Description
Technical field
The utility model relates to the solar electric power supply system technical field, specifically is meant a kind of hybrid power supply solar electric power supply system.
Background technology
Street lamp is the critical facility of urban construction, to city illumination and city are attractive in appearance the effect of not replacing is arranged.Current, the street lamp in most cities utilizes the network system power supply, therefore street lamp has occupied the urban electric power resource, bring pressure for industry and household electricity, for this reason, it is street lamp power supply, road lamp power supply that a lot of cities attempt adopting the solar cell energy storage plate, and purpose is rationally to utilize solar energy resources, reduces street lamp and takies industry and household electricity.
Existing solar energy storage system applied solar energy cell panel receives and the savings solar radiant energy, again solar radiant energy is converted to electric energy to street lamp power supply, road lamp power supply, but because geographical, inside even from weather, it is less that solar panel obtains solar radiant energy, for example when night, cloudy weather or rainy season a little less than the solar radiation, be unfavorable for solar panel savings solar energy, make solar energy storage system can't be continuously street lamp power supply, road lamp power supply, cause the street lamp cisco unity malfunction, this also is the reason that solar powered street lamp is difficult to obtain penetration and promotion.Certainly, the technical staff can be a street lamp power supply, road lamp power supply to obtain sufficient solar radiant energy by increasing the solar panel area, increases the weight of power supply cost on the one hand but increase the solar panel area, is unfavorable for device security and attractive in appearance on the other hand.
Summary of the invention
The problem that the utility model need solve provides the hybrid power supply solar electric power supply system of the round-the-clock power supply of a kind of energy.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of hybrid power supply solar electric power supply system, comprise a solar module and a connected DC-DC transducer, the one DC-DC transducer is connected in control cabinet, storage battery and the controller that is used to control accumulator cell charging and discharging are installed in the control cabinet, and described control cabinet also is connected with fuel cell by the 2nd DC-DC transducer.
As further technical optimization, above-mentioned control cabinet also is connected with and is used for the Soc manager of management and control fuel cell to charge in batteries.
Further, above-mentioned control cabinet is provided with the 3rd DC-DC transducer that is used for the control load electric current.
Preferably, above-mentioned fuel cell is a proton exchange fuel cell.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is except adopting the solar module power supply, also realize hybrid power supply by connecting fuel cell, can be in solar radiation more weak or do not have to be continuously charge in batteries under the situation of solar radiation, thus guarantee that solar electric power supply system can be round-the-clock powers for power consumption equipment.
2, control cabinet of the present utility model is provided with and is used for the Soc manager of management and control fuel cell to charge in batteries, the staff can be provided with the minimum accumulator electric-quantity warning line of fuel cell to charge in batteries by the Soc manager, fuel cell charges automatically to storage battery when accumulator electric-quantity is lower than this minimum electric weight warning line, this had both ensured preferential use solar energy, the electric weight of timely postcombustion battery when solar energy is under-supply again, realize that the solar electric power supply system power supply is uninterrupted, effectively prolong solar electric power supply system useful life simultaneously.
Description of drawings
Fig. 1 is the utility model embodiment schematic block diagram.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1, present embodiment discloses a kind of hybrid power supply solar electric power supply system, it comprises a solar module and a connected DC-DC transducer, the one DC-DC transducer is connected in control cabinet, storage battery and the controller that is used to control accumulator cell charging and discharging are installed in the control cabinet, the one DC-DC transducer solar module is used for stablizing the electric current and the voltage of solar module, and provides stable electric current and voltage to storage battery.Control cabinet is connected with fuel cell by the 2nd DC-DC transducer.Fuel cell is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that a kind of chemical energy that will be present in fuel and the oxidant is converted into electric energy, by in that to connect fuel cell on the control cabinet can be in solar radiation more weak or do not have to be charge in batteries under the situation of solar radiation, realize hybrid power supply, thereby guarantee that solar electric power supply system can round-the-clockly be the power consumption equipment power supply.Wherein the fuel of fuel cell can be the fuel gas of using always, fuel cell is selected proton exchange fuel cell for use in the present embodiment, proton exchange fuel cell is to utilize hydrogen to produce a kind of battery of electric energy, hydrogen is clean fuel, environment friendly and pollution-free during use, and hydrogen can obtain by the method for electrolysis, is a kind of renewable resource, therefore no matter consider that from the energy supply and the feature of environmental protection it all is preferred using proton exchange fuel cell.During use,, hydrogen gas tank is placed the street lamp below ground, filled a hydrogen and get final product in about 2 years for the external hydrogen gas tank of proton exchange fuel cell.The 2nd DC-DC transducer is used for the electric current and the voltage of smooth combustion battery, and provides stable electric current and voltage to storage battery.
Control cabinet also is connected with and is used for the Soc manager and the three DC-DC transducer that be used for control load electric current of management and control fuel cell to charge in batteries in the present embodiment.The staff is provided with the minimum accumulator electric-quantity of fuel cell module to charge in batteries by the Soc manager, fuel cell module charges automatically to storage battery when accumulator electric-quantity is lower than this minimum electric weight, this had both ensured preferential use solar energy, the electric weight of timely postcombustion battery when solar energy is under-supply again, realize that the solar electric power supply system power supply is uninterrupted, effectively prolong solar electric power supply system useful life simultaneously.Usually the minimum electric weight warning line of storage battery is set to 30% of accumulator electric-quantity, also promptly when the Soc manager detect accumulator electric-quantity less than total electric weight 30% the time, it is street lamp power supply, road lamp power supply that proton exchange fuel cell is started working to charge in batteries.Certainly, another of Soc manager done the time spent when street lamp turn-offs, and control fuel cell and solar module are charge in batteries simultaneously, and when charge in batteries reached normal electric weight, fuel cell was closed in the control of Soc manager.The 3rd DC-DC transducer is used to control the accumulator load electric current, ensures that storage battery provides stable electric current and voltage for street lamp, avoids excessive street lamp and the battery device of also damaging of electric current, reaches the fail safe that improves this electric power system, increases the service life.
This hybrid power supply solar electric power supply system can also be used for family or public electricity-using facilities such as solar water heater except being used to street lamp power supply, road lamp power supply.
The foregoing description is the preferred version that the utility model is realized; and indefiniteness is exhaustive; the utility model can also have other variations under same idea; need to prove; under the prerequisite that does not break away from the utility model design, any conspicuous replacement is all within the utility model protection range.
