Description of drawings
Below with reference to accompanying drawings specific embodiments of the present invention is described in detail, in the accompanying drawings:
Fig. 1 shows solar power system structural representation according to an embodiment of the invention;
Fig. 2 shows controller schematic diagram according to an embodiment of the invention.
Embodiment
Fig. 1 shows solar power system structural representation according to an embodiment of the invention, comprising: solar panel 10, and being used for solar energy converting is electric energy; Controller 20 is used to control electric energy and load circuit 40 is powered and/or storage battery 30 is carried out charge/discharge, and the state of storage battery 30 and solar panel 10 is monitored, and monitor state information is sent to remote supervision module 50; Remote supervision module 50 is used for according to monitor state information controller 20 being carried out telemanagement;
Storage battery 30 is used for storing or discharging electric energy.
In the present embodiment, solar panel is the core in the solar power system, also is to be worth the highest part in the solar power system, and its effect is to be electric energy with solar energy converting, or is sent in the storage battery and stores, or drives loaded work piece; Controller is used to control the whole system operation state, and storage battery is played the effect of additives for overcharge protection, over, in the bigger place of the temperature difference, controller can also carry out the temperature-compensating energy, and when load circuit is the street lamp circuit, can also add other additional functions, as light-operated switch, time switch etc.; Storage battery (group) is generally lead-acid battery, its effect be when illumination is arranged with the electrical power storage that solar panel sent, it's time to needs to discharge again; State informations such as the solar panel that remote supervision module is gathered according to controller and the voltage of storage battery and temperature are carried out control and management at far-end to solar power system.
Present embodiment has been realized the intelligent recharge and discharge of solar power system, the state of storage battery can correctly be monitored and measure to this controller simultaneously, realize group-net communication by telecommunication technique, can concentrate remote monitoring to the state of system, realize real time on-line monitoring for node, thereby when system's generation problem, in time intervene, avoided the paralysis of solar power system.
Fig. 2 shows controller schematic diagram according to an embodiment of the invention, as shown in Figure 2, this controller is the control core based on central processing unit 101, peripheral module comprises solar-electricity plate interface 102, and charge-discharge control circuit 103, power inverter 104, state (as voltage, temperature etc.) collecting unit 105, output control circuit 106 and communication interface 107 constitute.
In the present embodiment, the voltage-current characteristic of solar panel has very strong non-linear, and promptly when sunshine, intensity changed, its open circuit voltage did not have too big change, but the maximum current that is produced has sizable variation, so its power output and maximum power point can change thereupon; Yet when luminous intensity one timing, the electric current of cell panel output is certain, can think constant-current source, and therefore, the solar panels interface circuit is match battery plate power output automatically, has improved the utilization ratio of solar energy.
To charge in batteries, usually the method that adopts be in the early stage, the quick charge in mid-term, recover the capacity of storage battery, adopt little electric current to replenish the electric weight that battery loses because of self discharge for a long time latter stage in charging; Battery discharging process incipient stage voltage descends very fast; Slow decline of voltage in mid-term and long time of continuity, after stage in the end, discharge voltage sharply descends, should stop discharge immediately, otherwise will cause irreversible damage by accumulators, therefore, the accumulator cell charging and discharging administration module can rationally be controlled accumulator cell charging and discharging, improve charge efficiency, increase the life-span of storage battery.
