At present, wind turbines have been developed for many years, basically forming two horizontal and vertical power generation modes. Most of the domestic wind turbines are horizontal wind turbines, especially high-power power generation systems are basically horizontal axes, mainly and manufactured. The level is related. Although such a device has a simple structure and a relatively high efficiency, the horizontal axis requires a wind-driven device, and the generator is placed at the top of the tower, so that the maintenance cost is relatively high, so the advantages of the vertical wind turbine are more obvious.
The power generation system in the vertical wind turbine is installed under the tower, and the overall center of gravity is low, which makes it easier to adapt to complex environments and large-scale. After all, installation and maintenance are convenient. And its blades rotate in a simple cylindrical shape, theoretically able to accept wind energy in all directions, without the wind device, the power generation should be higher.
Under normal circumstances, vertical wind turbines can generate electricity in a dozen turns, 200 rpm is already rated speed, general wind speed 1-28 m / s can generate electricity, low speed, will not affect the ecology, nor lubrication Oil; due to its small radius of rotation, it can save more space and accommodate more equipment.
Vertical wind turbines have very low wind resistance, and can work under 50m/s typhoon; its generator output curve is relatively hard, in the range of wind speed 5-9 m / s, the output of electricity should be It is about 20% higher than the horizontal axis; it is also simple to control, and it does not need to be suitable for the yaw system to drive the blade operation. It also includes a simple braking system.http://www.titanwindturbine.com/
