Description
Technical field
The utility model relates to a kind of electricity generation system, particularly a kind of Intelligent dual-mode photovoltaic generating system.
Background technology
Present photovoltaic generation is divided into 2 types: a kind of is parallel network power generation, and namely photovoltaic generates electricity and can directly be connected to the grid by inverter; Another kind is photovoltaic off-grid generating, and namely photovoltaic generates electricity to deposit in and passes through inverter behind the storage battery or directly for load, off-grid system can not access electrical network.
But all there is certain problem in these two kinds of photovoltaic generation types at present: for parallel network power generation, inverter also must turn-off simultaneously in electrical breakdown, otherwise can cause human casualty accident, and solar energy resources is wasted like this; Generate electricity for photovoltaic off-grid, when load is used seldom or is obsolete, after being full of storage battery, solar power generation then can stop generating, solar energy resources then is wasted and can't utilizes, and sometimes also has solar power generation and the possibly situation that can't satisfy its actual demand of storage battery electric energy in the very large situation of bearing power.
Along with the attention of environmental protection and energy saving and everybody to demand cheap, green energy resource, solar power generation may enter into more user and family, also just intelligence is incorporated into the power networks, has higher requirement from the net photovoltaic generating system, with the maximized utilization of solar energy resources.
The utility model content
Utility model purpose: for the problems referred to above, the purpose of this utility model provide a kind of automatic conversion be incorporated into the power networks, from the intelligence system of net photovoltaic generation, solve when generating electricity by way of merging two or more grid systems user after the outage and can not use the photovoltaic solar electric energy and can not be connected to the grid and cause the problem of solar energy resources waste from net photovoltaic generating system unnecessary solar power generation resource when the load need for electricity is low.
Technical scheme: a kind of Intelligent dual-mode photovoltaic generating system, comprise solar power generation assembly, inverter, storage battery, load, electrical network, inverse switch, power network switch, also comprise controller, described inverter and described storage battery parallel connection are connected into described controller, described controller is connected with described solar power generation assembly, described load is connected into described inverter by described inverse switch, and described electrical network is connected into described load by described power network switch.
Described controller is preferential to be communicated with described solar power generation assembly to described charge in batteries.
Principle of the present utility model is: controller detects accumulator electric-quantity, controller control solar power generation assembly generating priority of supply charge in batteries in the situation of storage battery quantity not sufficient, and the unnecessary electric weight offered load of solar power generation assembly generating is used; The controller control solar power generation assembly direct offered load of generating electricity is used in the situation of accumulator electric-quantity abundance, if the load power consumption less than solar power generation assembly energy output, then unnecessary electric weight is directly incorporated the upper level electrical network into; After the darkness or solar energy resources when not enough; controller sends instruction and cuts off mains supply; preferentially discharge electric energy to inverter by storage battery; direct current is converted to alternating current for load; when the storage battery electric energy satisfies the load electricity consumption; controller sends instruction access mains supply, and electrical network carries out charge protection to storage battery simultaneously, and it is rear stand-by that storage battery is full of electricity.
Beneficial effect: compared with prior art, the utility model has the advantages that by controller automatically conversion be incorporated into the power networks, from the net photovoltaic generation, maximum using solar energy resources and solar facilities, in the situation of electrical breakdown by storage battery to load supplying, the unnecessary electric energy that satisfies after load is used at solar power generation in the good situation of electrical network is connected to the grid, solar energy resources is fully utilized, photovoltaic apparatus is fully utilized.Reach according to user's actual load in 50% situation of Design cooling load, but 1KW photo-voltaic power generation station saves energy 500KWh/.
