Description

Independent photovoltaic generating system
Technical field
This utility model is related to technical field of photovoltaic power generation.
Background technology
Photovoltaic generation, refers to and adopts photovoltaic module, and solar energy is converted directly into into the electricity generation system of electric energy.It is a kind of new Type, have it is with broad prospects for development generating and comprehensive utilization of energy mode.
Photovoltaic generating system is divided into grid-connected photovoltaic power generation system and independent photovoltaic generating system.Grid-connected photovoltaic power generation system can National grid is accessed, it advocates and generates electricity nearby, grid-connected nearby, changes nearby, the principle for using nearby, can not only effectively improve The generated energy of same size photovoltaic plant, while also efficiently solving the problems, such as loss of the electric power in boosting and long-distance transport.Solely Vertical photovoltaic generating system is independently-powered, does not access national grid, and its generating does not rely on national grid, and dump energy can be stored in In accumulator so that photovoltaic generation is fully used.
Existing independent photovoltaic generating system when photovoltaic does not generate electricity using accumulator powering load, the electricity in accumulator Amount is limited, can support and use load time limited, is to load to use to make troubles.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, there is provided a kind of independent photovoltaic is sent out Electric system, simple structure is easy to use, can be continuously load supplying, it is ensured that load is normally used.
To solve above-mentioned technical problem, technical solution adopted in the utility model is:Including photovoltaic module, photovoltaic control Device, Intelligent Switching Device, load, accumulator battery and power set;Photovoltaic module is connected with photovoltaic controller, photovoltaic controller Outfan is connected with the input of Intelligent Switching Device, and load is connected to after Intelligent Switching Device;Accumulator battery is filled with intelligent conversion Put connected, power set are connected with the access interface on Intelligent Switching Device.
Preferably, being additionally provided with intelligent controlling device between Intelligent Switching Device and load.
Preferably, intelligent controlling device is intelligent power distribution cabinet.
It is using the beneficial effect produced by above-mentioned technical proposal:This utility model simple structure, easy to use, electric power storage Even if pond can also be continuously load supplying with the combination of electromotor in long-term rainy weather, it is ensured that load is normally used, intelligence The power supply of power distribution cabinet control load.

Fig. 1 is the structured flowchart of this utility model one embodiment.
In figure:1st, photovoltaic module;2nd, photovoltaic controller;3rd, Intelligent Switching Device;4th, intelligent controlling device;5th, load;6、 Accumulator battery;7th, power set.
Specific embodiment
This utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, for a kind of one embodiment of independent photovoltaic generating system of this utility model, including photovoltaic module 1, Photovoltaic controller 2, Intelligent Switching Device 3, load 5, accumulator battery 6 and power set 7;Photovoltaic module 1 and the phase of photovoltaic controller 2 Even, the outfan of photovoltaic controller 2 is connected with the input of Intelligent Switching Device 3, and load 5 is connected to after Intelligent Switching Device 3;Store Set of cells 6 is connected with Intelligent Switching Device 3, and power set 7 are connected with the access interface on Intelligent Switching Device 3.
Photovoltaic controller 2 controls photovoltaic size of current, and Intelligent Switching Device 3 can control the discharge and recharge of accumulator battery 6 again The conversion between accumulator battery 6 and power set 7 can be controlled.Simple structure, it is easy to use, when normally using, the institute of photovoltaic module 1 Generated energy is used by a part of electricity of Intelligent Switching Device 3 through photovoltaic controller 2 for load 5, and unnecessary electricity is stored into storage Set of cells 6, when rainy weather photovoltaic module 1 can not generate electricity, accumulator battery 6 starts to discharge and uses for load 5, while intelligence turns Changing device 3 is controlled to the depth of discharge of accumulator battery 6, and when battery discharging depth is reached the limit values, system carries out early warning, Intelligent Switching Device 3 starts the powering mode of power set 7, is generated electricity using power set 7 and is used for load 5, while power set 7 Institute's generated energy can also be charged by Intelligent Switching Device 3 to accumulator battery 6, and then reach the purpose that load 5 can be used persistently. The system is not affected by external conditions such as weather, and under can be suitably used for any environment, power set are connected with Intelligent Switching Device and carry For emergence power, use range is extensive.
Intelligent controlling device 4 is additionally provided between Intelligent Switching Device 3 and load 5, intelligent controlling device 4 can control load 5 power supplies.
Intelligent controlling device 4 is intelligent power distribution cabinet, and load can be divided into one-level load and earphone load by intelligent power distribution cabinet, When the depth of discharge of accumulator battery 6 reaches preset limit value, intelligent power distribution cabinet automatically cuts off the power supply of secondary loads, negative only for one-level Carry electricity consumption.
The system can be used on caravan, it is ensured that caravan also can normally using in-car load when sunlight is inadequate.Also may be used With on the buses scrapped, using waste and old buses shell, the tourist attractions etc. such as by the sea are disposed after buses are transformed Position, uses, energy-conserving and environment-protective for people's rest.
Using process:
The mode of operation of system is divided into following several grades:
(1)When system is normally run, one-level load and secondary loads can be used normally, and photovoltaic electric preferentially supplies car Interior load is used, and dump energy is charged in accumulator battery by Intelligent Switching Device;
(2)In rainy weather, when photovoltaic power generation quantity is not enough to for in-car load institute's subfam. Spiraeoideae, accumulator battery starts to put Electricity, supplements remaining deficiency electricity;
(3)When accumulator battery depth of discharge reaches preset limit value, intelligent power distribution cabinet automatically cuts off the power supply of secondary loads, Only for one-level load;
(4)When accumulator battery depth of discharge will be reached the limit values, system carries out early warning, and Intelligent Switching Device starts dynamic Power apparatus powering mode, is generated electricity for in-car load, while power set can also pass through Intelligent Switching Device using power set Charge a battery.
After above-mentioned technical proposal, simple structure is easy to use, even if the combination of accumulator and power set is long-term Rainy weather can also be continuously load supplying, it is ensured that load is normally used, the power supply of intelligent power distribution cabinet control load.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit this utility model Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
