What new types of wind turbines are there?

Bladeless wind turbines should be the latest type.

The principle behind Vortex’s wind power generation is the Karman vortex effect in fluid dynamics, which refers to the fact that when a steady incoming flow bypasses certain objects under certain conditions, both sides of the object will periodically fall off. Dual-row linear vortices with opposite rotating directions and regular arrangement are produced. After nonlinear action, a Karman vortex street is formed. For example, water flowing through bridge piers and wind blowing through towers, chimneys, wires, etc. will form Karman vortices. Once the vortices are large enough, they may cause the structure to oscillate. Vortex takes advantage of this aerodynamic instability to maximize oscillation and capture mechanical energy, and then use this mechanical energy to generate electricity. Naturally, the design of this device is completely different compared to a conventional turbine. It mainly consists of a fixed mast, a generator and a hollow, lightweight and semi-rigid fiberglass cylinder on top. Vortex automatically changes stiffness and "syncs" with wind speed to maintain resonance without any mechanical or human intervention. Utilizing the vortex shedding effect for wind power generation is a technological leap forward in wind energy that will generate energy in a more efficient, cheaper, and more environmentally friendly way. The technology has attracted interest from Harvard University as well as SunEdison's TerraForm renewable energy division Power, Inc. and Dat Venture.

The significance of this wind measurement tower for wind power prediction is as follows:

The wind farm wind measurement tower plays a very important role in wind power prediction. important role. The function of the anemometer tower is to provide data support for the operation of wind turbines by measuring the wind speed and direction of the wind farm, and then predict the output power of the wind farm. Analyze historical data, establish a wind power power prediction model, and use current wind speed and other related parameters to predict the future output power of the wind farm.
