The utility model discloses a simple structure, low cost can effectively improve power system operation's stability, economic nature and electric energy quality.

Description

The direct insertion energy storage device of photovoltaic
Technical field
The utility model relates to a kind of energy storage device, specifically, relate to the direct insertion energy storage device of a kind of photovoltaic.
Background technology
At present, along with socioeconomic development, the new forms of energy development such as photovoltaic generation rapidly.Along with grid-connected photovoltaic capacity increases gradually, reduce the electric power storage waste of photovoltaic generation in course of conveying by certain technological means and there is important economic implications.Meanwhile, the update of photovoltaic technology, the battery price as energy-accumulating medium significantly reduces, and electric power network technique also improves constantly, and makes the commercial operations of photovoltaic generating system battery energy storage become possibility.But, still exist in the photovoltaic generating system battery energy storage system of current China and how to weaken the technical barrier of Large Copacity polymerization to electric network influencing.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides the direct insertion energy storage device of a kind of structure photovoltaic simple, easy to use, with low cost.
To achieve these goals, the technical scheme that the utility model adopts is: the direct insertion energy storage device of a kind of photovoltaic, comprise solar panel, mixed type inverter, batteries, A.C. distribution box and power load, described solar panel is connected to described batteries and described A.C. distribution box by described mixed type inverter, described mixed type inverter is also connected in AC network with detachably direct insertion, described mixed type inverter is the DC conversion described batteries exported is alternating current, and control the charge and discharge process of described batteries.
Based on above-mentioned, described mixed type inverter is provided with multiple charge and discharge control channel.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model by being connected with described mixed type power governor in described batteries, with on solar panel with batteries, be separately equipped with power governor compare, total cost can be made to reduce one one-tenth, and energy conversion loss is few.Further, this utility model structure is simple, with low cost, effectively can improve the stability of power system operation, economy and the quality of power supply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
The present embodiment provides a kind of photovoltaic direct insertion energy storage device, specifically comprises solar panel 1, mixed type inverter 6, batteries 3, A.C. distribution box 4, uses electric loading 5 and direct insertion plug 2; Described solar panel 1 is connected to described batteries 3 by described mixed type inverter 6, described batteries 3 is charged, described mixed type inverter 6 is also connected in AC network by detachable direct insertion plug 2, is that direct current charges to described batteries 3 and controls the charge and discharge process of described batteries by the AC conversion in AC network.
Described electric loading 5 is connected on described mixed type inverter 6 by described A.C. distribution box 4, and the direct current be stored in described batteries 3 is powered to described power load 5 by described A.C. distribution box 4 after described mixed type inverter is converted to alternating current.
Described mixed type inverter 6 is provided with multiple charge and discharge passage, as expense mode of priority passage, priority for environmental protection mode passageway etc.
The direct insertion energy storage device of the photovoltaic that the present embodiment provides in routine duties, according to object, can be selected in multiple-working mode.Such as, under expense mode of priority, system can use cheap night electricity charging, uses the electric energy of storage by day, with power cost saving.And towards under self-centered priority for environmental protection pattern, the dump power of photovoltaic generation will be stored in storage battery and be used for daily life, to reduce from Utilities Electric Co.'s power purchase.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
