Background technology
At present, generally convert solar energy into electrical energy by solar panels and deposit accumulator in and be applied, and MPPT(Maximum Power Point Tracking is set, MPPT maximum power point tracking between accumulator and solar panels) controller, to reach maximum power output.But, do not consider the direction of illumination of sunshine, solar panels are generally fixing, therefore with sunshine between incident angle seldom can be vertical, so the output power of solar panels can also improve.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of photovoltaic energy storage control system is provided, by rotating solar panels, so that solar panels are as far as possible towards sunshine, and the difference according to different time sections illumination, formulate different standards and rotate solar panels, thereby so that the output power of solar panels further improve.
The technical scheme that realizes above-mentioned purpose is:
A kind of photovoltaic energy storage control system, comprise for the solar panels that receive sun power, be used for the accumulator of store electrical energy and be connected to MPPT controller between this accumulator and the solar panels, described photovoltaic energy storage real-time control system also comprises the microprocessor of the electric current and voltage presupposed information that stores each time period, be connected to voltage sensor and current sensor between described solar panels and the microprocessor, connect described solar panels and control the motor of this solar panels left rotation and right rotation, the timer that is connected to the motor driver between described motor and the microprocessor and connects described microprocessor, wherein:
Described voltage sensor and current sensor gather respectively voltage signal and the current signal of described solar panels output, and pass to described microprocessor;
The moment that described microprocessor provides according to described timer, 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, according to comparative result output control signal to described motor driver;
Described motor driver orders about described electric machine rotation according to the control signal that receives or stops operating.
The beneficial effects of the utility model are: the utility model is on traditional photovoltaic energy storage system-based, incident angle from sunshine and solar panels, increase can drive the motor that solar panels rotate, and the difference according to different time sections illumination is formulated different standards, gathering electric current and voltage information and standard information compares, rotation by the control motor so that solar panels as far as possible towards sunshine, thereby so that the output power of solar panels further improve.The utility model is simple in structure simultaneously, is easy to realize.
Description of drawings
Fig. 1 is the structural representation of photovoltaic energy storage control system of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, photovoltaic energy storage control system of the present utility model, comprise for the solar panels 1 that receive sun power, the accumulator 3 that is used for store electrical energy, be connected to the MPPT controller 2 between this accumulator 3 and the solar panels 1, store the microprocessor 4 of the electric current and voltage presupposed information of each time period, 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 to 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 MPPT computing, electric current and voltage accumulators 3 chargings of Maximum Power Output;
The electric current and voltage presupposed information of described each time period refer to the time according to month and 24 hours system be divided into each time period, at 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 be divided into 12 months with 1 year, i.e. 12 large 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, namely one day 8 minor time slices, a large time period and a minor time slice are combined into a time period, different electric current and voltage values is set in different time sections, is a time period such as 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 more accurate;
In the moment that microprocessor 4 provides according to timer 9, 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, export control signal to motor driver 8 according to comparative result; 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 to motor driver 8, and motor driver 8 drive motor 7 rotate, and drive solar panels 1 rotation; If described voltage signal and current signal are more than or equal to default 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, so that solar panels 1 stop operating, after default a period of time, readjust the position of solar panels 1; When described voltage signal and current signal always less than default 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 the situation of voltage signal and current signal maximum, by sending control signal so that motor driver 8 rotate by control motor 7, allow solar panels 1 rotation to a position, so that the voltage signal and the current signal that gather respectively at this position voltage sensor 5 and current sensor 6 are maximum, voltage sensor 5 and current sensor 6 stop to gather, then voltage sensor 5 and current sensor 6 continue to gather after default a period of time, thereby continue to regulate the position of rotation of solar panels 1, make it as far as possible towards sunshine, thereby so that the output power of solar panels 1 further improve.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that do not break away from the utility model scope, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
