Abstract
The invention relates to a steady revolving speed type wind generator. The generator is driven by a group of turbines; the inside of the generator consists of a plurality of groups of independent rotors and stators; the groups of rotors and stators can generate power independently according to wind speed changes or generate power simultaneously; the numbers of rotors and stators working in the generator are determined according to different wind speeds; as the force required by a group of rotor and stator for cutting across the magnetic field is constant, the number of the groups of the rotors and stators in the generator is changed to change the force cutting across the magnetic field, so as to be adapt to the uncertainty of the wind speed. Therefore, the speeds of the turbines and the generator are not changed while the wind speed changes constantly.
Description
Affiliated technical field
The invention belongs to the wind-driven generator field, relate to generator designs.
Background technique
There is contradiction in present known wind-driven generator between the uncertainty of wind speed and generator speed need be stablized, have wind-driven generator at present now or do not control generator speed fully, allow it change with change of wind velocity, such wind-driven generator exists secondary speed too fast dangerous big, and generator efficiency is low; Also having a kind of wind-driven generator at present is to install speed reducer on generator additional, causes generator efficiency low like this, generator configurations complexity, rate of fault height.
Summary of the invention
Contradiction between the stability of the uncertainty that overcomes wind speed and generator speed makes the wind-driven generator energy conversion rate higher, reduces the wind-driven generator rate of fault; In natural wind speed changes, under the big or small constant situation of turbine,, change the required power of generator cutting magnetic field and then control secondary speed identical under different wind speed by changing generator power.
The designed technological scheme of the present invention is: wind-driven generator is made up of main shaft of one group of turbine, form by organizing independently generator in the generator more, the independent stator of many groups is fixed on the generator casing, organizes independent rotor more and is fixed on the main shaft and rotates simultaneously with main shaft; Wherein one group of generator work generating when wind speed is low, when wind speed accelerates, open another group generator work generating two generators work generating is so just arranged by control switch, the power of the cutting magnetic field that two generators work is required is big during than the work of one group of generator, and is identical when rotating speed that turbine and main shaft will be when wind speed accelerate and wind speed hang down like this; When wind speed becomes faster, open other many group generators work according to the size of wind speed again by control switch, so just can make turbine and main shaft under different wind speed with identical speed rotation work; When wind speed is slack-off, close wherein one group or several groups of generators by control switch again, the power of required cutting magnetic field diminishes during generator work like this, and the rotating speed when making turbine and generator can be with wind speed when wind speed is slow fast is identical.
The invention has the beneficial effects as follows: overcome all drawbacks of present wind-driven generator, improved wind power conversion efficiency, simple in structure, not fragile; Not making the rotor on turbine, main shaft and the main shaft of wind-driven generator simultaneously at wind speed can be that the output voltage of wind-driven generator is in metastable state with metastable speed operation.
Description of drawings
Be that the invention will be further described with example in conjunction with the accompanying drawings below.
Among the figure, 1. turbine, 2. generator casing, 3. main shaft, 4. generator amature, 5. generator unit stator, 6. generator lead wire, 7. control switch.
Embodiment
Turbine (1) is connected with main shaft (3) in the drawings, and main shaft (3) is made up of many groups independent generator rotor (4), is made up of many groups independent generator stator (5) in the generator casing (2); Control switch (7) was by one group of generator amature (4) in generator lead wire (6) the control generator casing (2) and generator unit stator (5) work generating when wind speed was low; When wind speed is accelerated, the suffered wind increases of turbine (1), turbine (1) and main shaft (3) faster rotational speed, at this moment control switch (7) is by another group generator amature (4) in generator lead wire (6) the control generator casing (2) and generator unit stator (5) work generating; One group in control switch when wind speed is slack-off (7) control generator amature (4) and the generator unit stator (5) quits work, it is identical when the rotating speed of turbine (1) is fast with wind speed when wind speed is slow like this, its output voltage is also identical, in like manner according to the difference of wind speed by generator amature (4) in the control generator casing (2) and generator unit stator (5) working quantity, the power of required cutting magnetic field and then reach the wind speed difference and the rotating speed and the generator output voltage of turbine (1), main shaft (3) are all identical when controlling generator work.
Claims (1)
1. stabilized (steady-state) speed type wind-driven generator, it is characterized in that: generator is made up of one group of turbine, main shaft and the independent rotor stator of many groups, rotor stator group number adapts to the power that different wind speed produces when changing generator work, and it is constant to reach under different wind speed turbine and generator speed.
