Abstract
The utility model relates to the application of a photovoltaic generating system, in particular to application of a VRLA (Valve Regulated Lead Acid)-based storage battery in the photovoltaic generation system, which comprises a solar battery, a controller, a storage battery pack, an inverter, a direct current load and an alternating current load, wherein the solar battery is connected with the controller, the controller is connected with the storage battery pack, the inverter is connected with the controller, the direct current load is connected with the controller and the inverter, and the alternating current load is connected with the inverter. The VRLA-based storage battery has a clamping function to the working voltage of the solar battery, so that the loads are ensured to be near the most ideal working point.
Description
Technical field:
The utility model relates to the application of photovoltaic generating system, is specifically related to based on the application of VRLA storage battery in photovoltaic generating system.
Background technology:
In the photovoltaic generating system, generally use the open type lead acid accumulator in early days, but the open type lead acid accumulator has and need add acid and add water and safeguard that acid solution is prone to shortcomings such as contaminated environment, be unfavorable for that unattended operation uses and environmental protection as energy storage device.In the last few years, valve controlled sealed lead-acid accumulator (VRLA) enjoyed great popularity owing to sealing acid nonleakage, not corroding the equipment pollution environment, was used widely in industries such as China's telecommunications, electric power, railways.Present photovoltaic system is used storage battery, almost all is the VRLA storage battery.The main effect of VRLA storage battery has 2 points: under the situation such as (1) at night or cloudy and photovoltaic array production capacity and load electricity consumption be inconsistent, storage battery can be stored excess energy or to load energy is provided; (2) since the operating characteristic of solar module influenced by solar irradiance, temperature etc. very big, load usually can not be near the ideal operation point.
The utility model content:
The purpose of the utility model provides based on the application of VRLA storage battery in photovoltaic generating system, and it can solve existing problem in the background technology, and the operating voltage of solar cell is had clamping action, can proof load be near the ideal operation point.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises solar cell 1, controller 2, batteries 3, inverter 4, DC load 5, AC load 6; Solar cell 1 is connected with controller 2, and controller 2 is connected with batteries 3, and inverter 4 is connected with controller 2, and DC load 5 is connected in controller 2 and is connected with inverter 4, and AC load 6 is connected with inverter 4.
The utlity model has following beneficial effect:
(1) raising recycles the life-span.For prolonging the life-span that recycles of VRLA battery, grid alloy should be good in the corrosion layer conductivity of grid and reactive species interface formation, and grid should have creep-resistant property.Battery design adopts tight assembling, and suitably improves assembling pressure.
(2) improve the battery charge ability to accept.Concerning the VRLA battery, undercharge is overcharged more serious to the hazard ratio of battery, is even more important so improve the charge acceptance of VRLA battery.In the cathode lead plaster prescription, add the swelling agent and the conductivity additive of high stability, improved charge acceptance.
(3) improve over-discharge property.Reduce the proportion of sulfuric acid electrolyte, and added special electric solution additive, can reduce corrosion, reduce the generation of electric liquid layering, improved the charge acceptance and the over-discharge property of battery pole plate.
(4) adopt special safety valve.For the highlands,, adjusted the safety valve pressure value especially because atmospheric pressure is lower.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises solar cell 1, controller 2, batteries 3, inverter 4, DC load 5, AC load 6; Solar cell 1 is connected with controller 2, and controller 2 is connected with batteries 3, and inverter 4 is connected with controller 2, and DC load 5 is connected in controller 2 and is connected with inverter 4, and AC load 6 is connected with inverter 4.
This embodiment has following beneficial effect:
(1) raising recycles the life-span.For prolonging the life-span that recycles of VRLA battery, grid alloy should be good in the corrosion layer conductivity of grid and reactive species interface formation, and grid should have creep-resistant property.Battery design adopts tight assembling, and suitably improves assembling pressure.
(2) improve the battery charge ability to accept.Concerning the VRLA battery, undercharge is overcharged more serious to the hazard ratio of battery, is even more important so improve the charge acceptance of VRLA battery.In the cathode lead plaster prescription, add the swelling agent and the conductivity additive of high stability, improved charge acceptance.
(3) improve over-discharge property.Reduce the proportion of sulfuric acid electrolyte, and added special electric solution additive, can reduce corrosion, reduce the generation of electric liquid layering, improved the charge acceptance and the over-discharge property of battery pole plate.
(4) adopt special safety valve.For the highlands,, adjusted the safety valve pressure value especially because atmospheric pressure is lower.
