The invention has the beneficial effects as follows: the present invention is on traditional photovoltaic accumulator system basis; Incident angle from sunshine and solar panels; Increase can drive the motor that solar panels rotate, and formulates different standards according to the difference of different time sections illumination, gathers electric current and voltage information and standard information and compares; Rotation through the control motor makes solar panels as far as possible towards sunshine, thereby makes the output power of solar panels further improve.The present invention simultaneously is simple in structure, is easy to realize.
Description of drawings
Fig. 1 is the structural representation of photovoltaic energy storage control system of the present invention.
Embodiment
To combine accompanying drawing that the present invention is described further below.
See also Fig. 1; Photovoltaic energy storage control system of the present invention; Comprise the solar panels 1, the accumulator 3 that is used for store electrical energy that are used to receive sun power, be connected MPPT controller 2 between this accumulator 3 and the solar panels 1, store the electric current and voltage presupposed information of each time period microprocessor 4, be connected to voltage sensor 5 and current sensor 6 between solar panels 1 and the microprocessor 4, connect solar panels 1 and control the motor 7 of this solar panels 1 left rotation and right rotation, the timer 9 that is connected the motor driver 8 between motor 7 and the microprocessor 4 and connects microprocessor 4, wherein:
The electric current and voltage of 2 pairs of solar panels 1 of MPPT controller carries out corresponding M PPT computing, electric current and voltage accumulators 3 chargings of Maximum Power Output;
The electric current and voltage presupposed information of described each time period be meant with the time according to month and 24 hours system be divided into each time period, at all predefined electric current and voltage value information of each time period, for example: because weather is different throughout the year; Sunshine is also different; So 1 year was divided into 12 months, i.e. 12 big time periods, be divided into per 3 a hour minor time slice by 24 hours systems the every day in each middle of the month; Promptly one day 8 minor time slices; A big time period and a minor time slice are combined into a time period, and the different voltages with different current value is set in different time sections, are to be a time period like the 9:00-12:00 of some day in August; Certainly, can divide more specifically, for example the electric current and voltage value in each time period of every day of every month is all different, and is more concrete just accurate more;
In the moment that microprocessor 4 provides according to timer 9,, export control signal to motor driver 8 according to comparative result with the voltage signal that receives and current signal and this electric current and voltage presupposed information size relatively of time period of living in constantly; That is, if the electric current and voltage value that described voltage signal and current signal were preset less than its time period of living in, microprocessor 4 outputs are rotated control signals and are given motor driver 8, and motor driver 8 drive motor 7 rotate, and drive solar panels 1 rotate; If described voltage signal and current signal are more than or equal to preset electric current and voltage value of its time period of living in; Microprocessor 4 outputs stop operating control signal to motor driver 8; Motor driver 8 orders about motor 7 and stops operating; Make solar panels 1 stop operating, after preset a period of time, readjust the position of solar panels 1; When described voltage signal and current signal always less than preset electric current and voltage value of its time period of living in; And solar panels 1 have rotated 360 when spending; Microprocessor 4 is chosen voltage signal and the maximum situation of current signal, makes motor driver 8 rotate through control motor 7 through sending control signal, lets solar panels 1 rotate to a position; Make the voltage signal and the current signal maximum of gathering respectively at this position voltage sensor 5 and current sensor 6; Voltage sensor 5 stops to gather with current sensor 6, and voltage sensor 5 continues to gather with current sensor 6 after preset a period of time then, thereby continues to regulate the position of rotation of solar panels 1; Make it as far as possible towards sunshine, thereby make the output power of solar panels 1 further improve.
