Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Fig. 1 is the structure composition schematic diagram of the utility model system.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection range of the present utility model.
As shown in Figure 1, energy storage feedback net system provided by the utility model unified implementation structure composition diagram, comprises three-phase mains electrical network L1, L2, L3, N, live wire L1, L2, L3 is connected to electric loading R1, load R2 and load R3.Solar panel 1 is connected with controller 2.Energy-storage battery 3 is connected with controller 2.Controller 2 inside is integrated with inversion module, control module, charging module and communication module.
Between live wire L1, L2, L3 and controller 2, be respectively arranged with arrangement for detecting s1, arrangement for detecting s2, arrangement for detecting s3 and switch u1, switch u2, switch u3.That is, arrangement for detecting s1 connects three phase network L1, and arrangement for detecting s2 connects three phase network L2, and arrangement for detecting s3 connects three phase network L3, and switch u1 connects three phase network L1, and switch u2 connects three phase network L2, and switch u3 connects three phase network L3.Wherein, the zero line N that arrangement for detecting and switch share is connected with the zero line N of three-phase mains.Load R1, R2, R3 one end connects live wire L1, L2, L3 of civil power respectively, and the other end is all connected with zero line N.The corresponding connection control device 2 of both positive and negative polarity of solar panel 1, the corresponding connection control device 2 of both positive and negative polarity of energy-storage battery 3, controller 2 communication interface connects computer 4.
Native system is started working, and the watt level learning each the road live wire in current three-phase mains and load R1, R2, the R3 on zero line detected by controller 2 by arrangement for detecting s1 or s2 or s3.
When solar panel 1 has electric power to produce, its electric energy power produced is P, and controller judges the relativity of P and load R1, R2, R3, selects a wherein road, and this way switch closed carries out feed to it.Its basis for estimation is as follows:
1), when the electric energy P that solar panel produces is less than the power of arbitrary load R1, R2, R3 consumption, controller closes default switch (default switch is set to u1) herein, carries out feed to load R3; This default switch can carry out arranging or changing according to the actual needs of user.
2) when the electric energy P, produced when solar panel is greater than the power of arbitrary load R1, R2, R3 consumption, controller closes the large load place line switching of power drain, feed is carried out to this road load, electric energy P is greater than the dump energy that this road load consumes, then charge to energy-storage battery 3 or upload to electrical network;
3), as the electric energy P of solar panel generation be less than the power consumed in load R1, R2, R3, when being greater than the power of other two loads consumptions, controller closes the switch higher than electric energy P Na mono-tunnel load, carries out feed to it;
4), when solar panel produce electric energy P be less than in load R1, R2, R3 any two consume power, when being greater than one of them, controller opens arbitrary higher than in two loads of electric energy P to inductive switch, feed is carried out to it.
When solar panel produce electric power meet load demand and have unnecessary or non-loaded, and the electricity of energy-storage battery does not reach the standard of setting, then controller is by its charge inside module, is generated electricity by solar panel and can be used for for the charging of energy-storage battery group; Reach the standard of setting in energy-storage battery charge value after, solar panel institute electric energy more than needed, through inversion module, imports electrical network into by the path opened.
Below by way of a specific embodiment, the utility model feedback network method is described further:
If arrangement for detecting only detects on a circuit electric current, as R1 work, power 1kw, then electric current 4.5A (line voltage is 220V), then u3 closes, by combining inverter operation principle, by the electric current that provides of electrical network reduce gradually from 4.5A, the electric current that solar panel provides increases gradually, and is finally all provided through inverter by cell panel.
If detect on two circuits and have electric current, R1 works, power 1kw, electric current 4.5A; R2 works, power 2kw, electric current 9A.Then u2 closes, and R1 is worked by mains supply, and R2 is by cell panel powered operation.
When the electric energy P that solar panel produces is greater than the power of arbitrary load R1, R2, R3 consumption, feed is carried out to high-current circuit.Dump energy, then charge to energy-storage battery or upload to electrical network.Meanwhile, energy-storage battery soc (StateofCharge) is less than certain value, as 90%, then charges to energy-storage battery.If be greater than 90%, then do not charge, upload electrical network.
If loaded work piece power exceedes the size of the electric energy that cell panel provides, then closed default switch u1 (but oneself setting), as R1, R2, R3 work, and power is 4kw, be greater than the power 3kw that cell panel provides, then cell panel provides 13.5A electric current, and electrical network provides 4.5A electric current.
Feedback net system provided by the utility model, by above technical scheme, as required, each is connected with one in three-phase mains, automatically can selects and be switched to the phase civil power needing feed.
Energy storage feedback net system provided by the utility model can be any the grid-connected feed in photovoltaic, wind energy or energy-storage battery.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
