Abstract
The utility model relates to a small off-net solar power station system, including solar energy batteries and a commercial power control switch. The solar energy batteries are connected with two mutual-alterable groups of accumulators through a charge/discharge control switch which is connected to a solar AC output end through an inverting control switch and an inverter, and is connected to a solar DC output end. The commercial power control switch capable of turning on/off the commercial power supply is connected in an AC 220v commercial power supply wiring. The control signal input parts of the charge/discharge control switch, the inverting control switch and the commercial power control switch are connected to a micro-computer control module. The system of the utility model can realize intelligent control for the charge/discharge process based on the user load state, thereby improving the capacity of solar energy and realizing uninterruptible power supply.
Description
Technical field
The utility model relates to a kind of off-grid small-sized solar power plant system.
Background technology
Solar energy generation technology is applied to family and remote area power supplies more and more, use is inconvenient, efficiency for charge-discharge is low, the defective of operation stability difference but existing small-sized solar Blast Furnace Top Gas Recovery Turbine Unit (TRT) ubiquity, its power supply does not realize that intelligent control is difficult to satisfy the instructions for use of remote area power supplies and average family routine～220V power supply simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is that providing a kind of can carry out intellectuality control to filling with electric process according to the user load situation, improves the storage capacity of solar energy, and realizes the off-grid small-sized solar power plant system of uninterrupted power supply.
Off-grid small-sized solar power plant system of the present utility model includes solar battery group, solar battery group discharges and recharges control switch through one and is connected with two groups of storage batterys that can switch mutually, discharge and recharge control switch and be connected to solar energy alternating current output, discharge and recharge control switch and also connect the solar DC output through inversion control switch and inverter; Also include in the system and be connected in the alternating current 220V mains-supplied circuit and city's electric control switch of may command mains-supplied switching; The described control signal importation that discharges and recharges control switch, inversion control switch and city's electric control switch all is connected in the system controlled by computer module, by its switching of system controlled by computer module controls.
The utility model has the advantages that:
1, by two group storage batteries is set, and to the charging process control of automaticallying switch, improve the storage capacity of solar energy, also avoided after charge in batteries is full of in traditional solar power system, solar components produces the defective of waste of energy in the wait process, improve efficiency for charge-discharge, also can prolong the useful life of battery.
2, can to carry out intellectuality control with electric process, can realize uninterrupted power supply according to the user load situation, improve solar powered stability and applicability greatly, help it and be widely used in the domestic consumer.
Description of drawings
Fig. 1 is the systematic schematic diagram of off-line type small-sized solar power plant system of the present utility model.
Embodiment
As shown in the figure, off-line type small-sized solar power plant system of the present utility model includes solar battery group 1, solar battery group discharges and recharges control switch 2 through one and is connected with two groups of storage batterys that can switch mutually 3, discharge and recharge control switch and be connected to solar energy alternating current output 7, discharge and recharge control switch 2 and also be connected to solar DC output 8 through DC control switch 6 through inversion control switch 4 and inverter 5; Also include in the system and be connected in the alternating current 220V mains-supplied circuit and city's electric control switch 9 of may command mains-supplied switching; The control signal importation that discharges and recharges control switch 2, inversion control switch 4, DC control switch 6 and city's electric control switch 9 all is connected in the system controlled by computer module 10, by its switching of system controlled by computer module controls.
The control method of said system is:
Gather sunlight with the solar energy component palette, produce electric energy, give the charging of first group storage battery, send indication by the system controlled by computer module after being full of fully and give second group of charging by charging-discharging controller by luminous energy;
When Control System of Microcomputer has detected the load connection by the induction installation in the electricity consumption loaded line, send instruction automatically and connect inversion control switch or DC control switch, power by first group storage battery;
When the first Battery pack voltage drops to set point, start the power supply of second group storage battery, when the second group storage battery voltage also drops to set point, start two group storage batteries parallel operation simultaneously;
When load is excessive when exceeding set point or accumulator electric-quantity when not enough, close storage battery, start city's electric control switch simultaneously, continue powering load by the mains-supplied circuit.
