Abstract

The utility model relates to an off-grid control inverter of a wind-power generator. The off-grid control inverter includes a rectification and voltage-stabilization module, an inversion module and a transformer. The electricity generated by the wind-power generator is subjected to rectification and voltage stabilization by the rectification and voltage-stabilization module to form a direct current; the direct current is inversed into an alternating current by the inversion module and the alternating current is transformed to a voltage required by the transformer and then is outputted. An output terminal of the rectification and voltage-stabilization module is connected to a storage battery by a first switch element; and the storage battery is connected to the transformer by a second switch element and the rectification and voltage-stabilization module. By employing the off-grid control inverter of the utility model, the electricity generated by the wind-power generator forms stabilized voltage output by the voltage-stabilization module, the inversion module and the transformer; and a stabilized sine wave alternating current is outputted. According to the off-grid control inverter, the storage battery can be charged directly after the electricity being subjected to rectification and voltage stabilization or being transformed by the transformer and then rectified and outputted. The storage battery obtains a stabilized voltage and current and is prevented from being overcharged by a heavy current. The service life of the storage battery is significantly increased. When the storage battery is full charged, the storage battery is disconnected from the inverter.

Description

Wind-driven generator is from net control inverter
Technical field
The utility model relates to a kind of wind turbine power generation technical field, specifically, relates to a kind of wind-driven generator from net control inverter.
Background technology
Wind power generation is applied more and more extensive as a kind of clean energy resource.But wind-driven generator is owing to being subject to the impact of natural wind, its power generation performance is also unstable, can not directly use.Thereby the electricity generally wind-driven generator being sent is now first by charging a battery, and is then reverse into alternating current by inverter and uses, to reach stable Voltage-output.But, easily cause accumulator super-charge and damage.
Utility model content
The utility model provides a kind of wind-driven generator from net control inverter, by the exportable stable voltage of inverter.
In order to reach the object addressing the above problem, the technical solution of the utility model is:
A kind of wind-driven generator is from net control inverter, comprise rectifying and voltage-stabilizing module, inversion module and transformer, after wind turbine power generation, carry out rectifying and voltage-stabilizing by rectifying and voltage-stabilizing module and form direct current, direct current inversion after inversion module is alternating current, and alternating current fades to required voltage output through transformer.
Inverter as above, the output of rectifying and voltage-stabilizing module is connected with storage battery by the first switch element.
Inverter as above, storage battery joins by second switch element and rectification output module and transformer.
Inverter as above, inverter comprises control module, control module gathers wind power generation machine information, and controls the state of the first switch element and second switch element.
Inverter as above, is connected to solar power generation module between rectifying and voltage-stabilizing module and inversion module.
The utlity model has following advantage and good effect: the electricity that the utility model can send wind-driven generator forms stable Voltage-output by rectifying and voltage-stabilizing module, inversion module, transformer, the sine wave alternating current of stable output.After the utility model rectifiable voltage stabilizing, directly charge a battery, also can be by exporting to charge in batteries through over commutation after transformer transformation, stable voltage and current of accumulators, prevent that the large electric current of storage battery from overcharging, greatly improve the useful life of storage battery, in the time that storage battery is full of, storage battery and inverter disconnect.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model specific embodiment.
embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the wind-driven generator of the present embodiment comprises rectifying and voltage-stabilizing module, inversion module and transformer from net control inverter, wind-driven generator joins by circuit breaker DK and rectifying and voltage-stabilizing module, after wind turbine power generation, carry out rectifying and voltage-stabilizing by rectifying and voltage-stabilizing module and form direct current, direct current inversion after inversion module is alternating current, alternating current fades to required voltage output through transformer, by the sine wave alternating current of output winding 1 stable output.
Wherein, the output of rectifying and voltage-stabilizing module is connected with storage battery TC by the first switch element TK1.Storage battery TC joins by the output winding 2 of second switch element GT2 and rectification output module gq3 and transformer.
In addition, inverter also comprises control module, and control module gathers the electric current and voltage information of wind-driven generator, and controls the state of the first switch element TK1 and second switch element GT2.In the time that the electric current and voltage information of control module detection wind-driven generator is less than set point, the electricity that wind-driven generator sends is on the one hand by the sine wave alternating current of inverter stable output, control module control the first switch element TK1 closure on the one hand, second switch element GT2 disconnects, the direct accumulators TC charging of the direct current of regulator rectifier circuit output.In the time that the electric current and voltage information of control module detection wind-driven generator is greater than set point, the electricity that wind-driven generator sends is on the one hand by the sine wave alternating current of inverter stable output, control module control the first switch element TK1 disconnects on the one hand, second switch element GT2 closure, the alternating current that the output winding 2 of the transformer of inverter is exported is by the direct accumulators TC charging of rectification output module output direct current.When storage battery TC is full of after electricity, storage battery TC and inverter are disconnected,
Between rectifying and voltage-stabilizing module and inversion module, be connected to solar power generation module, the direct current that solar power generation module is sent exports transformer to after by inversion module inversion.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.
