What Is a Cup Anemometer?

The wind cup anemometer used to measure wind speed is the wind cup anemometer. Its sensing part is composed of three or four conical or hemispherical empty cups.

The wind cup anemometer is the most commonly used wind measurement equipment in the test of power characteristics of wind turbines, and its measurement accuracy directly affects the test results of the fan power curve. According to the principle of wind speed measurement by wind cup anemometer, temperature will affect its measurement accuracy. Using the actual measurement data of wind turbine power characteristics, the influence of temperature on wind turbine anemometer measurement of wind turbine power characteristics was proved, and the method for correcting wind speed signals during the test in the new IEC wind power turbine power characteristics test standard was introduced. ^[1]

Application and Research of Wind Speed and Direction Sensor in Fan Control

The principle of measuring wind speed by various wind speed sensors is studied, the characteristics of wind speed measurement by various wind speed sensors are compared, and the requirements of wind power measurement for wind speed are analyzed. And through the error analysis of the wind speed measured by the wind cup anemometer, it is concluded that the use of a three cup wind speed sensor is more suitable for controlling wind turbines to generate electricity. A new method for processing wind speed data is proposed to make it better used for wind power control. It is of great significance to the development of wind power control technology. ^[2]

The wind cup anemometer is an extremely widely used wind measurement sensor, which has the advantages of large wind measurement range, high strength, and corrosion resistance. The wind cup of the three-cup anemometer currently used, the wind cup, is mostly determined through experience and experiments, and there is no perfect theoretical basis for guidance, so that there is no clear anemometer linearity (i.e. The linear relationship between the speed and the actual wind speed) are all affected by which parameters of the wind cup, the size of the specific impact and which parameters are the main influencing factors. In this thesis, by optimizing the wind cup geometry, slewing radius and other parameters, it is clear which parameters are affected by the anemometer's linearity and its dynamic response characteristics in order to design a wind cup structure with better linearity; at the same time improve the anemometer Dynamic characteristics in order to be able to measure wind speed more accurately and provide theoretical basis for the practical application and maintenance of three-cup anemometer. In this paper, the flow field simulation software ADINA is used to simulate the movement of the wind cup in the atmosphere. By changing the structure parameters of the wind cup, such as the radius of rotation and the diameter of the cup mouth, the movement characteristics of the wind cup in the atmosphere with different structural parameters are simulated. Based on the results, the influence of structural parameters on the dynamic and static characteristics of the wind cup is analyzed. Changchun Institute of Meteorological Instrument hopes to change the material and size of the existing EC9-1 anemometer cup cover to reduce its production cost. Its main purpose is to improve the dynamic and static characteristics of the anemometer. The dynamic and static characteristics of the anemometer are related to the moment of inertia of the anemometer rotating body. For this purpose, the moment of inertia of the wind cup is measured using the three-wire torsion method to verify the moment of inertia obtained by the Pro / E software. The dynamic and static characteristics provide the basis; at the same time, the wind cup structure parameters are changed, and the dynamic and static characteristics of the anemometer under different moments of inertia are obtained through wind tunnel experiments, and the simulation results are verified. ^[3]
