Description
Technical field
The utility model is related to a kind of accumulator cell charging and discharging control device, it is intended to so that obtained from grid-connected power generation system
Electric power can be exported stably to load, belong to technical field of new energy power generation.
Background technology
The non-renewable energy resources such as oil, coal are increasingly reduced, and the mankind continue to increase to the demand of the energy, new energy
Exploitation are the effective ways for solving this contradiction.
The utilization of new energy is again the most familiar with photovoltaic generation, wind-power electricity generation.Generation of electricity by new energy can reduce one
Divide the demand of fossil energy, but due to sunshine, the fluctuation of wind-force, the generating output of new energy can not keep stable.On flourishing ground
Area, huge power network perhaps can smooth these fluctuations, but in island or remote districts, such fluctuation will often influence to use
The normal operation of electric equipment, is not only easily damaged equipment, and the experience of influence user, trust of the reduction people to new energy.
Battery is often used as in grid-connected power generation system and met an urgent need or standby, typically as follows by the way of：If new
Energy generated energy is more than need for electricity, is just stored by battery；If generation of electricity by new energy amount is less than need for electricity, just use
Battery is supplemented.
A part of power fluctuation can be alleviated really in this way, but there is problems with：
1st, the moment is needed to track generation of electricity by new energy data, it is higher to control accuracy requirement.
2nd, batteries punching is put frequently, influences the service life of batteries.
The content of the invention
The purpose of this utility model is to provide a kind of accumulator control device suitable for grid-connected power generation system.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of suitable for grid-connected power generation system
Accumulator control device, including charging bus and bus, the electric energy that generation of electricity by new energy device is sent converges into charging bus, uses
Electric equipment is from bus power taking, it is characterised in that plurality of groups of storage batteries group is provided between charging bus and bus, per group storage battery group
One end by charge switch with charging bus be connected, the other end is connected by discharge switch with bus, and institute is controlled by controller
There are disconnection and the closure of charge switch and discharge switch.
The beneficial effects of the utility model are mainly as follows：
1st, the utilization ratio of new energy is improved.When avoiding generation of electricity by new energy peak, need for electricity is not but high and cause it is new
Using energy source is not enough；
2nd, the stability and reliability of new energy are improved.Avoid because sunshine, wind-force etc. change caused by power fluctuation to
The normal operation of electric equipment is impacted；
3rd, the popularization of new energy is promoted.
Brief description of the drawings
The schematic device that Fig. 1 provides for the utility model；
Fig. 2 is control logic block diagram.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in figure 1, a kind of accumulator control device suitable for grid-connected power generation system that the utility model is provided, bag
Include charging bus 2 and bus 6, the electric energy that generation of electricity by new energy device 1 is sent converges into charging bus 2, electrical equipment 8 is from bus 6
Power taking, is provided with plurality of groups of storage batteries group 4 between charging bus 2 and bus 6, and one end per group storage battery group 4 passes through charge switch 3
It is connected with charging bus 2, the other end is connected by discharge switch 5 with bus 6, is controlled all charge switch 3 by controller 7 and is put
The disconnection of electric switch 5 and closure.
With reference to Fig. 2, during utility model works, the charge switch 3 and discharge switch 5 at the same two ends of batteries 4 are different
When close.After controller 7 monitors that some batteries 4 meets discharging condition or be fully charged, its charge switch 3 disconnects.Store
Battery pack 4 can be with single or several electric discharges simultaneously.If the batteries 4 of present discharge meet discharging condition, continue to discharge.
If having in the batteries 4 of present discharge and being unsatisfactory for discharging condition, closure meets putting for the batteries 4 of discharging condition
Electric switch 5, is then turned off being unsatisfactory for the discharge switch 5 of the batteries 4 of discharging condition, subsequently closes 3 pairs of its charge switch
It charges.
Using this control device, batteries are regard as intermediate link of the generation of electricity by new energy to power supply for electrical equipment, it is to avoid
The fluctuation problem of generation of electricity by new energy.And due to need to only monitor the state of batteries, simple and stable is controlled, meanwhile, to storing
The regular charge and discharge of battery pack, is conducive to the service life of battery to a certain extent.
