Description
Technical field
The utility model relates to photovoltaic electric power field, is in particular a kind of compress air system of photovoltaic electric power.
Background technology
Photovoltaic generation is the target of the life that the mankind long for very much, photovoltaic plant: 1, photovoltaic plant continued power, 2, photovoltaic plant powers in a large number, 3, photovoltaic plant power supply at a low price.Only have and realize such photovoltaic plant, photovoltaic electric power could replace the main stream that existing fossil energy electric power becomes society.
Photovoltaic generation theory obtains the consistent approval of government and society, government gives to support energetically and help on policy, society has dropped into the construction that huge capital carries out photovoltaic products production and photovoltaic plant for this reason, but the effect of photovoltaic generation is very undesirable: due to power quality problem after a large amount of ground light overhead utilities builds up, cannot to power online, to abandon optical phenomenon very serious; The area that when solar radiation is built in a large amount of distributed photovoltaic power station in, number is short, as 3,4 classes areas: sunshine time is short, and photovoltaic cell resource utilization is low.Cause the basic reason of this phenomenon to be government, the social feature do not had according to solar energy resources, set up systems organization and development that photovoltaic generation industry is carried out in photovoltaic thinking.
The feature of solar energy resources: 1, energy density is low, 2, illumination is intermittent, 3, region sunshine time difference.Solar energy resources utilizes must according to this feature, set up photovoltaic thinking: the feature that energy density is low determines that photovoltaic plant needs a large amount of lands used and a large amount of cell panels, require that wide, the easy acquisition in the on-site soil of photovoltaic plant, land used cost are low, require that cell panel cost of goods manufactured is low; The intermittent feature of illumination determines that photovoltaic electric power cannot directly dynamically use, the energy pond and secondary electricity generation system that store solar energy must be set up, although compressed-air actuated energy density is very low, but match with the low density feature of solar energy, although low-density compressed air reservoir volume is very large, but the installation site of photovoltaic cell can, to hold, therefore be desirable solar energy storage system completely; Region sunshine time difference directly affects the efficiency of photovoltaic cell, but the area that sunshine time is long, sparsely populated, away from large electricity consumer, therefore must solve the digestive problems on the spot of photovoltaic generation electric power, the capacity scale of photovoltaic plant must be improved, reach economy and externally transmit electric power.
Be 201310639116.5 according to the photovoltaic thinking patent No., propose the scheme in the independent photovoltaic power station of self-loopa dilatation, but due to the intermittent feature of photovoltaic electric power, existing compressed air technique cannot be collected all intermittent photovoltaic electric powers and be used for compressed air, causes photovoltaic utilization rate of electrical low.Therefore, the whole intermittent photovoltaic electric power that the solution photovoltaic cell that the utility model proposes sends is used for compressed-air actuated technical scheme, is of great importance to the utilance improving photovoltaic electric power.
Utility model content
The purpose of this utility model is: the compress air system providing a kind of photovoltaic electric power, and all intermittent photovoltaic electric power that photovoltaic cell can be made to send is used for compressed air, improves the utilance of photovoltaic electric power.
The utility model is achieved through the following technical solutions: a kind of compress air system of photovoltaic electric power, is characterized in that: comprise one group of photovoltaic cell plate module, at least two air compressing devices, air accumulator and electric-control systems; Described at least two air compressing devices are parallel-connected on air accumulator, and photovoltaic cell plate module exports electrical network and connects at least two air compressing devices; Electric-control system connects electrical network and air compressing device respectively; The electrical quantity (such as electric current, voltage etc.) that electric-control system exports electrical network according to photovoltaic battery module changes the electric motor starting and the shutdown that control each air compressing device.
In order to better implement this programme, also provide following prioritization scheme:
Further, the power of motor of described every platform air compressing device is set to vary in size.
Further, to be set to size identical for the power of motor of described every platform air compressing device.
The beneficial effects of the utility model are:
Because the air compressor motor watt level of described multiple stage compression set is different, when daylight is very weak, as sooner or later, control electric motor starting in the compression set that in multiple stage compression set, power is minimum by electric-control system according to the actual electrical parameters of photovoltaic battery module output electrical network and realize compressed air; When daylight is very strong, as noon, export the actual electrical parameters motor controlled in multiple stage compression set of electrical network by electric-control system according to photovoltaic battery module all to start and realize compressed air, as long as the power of motor of a compression set in multiple stage compression set is enough little, all intermittent photovoltaic electric power that photovoltaic cell just can be made to send is used for compressed air.
