The utility model relates to a kind of energy-storage system controller, relates in particular to a kind of novel household energy-storage system controller.
Background technology
In recent years, along with the sustained and rapid development of national economy, people are growing to the demand of electric power, and at present conventional electric power resource is released from sufferings in short supplyly, and solar energy relies on it pollution-free, renewable, inexhaustible etc., and feature has obtained paying close attention to widely and applying.Photovoltaic DC-to-AC converter, as the fresh combatants of regenerative resource, all gives the installation that photovoltaic combining inverter is encouraged in certain subsidy both at home and abroad.But the inherent shortcomings such as photovoltaic generation has unsteadiness, discontinuity, large-scale photovoltaic access makes a large amount of power electronics transducers introduce electric power system, and electric power system is caused to serious power quality problem.Therefore, reasonably control grid-connected electric energy, to improving the power quality problem of electric power system, ensure that the safe operation tool of electric power system is of great significance.
Chinese utility model patent specification CN 202617043 U are a kind of like this family expenses photovoltaic power supply system openly, comprises storage battery, controller, solar photovoltaic cell panel, load.Civil power is connected with controller, and controller is connected with storage battery, solar photovoltaic cell panel respectively, and controller connects load.Described family expenses photovoltaic power supply system, powers by civil power, solar photovoltaic cell panel, storage battery three sources.The photovoltaic electric power of solar photovoltaic cell panel output is similar to low pressure, the direct current of common batteries, and it is 12V that voltage is set, open voltage 17-18V.Load is carried out work by the photovoltaic electric power providing.Meanwhile, the photovoltaic electric power that battery stores is unnecessary, battery capacity is 12V/12-20AH.And connection utility grid, supplements and distribution.Controller can auto switching electric source.This utility model adopts the power supply of DC low-voltage electricity, has changed traditional ac power supply method.Safe and reliable, simple and convenient, economy is high.But this electric power system can not realize user and generate power for their own use to greatest extent, can not realize user benefit and maximize.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of novel household energy-storage system controller, generate power for their own use to greatest extent utilizing this novel household energy-storage system controller to realize user, improved the operating efficiency of energy-storage system, realize user benefit maximization, reduced user power utilization amount, reduced user power utilization cost, reduced as much as possible feedback net power, slow down the impact to electrical network, utilize to greatest extent clean energy resource, avoided environmental pollution.
In order to solve the problems of the technologies described above, novel household energy-storage system controller of the present utility model comprises photovoltaic, bidirectional energy-storage inverter, energy-storage battery, controller, load, two-way ammeter, electrical network, bidirectional energy-storage inverter is connected with photovoltaic, energy-storage battery, two-way ammeter respectively, two-way ammeter is connected with electrical network, bidirectional energy-storage inverter is connected with load with two-way ammeter, and controller is connected with bidirectional energy-storage inverter, two-way ammeter, energy-storage battery respectively by connection.
Described novel household energy-storage system controller also comprises server, and server is connected with controller by connection.
Described novel household energy-storage system controller also comprises that LCD is connected with controller by connection.
Described energy-storage battery comprises the communication interface with the applicable CAN agreement of controller communication.
Described two-way ammeter comprises the communication interface with the applicable MODBUS agreement of controller communication.
Adopt such family expenses energy storage controller, can priority of supply when have solar energy daytime domestic loads, charge the battery, if there is the residue will be upper to electric national grid simultaneously; Used the solar energy being stored in daytime in battery night, if deficiency is again from electrical network power taking.Simultaneously due to this controller, realize user to greatest extent and generated power for their own use, greatly reduced user's feed dynamics, slowed down the grid-connected impact to electrical network end.According to online subsidy policy, this controller system can bring certain economic benefit to user simultaneously.Owing to also comprising server and LCD, user can surf the Net or check oneself electricity consumption situation at home like this.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the schematic diagram of the utility model novel household energy-storage system controller.
Embodiment
The energy-storage system of novel household shown in Fig. 1 controller comprises photovoltaic, bidirectional energy-storage inverter, energy-storage battery, controller, load, two-way ammeter, electrical network, server, LCD, bidirectional energy-storage inverter respectively with photovoltaic, energy-storage battery, two-way ammeter connects, two-way ammeter is connected with electrical network, bidirectional energy-storage inverter is connected with load with two-way ammeter, controller by connection respectively with bidirectional energy-storage inverter, two-way ammeter, energy-storage battery, server, LCD connects, energy-storage battery comprises the communication interface with the applicable CAN agreement of controller communication, two-way ammeter comprises the communication interface with the applicable MODBUS agreement of controller communication, bidirectional energy-storage inverter, LCD, server all comprise can with the common interfaces of controller Direct Communication.
When daytime, photovoltaic was normal, controller preferentially by photovoltaic electric energy for load, when bearing power is greater than photovoltaic power output, if energy-storage battery has electric energy, will preferentially use the electric energy of energy-storage battery, if still not enough, will be from electrical network power taking; When bearing power is less than photovoltaic power output, if energy-storage battery less than, will be preferentially for energy-storage battery charging, if the residue of still having, by feed to electrical network.When the abnormal or photovoltaic power output of photovoltaic on daytime is very little, controller will preferentially be controlled energy-storage battery bearing power will be provided, if still not enough, will be from electrical network power taking.When night, the preferential energy-storage battery of controller provides bearing power, if still not enough, will be from electrical network power taking.When domestic loads changes, controller can regulate rapidly energy-storage battery power output automatically, to meet the demand of domestic loads.When long-term, without photovoltaic, while causing battery undervoltage, controller will make system carry out grid charging pattern, by electrical network, to grid charging, avoid long-term under-voltage condition, affect battery life.
Certainly; this energy-storage system controller principle can also be applied to other aspects; as wind power generation energy accumulation system, small hydropower station energy-storage system; they control method and principle similar; do not departing under the prerequisite of the utility model principle, within these change and all drop on protection range of the present utility model.
