Description
Technical field
The utility model is relevant with lifting-force type vertical-axis wind power generator group, espespecially a kind of system that can drive lifting-force type vertical-axis wind power generator group to start under lower wind speed state.
Background technique
At present, along with the pressure of energy and environment increases, this clean environment firendly of wind energy, and the energy more and more comes into one's own cheaply, and along with the development of technology, vertical axis aerogenerator group has low noise because of it, unlike the impeller of horizontal axis wind-driven generator, need to rotate along with wind direction advantages such as wind, is subject to people and more and more pays close attention to.
Wherein lifting-force type vertical-axis wind power generator group is widely used owing to having higher wind energy utilization efficiency.The lifting-force type vertical-axis wind power generator group of greater efficiency generally has higher tip-speed ratio and lower solidity.Here, tip-speed ratio refers to the roulette speed of blade and the ratio of wind speed; Solidity refers to the planimetric area of all blades on blade rotary swept surface and the ratio with blade rotary swept area.
But the solidity of the lifting-force type vertical-axis wind power generator group of greater efficiency is generally all lower, its aerodynamic characteristic has determined under a certain wind speed, if its rotating speed is lower than can carry out certain speed stage below the rotating speed of peak output conversion time, it has a minimum wind-drive torque.Particularly under lower wind speed, surface friction drag torque and the generator electromagnetic resistance torque sum of all bearings that this minimum driving torque likely connects lower than this speed stage wind-driven generator group wind-wheel, cause the wind wheel of wind power generating set can not cross this compared with slow-speed of revolution section, thereby can not realize the wind energy conversion of greater efficiency.So, after lower solidity vertical axis aerogenerator group its wind wheel in the time of low wind speed can not state of rest from the beginning starts progressively to accelerate to higher speed under the driving of wind-force, obtain higher driving torque more wind energy is converted to mechanical energy.If the External Force Acting not except wind-force, wind power generating set need to be under the effect of a higher wind speed vs, continues generator operation could be voluntarily from static Acceleration of starting to higher rotating speed.But in fact need only wind speed on a certain minimum windspeed vmin, and have the external force except wind-force to drive wind power generating set accelerated service to exceeding a certain minimum operation rotation speed n min, vertical axis aerogenerator can generate electricity in continuous running, and vmin will be much smaller than vs.Therefore, do not take the startup wind speed of the lower solidity lifting-force type vertical-axis wind power generator group that drives measure higher, its application has obtained restriction.
For head it off, some lifting-force type vertical-axis wind power generator groups adopt the blade of higher solidity, and its individual blade chord length is longer, and blade number is more, so that vertical axis aerogenerator group can just can be started under low wind.But because its blade material increase makes blade cost higher, when high wind, cross section is larger windward, and the wind-force of the substantially horizontal that blade is subject to makes a concerted effort to increase, and causes shaft tower and given tensile load to increase, thereby make shaft tower and basic expenditure of construction increase, economic benefit is not good.
In addition, also have some lifting-force type vertical-axis wind power generator groups to adopt generator having no iron core, make the electromagnetic resistance torque of generator less, thus total drag torque of lifting-force type vertical-axis wind power generator group also reduce, thereby can under low wind speed wind-force state, just can start.But generator having no iron core efficiency is lower, and capacity is little, and cost is high, heat radiation difficulty, reliability is poor, has limited the overall generating capacity of wind power generating set.
Therefore, how making lifting-force type vertical-axis wind power generator group can overcome drag torque and start under compared with low wind speed state, is the problem of solution that the industry is needed badly.
