The operation principle structure of the honourable electric complementary electric supply installation of employing photovoltaic MPPT maximum power point tracking function as shown in Figure 5 in this base station intelligent accummulator constant temperature cabinet, it is by solar panel 32, wind-driven generator 36, MPPT maximum power point tracking (MPPT) photovoltaic controller 33, wind energy conversion system controller 37, intelligent controller 34, DC/AC inverter 35, the constant temperature cabinet controller 26 of band temperature sensor is formed, wherein the output of solar panel 32 and wind-driven generator 36 is connected to the input of intelligent controller 34 respectively through photovoltaic controller 33 and wind energy conversion system controller 37, the output of intelligent controller 34 connects through the input of DC/AC inverter 35 with constant temperature cabinet controller 26 successively, the output of constant temperature cabinet controller 26 respectively with small air-conditioning system 2,22 and each ventilating fan 4,20 and air intake fan 8,14 mains switch input connects, and the I/O end that discharges and recharges of intelligent controller 34 connects with the charging output/input of putting of batteries 3 simultaneously.Solar panel 32 generatings are to power to constant temperature cabinet by the photovoltaic controller 33 with MPPT maximum power point tracking function in the work, wind-driven generator 36 is also powered to constant temperature cabinet by wind energy conversion system controller 37, stresses to have the circuit design that MPPT maximum power point tracking is the photovoltaic controller 33 of MPPT function here.
Referring to Fig. 6~Fig. 9, MPPT maximum power point tracking (MPPT) photovoltaic controller 33 by voltage sampling circuit, current sampling circuit and in establish multiplier and comparator microcontroller form, the output of voltage sampling circuit and current sampling circuit passes to the input of microcontroller inner multiplication device, and the current power of multiplier output is the defeated input that is connected to intelligent controller 27 after the previous moment memory power with the microcontroller internal memory compares in comparator.MPPT volt controller is the vitals in the solar cell power generation system, under the external condition of determining, variation along with load, the solar battery array power output also can change, but exist a maximum power point and with maximum power point correspondent voltage and electric current, when operational environment changes, particularly when day illuminance and variation of ambient temperature, the output characteristic curve of solar battery array also changes thereupon, maximum power point correspondingly also changes thereupon, MPPT is the variation of detection arrays output state at any time, judge the position of maximum power point according to the control strategy of intelligence, adjust the operating voltage of array and follow the tracks of maximum power point voltage, realize the function of MPPT thus.Therefore the MPPT photovoltaic controller is not only a high efficiency DC/DC transducer, the control system of an intelligence especially, and it can make the power output of solar battery array increase about 19%~35%.Fig. 7 illustrates the photovoltaic controller control strategy, photovoltaic controller need sample timely and accurately storage battery current charging voltage and charging current, both multiply each other through multiplier and obtain current charge power, entering comparator with the memory charge power of previous moment compares, regulate the PWM duty ratio, thereby the control photovoltaic cell always works in maximum power point.In the hardware designs theory structure shown in Fig. 6, because the output characteristic of photovoltaic cell is non-linear, and the conversion amplitude is bigger, so use single-ended flyback converter (inverse-excitation type switch power-supply), this converter adds isolating transformer by buck-boost converter deduces, direct current output can be provided simply efficiently, wherein microcontroller adopts the MC68HC08SR12 microprocessor, use the output current and the output voltage of A/D module samples power supply, then regulate the PWM duty ratio, finally realize the maximum power output of photovoltaic cell.The effect quality of MPPT control strategy depends on directly whether the sampling of voltage and current is accurate.Fig. 8 illustrates the voltage sampling circuit of this photovoltaic controller, and it adopts optocoupler PC817 and three-terminal voltage-stabilizing pipe TL431 to match.TL431 is a kind of voltage-stabiliser tube able to programme, and when the secondary output voltage UOUT of transformer changed, the output voltage of optocoupler changed thereupon, and A/D can sample current charging voltage.Fig. 9 illustrates the current sampling circuit of this photovoltaic controller, by it the voltage at sampling resistor Rsam two ends is sampled, and uses differential type operational amplifier LM358 amplification to output to the A/D sampling end of MCU, thereby obtain the current value in the main circuit.Because signal demand is accurately sampled, and and isolated from power, linear optical coupling HCNR200 therefore used.The electricity consumption of single-chip microcomputer and peripheral circuit can be directly isolated transformation by storage battery and be obtained in addition, and system need not external power source, and is very convenient.Because the variation of sun light intensity and ambient temperature is a process slowly, so parameter sampling need not high real-time, every a few second once sampling can meet the demands.It is adjustable producing the time interval of interrupting, and the initial stage is shorter, can approach maximum power point rapidly; Later stage is longer, and anti-locking system vibrates near maximum power point.Disconnected for anti-locking system erroneous judgement, each control ratio all carries out 3 times result when consistent, just implements corresponding control strategies, otherwise resampling compares, and has so just guaranteed the normal operation of system to greatest extent.
In the practical application structure of the present invention, it is the device of JTLTK4820 that intelligent controller 34 can adopt model, it is the device of KEDA48V300 that DC/AC inverter 35 can adopt model, it is the device of JTLHWG4810 that constant temperature cabinet controller 26 can adopt model, and it is the device of JTLFK4820 that wind energy conversion system controller 37 can adopt model.
