Embodiment
In order to make purpose of the present invention, technical scheme and creation characteristic clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of novel wind-solar complementary electricity generation system, comprise wind-driven generator, solar panel, storage battery, rectification circuit, DC/DC translation circuit, wind/light complementation controller, inverter, liquid crystal display, temperature sensor and air velocity transducer.Wind-driven generator is connected with wind/light complementation controller through rectification circuit; Solar panel one tunnel is connected with wind/light complementation controller through the DC/DC translation circuit, and another road directly is connected with wind/light complementation controller; Wind/light complementation controller also is connected with storage battery, liquid crystal display and DC load respectively; The input of inverter connects wind/light complementation controller, output termination AC load and AC network.Wind/light complementation controller is comprised of charging circuit, discharge circuit, amplifying circuit, testing circuit, protective circuit and DC/DC translation circuit, and they all are connected with the acp chip of wind/light complementation controller.Inverter is comprised of microprocessor, DC/DC converter, DC/AC converter and filter circuit, the input of DC/DC converter connects storage battery, output connects the DC/AC converter after circuit filtering after filtering, and the output of DC/AC converter connects AC load and AC network after filter circuit filtering.
The electricity that wind-driven generator sends is three alternating currents, become direct current after the rectification circuit rectification, testing circuit is detected the voltage of this direct voltage and storage battery, if this direct voltage meets charge condition higher than battery tension, through charging circuit, directly storage battery is charged; When if little this direct voltage of wind-force is weak, through the DC/DC translation circuit, adjusted, through charging circuit, charge a battery again, when storage battery being detected and be full of, wind/light complementation controller cuts off the charging of wind-driven generator to storage battery, and be switched to the electric energy that load resistance consumes the wind-driven generator generation, prevent the infringement of the no-load running of wind-driven generator to himself.By being arranged on the air velocity transducer on the wind power generation machine support; the signal of this transducer is given amplifying circuit through the A/D conversion and is nursed one's health; again through wind/light complementation controller acp chip analyzing and processing; the size of judgement wind speed; with the high wind speed of setting and minimum wind speed relatively; if, not within high wind speed and minimum wind speed, wind/light complementation controller cuts off wind-driven generator work, and wind-driven generator is protected.
Testing circuit is detected solar panel, and the electric energy transformed when solar panel meets charge condition higher than the electric energy of storage battery, through charging circuit directly to charge in batteries; When the electric energy that runs into the conversion of rainy weather solar panel is low, by the DC/DC translation circuit, adjusted, then through charging circuit, charge a battery.
When storage battery meets the condition of discharging, under the effect of discharge circuit, to DC load and inverter, discharged, the electric energy that DC load is directly used storage battery to provide, the DC inverter that AC load will provide storage battery through inverter becomes alternating current just can use, the microprocessor of DC/AC inversion control adopts the high performance DSP TMS320F28335 chip of TI company exploitation, its processing capability in real time is more powerful, and cost performance is high, switch frequency and performance that the assurance system is higher, at first the direct current of storage battery passes through the DC/DC converter in inverter, be adjusted into the direct current of 250 volts, by giving the DC/AC converter after filter circuit filtering, multi-channel PWM at microprocessor TMS320F28335 is controlled drive circuit, drive circuit reasonably drives conducting and the shutoff of IGBT in the DC/AC converter, the DC inverters of 250 volts are become to the alternating current of 50 hertz 220 volts, after filter circuit filtering for AC load, meet load and unnecessary electric energy is fed back to AC network simultaneously.
Wind/light complementation controller detects the voltage of storage battery by testing circuit, the operating state of storage battery is judged.The storage battery of at this, take one 24 volts describes as example, when the voltage of storage battery, during higher than protection voltage 29.4V, automatically cuts off the charging of storage battery is carried out to over-charge protective; When the voltage of storage battery falls when maintaining voltage 27.2V, to storage battery, adopt the PWM charging modes to carry out floating charge; When the voltage of storage battery during lower than recovery voltage 26.2V, close floating charge and enter all and fill.Storage battery overcharge impact that point voltage changes by ambient temperature greatly, temperature raises and overcharges point voltage and reduce, otherwise, overcharge point voltage and raise; Over-charge protective recovery point voltage and float charge voltage all have temperature-compensating; by temperature sensor collecting temperature signal; giving amplifying circuit through the A/D conversion is nursed one's health; again through wind/light complementation controller acp chip analyzing and processing; ambient temperature is judged, be as the criterion with 25 ℃ of fiducial temperatures, when every rising 1 degree of temperature; lead acid accumulator to 24V needs compensation-60mV, otherwise needs to compensate 60mV.Testing circuit is also detected the working condition of electric current and voltage, DC load and the AC load of the electric current and voltage of the electric current and voltage of solar panel, inverter direct-flow side, inverter AC, also has the signal gathered by air velocity transducer and temperature sensor, again after the wind/light complementation controller analyzing and processing, finally by liquid crystal display, these information are shown, understand timely the situation of system works for the user.
