A kind of solar powered control systemTechnical field
The present invention relates to a kind of Application of Solar Energy control system.
Background technology
Solar electric power supply system can be divided into solar energy photovoltaic system, energy-storage system, using electricity system three part, the difference of lectotype selection, and a lot of scheme capable of being combined, comprehensive conclusion is divided into two schemes substantially, and one is AC system scheme, a kind of direct current system scheme.Wherein exchange program principle comprises: photovoltaic panel, voltage controller, charge and discharge electrical equipment, storage battery, inverter, electrical appliance.Its shortcoming is: 1, need adopt from net inverter, and three phase alternating current motor starting load is rated load more than 5 times, generally must add frequency converter; 2, the general charge and discharge cycle-index of storage battery about 300 times, storage battery can meet the useful life of 2 years to 3 years, and storage battery cost is high; If use plumbous carbon or lithium battery instead, use cost is higher; 3, system maintenance work amount is large, and storage battery need carry out a discharge and recharge detection half a year, which increases the maintenance of system; 4, system management inconvenience, storage battery needs to change for about 3 years, and brings many uncertain costs in use can to future.
Summary of the invention
The object of the invention is to provide a kind of solar powered control system for the above-mentioned defect of prior art, realizes solar energy stable power-supplying, and no longer need to use battery power storage through controlling power supply flow scheme improvements.
Technical solution of the present invention is: a kind of solar powered control system, comprises photovoltaic panel, charger, super capacitor, voltage controller, electrical appliance, intelligent controller, it is characterized in that: photovoltaic panel comprises generating photovoltaic panel and sunlight detects photovoltaic panel; Voltage controller comprises voltage controller 1, voltage controller 2; Generating photovoltaic panel one tunnel connects voltage controller 1, then is connected with electrical appliance; Another road connecting charger, super capacitor, voltage controller 2, then be connected with electrical appliance; Voltage controller 1 realizes direct current photovoltaic power supply; Voltage controller 2 is connected with super capacitor, and realizing powers to voltage controller 1 supplements, and namely realizes when solar power transient change making its steady operation to the stable power-supplying of electrical appliance; Intelligent controller connects photovoltaic panel, charger, super capacitor, voltage controller 2, electrical appliance; Realize detecting intensity of illumination to photovoltaic panel, control Charge Management, detect super capacitor discharge and recharge, the supplementary power of control voltage controller 2 pairs of electrical appliances, the load of controller electrical appliance and operation, realize power supply and coulomb balance, namely realize when the instant generated output of solar energy is large strengthening electrical appliance load, when the instant generated output of solar energy hour realizes reducing electrical appliance load.
The solar powered control system of further described one, is characterized in that: voltage controller is MPPT controller.
beneficial effect of the present invention is1, electrical appliance load can adapt to automatically according to sunray is strong and weak;
2, automatic control and adjustment feed system, electrical appliance is provided with load on and controls, and under intelligent controller controls, load follows solar energy change, initiatively moves control overhead and loads;
3, adopt super capacitor to replace storage battery, overcome the shortcomings such as the life of storage battery is short, maintenance cost is high, super capacitor is non-maintaining, and electric discharge can be permitted more than 1,000,000 times to reach, and normal service life can reach more than 12 years.
This system may be used for daily life processing as flour milling, squeeze rice, also can with drawing water, other use electric machining such as ore dressing, its use cost is significantly lower than the work system of diesel generation.
Below in conjunction with drawings and the specific embodiments, the present invention is further described.

Embodiment
In figure:solar energy flour milling system, electrical appliance adoptsa direct current flour milling machine, this programme comprises solar energy photovoltaic panel, charger, super capacitor, voltage controller, direct current flour milling machine, an intelligent controller; Equipments Setting major requirement:
1,load electricity consumption is calculated:flour milling two tons, flour milling machine needs work 7 hours;
2, solar energy photovoltaic panel:6KWh is pressed in generating every day of every KW solar energy, and 3.5KWh is pressed in rainy day generating.When solar power opens normal work at more than 1.5KW, Solar use efficiency can by 80% measuring and calculating, flour milling 2t/ days;
3, super capacitor:when sunlight is not enough, for ensure by flour milling machine clout grind, need super capacitor to provide regularly power, make whole system grind clout reliable shutdown;
4, voltage controller:voltage control module accomplishes that photovoltaic electric is preferential, when photovoltaic is not enough, takes super capacitor electric energy, carries out management to super capacitor discharge and recharge;
5, intelligent controllerrealizeintelligent management system manages flour milling feed system, can detect intensity of illumination, according to the start and stop grinding system of intensity of illumination; The data such as real-time display photovoltaic power, load power.
