Description

Blade Self-protecting wind electricity generating system
Technical field
It the utility model is related to power field, more particularly to wind electricity generating system.
Background technology
Wind energy is inexhaustible, nexhaustible clean energy resource, and wind-powered electricity generation is the major way for utilizing wind energy now, and it has The advantages of saving, be green, environmentally friendly.Therefore wind-power electricity generation receives the extensive attention of countries in the world.
The principle of wind-power electricity generation is to drive blade of wind-driven generator rotation using wind-force, then by booster engine by rotation Speed lifting promotes electrical power generators, and the formula of wind driven generator output power is as follows:
P = 1 2 C p ρ AV 3
In formula,
P:The power output of wind-driven generator;
Cp:Power coefficient;
ρ:Atmospheric density;
A:Blade swept area;
V:Wind speed.
According to the formula of wind driven generator output power, the power output of wind-driven generator and the cube of wind speed are into just Than, illustrate that the change of wind speed has a great impact for the power output of wind-driven generator, while the output work of wind-driven generator Rate is directly proportional to blade swept area, therefore the size of blade swept area can also produce to the power output of wind-driven generator Influence.According to present wind generating technology, about 3 meters per second of gentle breeze wind speed can starts to generate electricity, but wind speed is not By manual control, in the case where wind speed is excessive, power output overload easily occurs for wind-driven generator, it is therefore desirable to new skill Art makes wind-driven generator to keep a relatively stable power output under different wind speed.Such as Chinese invention patent application Number CN201410240163.7 discloses a kind of blade of wind-driven generator for automatically adjusting front face area, and the two panels for including top is lived Movable vane piece, the fixation blade of root, the electric hinge of connection moving vane and fixed blade, installed in the top of fixed blade and The hollow member being arranged between two panels moving vane, in addition to air velocity transducer on the wind-driven generator tower frame and with Computer is the electric hinge control system of carrier.But the blade adjustments of the patent have certain hysteresis quality, not prompt enough.
Account for main flow in wind power plant at present is horizontal axis wind-driven generator.Compared with horizontal axis wind-driven generator, Vertical axis aerogenerator have do not have to wind direction, it is noiseless, low advantage is required to wind field;But there is also starting wind velocity simultaneously High, the complicated, shortcoming such as wind energy utilization is low.These shortcomings all govern the application and development of vertical axis aerogenerator.
Many improved vertical axis aerogenerators are found by patent searching storehouse, this kind of wind-power electricity generation function passes through certain Mechanical device come the automatic windward side for changing fan blade, be greatly lowered the threshold wind velocity of vertical axis aerogenerator, from And wind energy utilization greatly improved.But the problem of they are present is:They are generally using gear, chain, connecting rod, hydraulic pressure system The mechanisms such as system, single-chip microcomputer change the windward side of fan blade, and structure is relatively complicated, production, cost of installation and maintenance phase Should be higher.Change blower fan automatically as Chinese invention patent application number CN201410227033.X discloses vertical axis aerogenerator The blower fan structure of blade windward side, including:Fan shaft, fan blade axle, fan blade, stopping means.Fan blade axle and wind Limited location device on arbor, makes fan blade axle rotate scope of the control at 90 degree, and the slewing area of fan blade is perpendicular to Horizontal plane is to parallel to horizontal plane.The blade adjustments of the patent are more inflexible, can not fundamentally solve wind-force it is big when blade Impaired problem.
