Technical field
Photovoltaic plant technology field is the utility model is related to, in particular it relates to Overwater-floating floating photovoltaic plant inversion boosting Stage apparatus.
Background technology
Possess a large amount of Unutilized Energies in provinces such as China western part Qinghai, Xinjiang, Gansu and illumination is sufficient, past several years Power station is mainly built in these areas.But these areas are not load centers, with the great development of photovoltaic in recent years, have been produced Serious abandons optical phenomenon.And at North China, these power load centers of Central China, limited by land status, photovoltaic plant is Develop toward mountain region, soil is also more and more nervous.
Overwater-floating floating photovoltaic plant turns into the problem of Jin Liangnian governments at all levels concern, photovoltaic plant waterborne in this context It is that photovoltaic module is swum in into the water surface using base station waterborne to be generated electricity.Feature is to be not take up land resource, and water body is to photovoltaic Component has cooling effect, can suppress the rising of assembly surface temperature, so as to obtain higher generated energy.
By taking Anhui Province as an example, although two Hua Areas area solar energy resources concentrates photovoltaic generation item compared with horn of plenty due to developing The reasons such as mesh floor space is big, Unutilized Energy is few, power network access conditions difference, constrain the development of photovoltaic industry.Through it is long when Between research, main direction of the Bureau of Energy of Anhui Province using the mining subsidence area water surface as photovoltaic generation base.
The photovoltaic plant waterborne developed at present, only develop floating body and arrangement cable and the placement remittance of support photovoltaic module Flow the floating body of case.And photovoltaic DC-to-AC converter and photovoltaic step-up transformer are not considered also to be placed on the water surface, traditional approach is littoral Place so that header box, for large-scale floating power barge (more than 10MW), takes up an area on hundreds of to the cable length increase between inverter Thousand mu, length of cable can reach several kilometers, and this can cause investment increase, generated energy loss increase, the increase of power station failure risk, fortune Tie up difficult management.
Through retrieval:
Application No. 201620117589.8, entitled " a kind of floatation type inversion boosting TRT ", discloses one kind Floatation type inversion boosting TRT, it includes the floating on water surface of inversion box, transformer, inner hollow or internal filling-foam thing Platform.Inversion box, transformer are arranged on floating on water surface platform;The periphery of floating on water surface platform is provided with some gravitational equilibriums Case.The utility model can break through the position limitation of traditional inversion boosting TRT, and inverter and case are become into (transformer) floating So can be that the arrangement of square formation is accomplished to optimize, simultaneously because inversion boosting TRT can be adopted among photovoltaic arrays It is well many compared to the reinforced concrete foundation that limitation pours with factorial praluction, its quality, and it is very convenient to construct.
Application No. 201520782137.7, entitled " Overwater-floating floating inversion boosting device and photovoltaic plant waterborne ", Including floating platform, box inverter, box type transformer and fixing device;Floating platform has hollow cavity and enters the maintenance of cavity Passage, floating platform are provided with direct current cables entrance and the outlet of high-voltage alternating cable;Box inverter is fixed on the deck of floating platform, set It is equipped with direct current connecting groove and exchanges connecting groove;Box type transformer is fixed on the deck of floating platform, is provided with low pressure connecting groove and height Crimp wire casing;The exchange connecting groove of box inverter and the low pressure connecting groove of box type transformer are electrically connected by connector, and Connector is located in the cavity of floating platform;Fixing device is used for the position for fixing floating platform.Overwater-floating floating disclosed in the utility model Inversion boosting device, the length of the cable between photovoltaic array is shortened, so as to reduce the electric energy loss of system.
Application No. 201620458433.6, entitled " a kind of mounting platform of floating on water surface photovoltaic plant equipment ", bag Raft and anchoring piece are included, the raft includes armored concrete casing and is filled in reinforced concrete box body Light filling layer, the anchoring piece include anchor block and the anchor line being connected between the armored concrete casing and anchor block, institute The surrounding for stating armored concrete casing is provided with the anchor point of reserved steel bar formation, and the anchor line is connected on anchor point, in institute State the built-in fitting being provided with armored concrete casing for installing equipment.Mounting platform of the present utility model, ensureing to carry On the premise of power, there is lightweight and floatable feature, be fixed on by the way that photovoltaic plant equipment will be made on mounting platform, photovoltaic electric Station equipment is arranged close to photovoltaic module, greatly reduces the use of cable, so as to reduce cost of investment, reduce generated energy loss and increasing Add benefit.As a kind of safe and stable, reliable floating on water surface photovoltaic plant Equipment Foundations.
Because inverter, step-up transformer dead weight are excessive, several tons to tens tons, the stable peace of these equipment Complete being placed on is extremely difficult on the water surface, and the single floating body (1~2 meter of length, width and height) that support photovoltaic panel can not have been used similar is carried out Support is fixed, because buoyancy is far not by far up to the mark.In addition, the structure of simple steelframe+buoyancy tank can not be used, on the water surface Long-term fluctuation in real time in, steelframe can produce fatigue damage, buoyancy tank can stress and it is damaged, cause whole system to destroy.On State that the resistance to overturning of first technical scheme is inadequate, and the height of platform can not be adjusted.
Therefore need to design and develop a can support the electrical equipments such as super large weight inversion boosting device and can on the water surface Platform run steadily in the long term, reliable in quality.And when the water surface elevation in dry season wet season changes, it is necessary to platform Can be adaptive, i.e., platform follows water surface elevation to change and oscilaltion in relatively-stationary region.
