Abstract

The invention discloses a detection method of a wind power generator, which comprises the following steps: S1: place the generator on a fixed platform, and connect a current detection meter to the power transmission terminal of the generator; S2: install The first blade, at the first detection point, send air to the first blade at a fixed speed, and record the power generation of the generator; S3: at the second detection point, send air to the first blade at a constant speed, and record the power generation Generating capacity of the generator; S4: At the third detection point, send air to the first blade at a directional and constant speed, and record the generating capacity of the generator. The detection method of a kind of wind power generator of the present invention, under the situation of quantitative wind speed wind direction, by testing the impact of blades with different inclination angles and number of blades on the power generation of generators, the wind power generator adjusts the power of the blades according to the experimental parameters. The inclination angle and the number of blades make the rotating shaft rotate stably when the blades rotate, and reduce the unbalanced load of the rotating shaft of the generator on the basis of improving the power generation efficiency of the wind turbine.

Description

technical field [0001] The invention relates to the field of wind power detection, in particular to a detection method of a wind power generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. [0003] Existing wind power generators include: blades, shrouds, generators, nacelle covers, towers, tower bases and wind detectors. The wind force acts on the blades at a certain angle and speed, causing the blades to generate rotational torque and rotate, thereby converting wind energy into mechanical energy. The rotating blades will drive the generator on the tower to generate electricity, realizing the conversion of wind energy into electrical energy. [0004] During the working process of the wind turbine, the amount of wind energy captured by the wind turbine has a cubic relationship with the wind speed, and the angle between the rotation axis of the wind deflector and the wind di...

Problems solved by technology

[0004] During the working process of the wind turbine, the amount of wind energy captured by the wind turbine has a cubic relationship with the wind speed, and the angle between the rotation axis of the wind deflector and the wind direction also affects the efficiency of the wind turbine to capture wind energy; when the rotation of the wind deflector When there is an angle between the shaft and the wind direction, the efficiency of wind turbines to capture wind energy will be reduced. At the same time, when there is an angle between the rotation axis of the shroud and the wind direction, the deflected wind force will generate a wind turbine. Large eccentric loads reduce the service life of wind turbines
