Background technique
Wind-driven generator is divided into horizontal axis and vertical shaft two big classes.Large-scale wind electricity equipment is based on horizontal axis at present.But, when large-scale horizontal axis wind-driven generator develops into 1MW or above power, near current material intensity, design and manufacturing limit.As: large-scale horizontal axis wind-driven generator setting height(from bottom) surpasses 100 meters, and the cost of device fabrication, engineering construction and maintenance is huge.It needs expensive accurate dynamically balanced blade, accurate yaw system, stressed huge feather speed control system and the pylon of consumption lot of materials etc.Because setting height(from bottom) is very high, makes that the equipment wind loading rating is very poor, installation difficulty is very big, and installation cost is very high; Owing to the requirement of tip-speed ratio makes the operating noise of equipment very big.Compare with horizontal axis wind-driven generator, vertical axis aerogenerator does not need expensive blade, accurate yaw system, stressed huge feather speed governing and the systems such as pylon of consumption lot of materials, and can adapt to any wind direction, setting height(from bottom) is low, operating noise is little, and starting wind velocity requires low.So vertical axis aerogenerator more and more is subjected to industrial investment people's attention in recent years.
The blade rotational speed of vertical axis aerogenerator was slower in the past, and conventional method is to adopt to increase the requirement that blade area satisfies the collection wind energy.In order to obtain bigger power, the turning radius of blade will be increased, just to obtain the blast kinetic energy that bigger moment of torsion can obtain to be needed.But, along with the increase of power, carry blade or support the method for individual blade with roller with vertical shaft, all can't bear because of power continues the material weight that increases, also can't satisfy the structural strength requirement of cantilever structure increase.
In sum, guaranteeing under the condition of enough blowing areas how to guarantee that vertical axis aerogenerator can bear bigger wind and carries structure along with the increase of power, not have the better way of solution so far yet.
Summary of the invention
