Wind power detection method of wind power generator

Abstract

The invention discloses a wind power detection method of a wind power generator. The wind power detection method comprises the following operation steps that firstly, a power generator is placed on afixing table, and the power transmission end of the power generator is connected with a current detection meter; secondly, a first paddle is arranged on a rotation shaft of the power generator, air issupplied to the first paddle in an oriented and fixed-speed manner at the first detection point, and the power generating capacity of the power generator is recorded; thirdly, air is supplied to thefirst paddle in an oriented and fixed-speed manner at the second detection point, and the power generating capacity of the power generator is recorded; and fourthly, air is supplied to the first paddle in an oriented and fixed-speed manner at the third detection point, and the power generating capacity of the power generator is recorded. According to the wind power detection method of the wind power generator, through testing of influences of paddles different in dip angle and blade number on the power generating capacity of the power generator under the situation of the fixed wind speed and the fixed wind direction, the power generator adjusts the dip angle and the blade number of the paddle according to experiment parameters, the rotation shaft is driven to stably rotate when the paddlerotates, and the deflecting load of the rotation shaft of the power generator is reduced on the basis that the power generation efficiency of the wind power generator is improved.

Description

technical field [0001] The invention relates to the field of wind power detection, in particular to a wind power 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 ...

Problems solved by technology

[0005] In the prior art, the wind detector usually includes a wind vane and an anemometer, and uses the wind vane and the anemometer to detect wind parameters such as wind direction and wind speed. The wind detector is installed on the nacelle cover behind the impeller. Only after reaching the wind detector, wind parameters such as wind speed and wind direction all change, so the wind speed and wind direction and other wind parameters obtained by the wind detector have low accuracy and large errors
