At present, there are 10 types of small wind turbines according to their rated power, which are 100W, 150w, 200w, 300w, 500W, 1kw, 2kw, 3kw, 5kW, and 10kw. Its technical characteristics are: 2 to 3 blades, side-bias speed regulation, upwind direction, and high-efficiency permanent magnet low-speed generators. The unit runs smoothly, has reliable quality, and […]
The wind wheel is generally composed of blades, wheel valleys, cover plates, connecting bolt components and shrouds. The wind wheel is the most critical component of a wind turbine, which converts the kinetic energy of the air into mechanical energy. The wind wheel of most small wind turbines consists of 3 blades. The tip speed […]
Small wind turbines are suitable for areas where the annual average wind speed is above 3m/s, and the cumulative annual effective wind speed of 3~20m/s is above 3000h: the annual average effective wind energy density of 3-20m/s is above 100W/㎡. Small horizontal axis wind turbines generally consist of the following parts: wind wheel, generator, rotating […]
① Output characteristics of wind turbineThe torque produced by a horizontal-axis wind wheel with a fixed pitch varies with wind speed and rotation speed. If the rotation speed of the blade is too low, the blade will stall and the torque output by the wind wheel will decrease. Therefore, in order to obtain the maximum […]
The wind wheel of the vertical axis wind turbine does not adjust its direction with the change of the wind direction. The wind wheel of the vertical axis wind turbine rotates around a vertical axis, and the wind wheel axis is perpendicular to the wind direction. Its advantage is that it can accept wind from […]
A wind turbine whose installation position of the wind wheel axis and the horizontal plane is not greater than 15° is called a horizontal axis wind turbine. The wind wheel of a horizontal axis wind turbine rotates around a horizontal axis. The blades are arranged radially, perpendicular to the axis of rotation, and at an […]
①Basic structure of wind-solar complementary LED street lightWind-solar complementary LED street lights have the dual advantages of wind energy and solar products. When there is no wind energy, solar cell components can be used to generate electricity and the electricity can be stored in the battery. When there is wind energy and no solar energy, […]
The efficiency of a small wind turbine is very high, but it is not composed of a generator, but a small system with a certain technological content; wind turbine + controller + energy storage device. A wind turbine is composed of a generator, a rotating body, a tail, and a blade. Each part is very […]
Wind energy is the kinetic energy of the air, which refers to the energy carried by the wind. The magnitude of wind energy depends on the wind speed and the density of the air. The energy of the wind is converted from solar radiant energy. The energy radiated by the sun per hour to the […]
①The formation of windWind is a natural phenomenon. The horizontal movement of air on the earth’s surface is called wind. Wind is the air movement caused by the sun’s thermal radiation in the atmosphere on the earth’s outer surface. The uneven heating of the earth’s surface by solar radiation is the main cause of the […]
