Abstract
The utility model discloses a community solar energy micro electrical network two-stage scheduling system based on a super capacitor bank, which is characterized by comprising a solar cell array (1) in the community, wherein the solar cell array (1) is connected with a community energy storage commutation center (4) via a super capacitor tank temporary energy storage device (2), and the community energy storage commutation center (4) is respectively connected with a community minisize power station (3) and a commercial power access portion (5) via lines. The system has a bigger usage space, a longer cycling life and a higher energy usage efficiency, can provide a more stable power supply with higher quality, and overcomes defects of the current community micro electrical network systems. Little investment is needed for reconstructing the existing community micro electrical network. The system is in line with the requirement of environmental protection, and has better social benefit and practical value.
Description
Technical field
The utility model relates to a kind of little power network dispatching system, specifically relates to a kind of little electrical network two-level scheduler of sub-district solar energy system based on the super capacitor group.
Background technology
Along with the development of novel energy, solar power generation is by the increasing domestic consumer who is applied in the sub-district.The clean electric power of sending has satisfied the needs of sub-district family life, has also reduced traditional generation mode to environment damage.Micro-grid system in the residential quarter; Mainly be that to utilize solar panel be uncontrolled distributed power source; Other distributed power sources such as miniature gas turbine or diesel generating station; The civil power connecting system is all controlled exerts oneself, and therefore, the little dispatching of power netwoks in sub-district mainly is the scheduling to solar power system.All be arranged on roof, this phenomenon of metope to solar panel in the sub-district, and the influence of various indefinite weather, in order to guarantee stable output firm power, generally can set up concentrated chemical cell energy storage and inversion facility in the sub-district.The drawback of this structure is conspicuous; The output voltage of solar panel is not high, and it is very big to be transferred to the loss of center of housing estate current conversion station, the charging and discharging of accumulator limited service life; Because environmental change and repeated charge can increase cost, it is with high costs to set up current conversion station in each family.
Summary of the invention
The purpose of the utility model has overcome deficiency of the prior art exactly; A kind of little electrical network two-level scheduler of sub-district solar energy system based on the super capacitor group is provided; The various characteristics that fully adapts to family's use solar power generation in the sub-district; High efficiency, the energy scheduling of the little electrical network in long-life completion sub-district.
The new technical scheme that adopts of this practicality is following:
A kind of little electrical network two-level scheduler of sub-district solar energy system based on the super capacitor group; It is characterized in that it includes the solar cell group pattern in the sub-district; The solar cell group pattern links to each other with energy storage change of current center, sub-district through the temporary transient energy storage device of super capacitor group, and energy storage change of current center, sub-district is also inserted part through circuit with micro generation station, slight district and civil power respectively and linked to each other.
The beneficial effect of the utility model is:
Have bigger usage space, cycle life is longer, and the service efficiency of energy is higher.High-quality stable power more can be provided, overcome the deficiency of existing sub-district micro-grid system.Fund to the little electrical network in the sub-district of having built up only need drop into seldom just can be accomplished transformation.Meet requirements of green environmental protection, have better social benefit and practical value.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1; The utility model comprises the solar cell group pattern 1 in the sub-district; Solar cell group pattern 1 links to each other with energy storage change of current center, sub-district 4 through the temporary transient energy storage device 2 of super capacitor group, and energy storage change of current center, sub-district 4 is also inserted part 5 through circuit with micro generation station 3, slight district and civil power respectively and linked to each other.
The electric energy that solar cell group pattern 1 in the sub-district is produced is delivered to the temporary transient energy storage device 2 of super capacitor group earlier.The current capacity of exposure intensity, capacitance group according to current weather situation, each cell panel; Instruction is sent to the temporary transient energy storage device 2 of super capacitor group in energy storage change of current center, sub-district 4, and regulating mode of operation automatically is that energy storage still transmits stable electric energy to energy storage change of current center, sub-district 4.The temporary transient energy storage device 2 of super capacitor group can be eliminated other variation of day destiny minute level, also can adapt to each solar panel over time, the different and variation of exerting oneself that produces of irradiating angle.Can repeated charge to reduce the number of times that discharges and recharges of the 4 pairs of large-scale batteries in energy storage change of current center, sub-district, accomplish the first order scheduling of little electrical network.It is the energy scheduling of unit that energy storage change of current center, sub-district 4 can be responsible for the day; According to load and generator unit situation; Control the temporary transient energy storage device of each super capacitor group and exert oneself, part 5 is inserted with civil power in dispatching cell micro generation station 3, and the expending equilibrium of exerting oneself of accomplishing little electrical network is stable; Guarantee to accomplish the task of life power supply, thereby accomplish the second level scheduling of little electrical network in night, peak of power consumption and overcast and rainy ability.
The undeclared part that relates in the utility model is identical with prior art.
