Abstract
The ultralow speed wind driven generator is a system comprising rotating disc, fixed disc, wind wheel blades, fixed wheel, vertical rod, collector ring disc, tiller, tail rudder and inverter. The rotating disc and the fixed disc constitute the power generating unit of the system and the inverter includes 50 Hz sinusoidal oscillator, shaper circuit, low voltage output circuit and inverting pull-push circuit. The power generating unit of the system can produce voltage even in very low speed of rotating blade, below 100 rpm. The present invention provides a new way for the utilization of weak wind resource.
Description
The present invention relates to a kind of wind-driven generator, especially a kind of ultra-low speed wind-driven generator.
The wind-driven generator of prior art, because of generator itself does not have the Ultra-Low Speed ride quality, so the wind-driven generator with this type of generator designs just can not adapt to the normal power generation at faint wind friction velocity, thereby limit promoting the use of in vast weak wind energy area.
Task of the present invention is to design a kind of surper-low-speed generator and can export the inverter of power frequency sine wave electric energy to load, thereby makes the wind power generating set that this surper-low-speed generator and inverter are housed, and can normally move under very low velocity and generate electricity.
This task is achieved in that basic structure pattern of the present invention is a system that is made up of rolling disc 1, fixed tray 2, wind wheel blade 3, stationary axle 4, upright pole 5, collector ring disc 6, rudder stock 7, tail vane 8 and inverter.The present invention has proposed to improve design to the main member of this system just, the one, adopt and form generator by rolling disc 1 and fixed tray 2, the 2nd, adopt and form electronic equipment by rectifier and inverter, guarantee to the stable 220 volts of Ac of power frequency sine wave of load output.
The rolling disc of described generator is a garden shape disk body, inlay the some monomer permanent magnets that become even number on it, leave equal gap between each magnet, so just constitute the rolling disc that a monomer permanent magnet is circumferentially arranged in the form of a ring along the garden dish, wind wheel blade is installed in the another side of this rolling disc.
Corresponding with the rolling disc of wind wheel, another fixed tray also is set in opposite directions, two dishes are alternate, leave certain air gap, and the inductor coil of some groups of ribbon cores is installed on the fixed tray, and the permanent magnet of inlaying on its coil quantity and the rolling disc equates.So be provided with, when wind promotion blade, when making the rolling disc rotation, the ring-shaped distributed permanent magnet of inlaying on it just forms a rotating magnetic field, and makes the inductor coil on the fixed tray of installing in opposite directions with it, because of cutting magnetic line produces induction current.This by the generator that rolling disc and fixed tray constituted, because of starting torque is little, even under faint wind friction velocity, fan blade also can drive turn disc, and from inductor coil output industrial-frequency alternating current.
This induction current becomes direct current and stores in the storage battery after collector ring is delivered to rectifier.When treating to power to the load, by inverter,, change 220 volts of Ac of power frequency sine wave into again with the direct current of storing in the storage battery.
Above-mentioned inverter is made up of following circuit, i.e. 50 hertz of sine wave generator that include hex inverter, scmitt trigger circuit, clamp down on that circuit and FM circuit constitute and shaping circuit, low-voltage output circuit, paraphase push-pull circuit and tracking circuit.
The working principle of this inverter is: by the direct current of introducing in rectifier or the storage battery, produce 50 hertz of alternating signals through oscillator, and by shaping circuit to waveform shaping, become normal form power frequency sine wave signal, again after paraphase and the amplification of the push-pull circuit rate of doing work, secondary by boosting transformer provides the sinusoidal wave power frequency of 240V-220V to load.
From the above, advantage of the present invention, the one, by the generator that rolling disc and fixed tray constitute, possess good ultralow run-up and press characteristics, for a difficult problem that solves weak wind generating has been opened up new approach.Use facts have proved, changes even blade rotational speed is lower than per minute 100, also can normal power generation.This advantage provides hope for the development and use of the vast gentle breeze area wind resource of China; The 2nd, the electric energy that this generator produces for the sinusoidal wave power frequency electricity of normal form, can satisfy the requirement of different loads characteristic, is fit to various household electricity devices and uses; The 3rd, generator does not follow conventional rotor, stator structure, and iron core does not have fluting, does not have armature winding yet, so complete machine structure is simple and easy, compact, safety firm, it is reliable to operate steadily, easy-maintaining, long service life.
