Abstract
The utility model discloses a photovoltaic power station two-megawatt inverting boosting/integrated unit system. The photovoltaic power station two-megawatt inverting/boosting integrated unit system includes four 500-kilowatt photovoltaic power generation arrays, two three-winding box-type transformer substations and an inverting/boosting integrated unit, wherein the four 500-kilowatt photovoltaic power generation arrays are oppositely arranged, and the inverting/boosting integrated unit includes an inverter room located at the center of the diagonal lines of the four 500-kilowatt photovoltaic power generation arrays; four 500-kilowatt inverters and four direct-current cabinets are arranged inside the inverter room; and the output ends of every two inverters are connected with two low-voltage windings of one three-winding box-type transformer substation. According to the photovoltaic power station two-megawatt inverting boosting/integrated unit system of the utility model, the inverter room is arranged at the center of the four photovoltaic power generation arrays; and the two three-winding box-type transformer substations are adopted; and therefore, high integration of inverting and on-site boosting can be realized, as a result, a layout space can be saved, and the block of the photovoltaic arrays caused by the inverter room can be decreased, and operational maintenance can be facilitated, and the number of equipment and materials such as computer monitoring sub stations, power cables and optical cables can be decreased.
Description
Technical field
The utility model relates to the large-sized photovoltaic power field, relates to specifically photovoltaic plant two megawatt inversion boosting integrated unit systems.
Technical background
Investment, the place that the inversion boosting unit setting of large-scale grid-connected photovoltaic power station is related to power station takies, equipment operating cost, being in the large-sized photovoltaic Power Plant Design, to need the key problem of considering, is also one of problem of all paying much attention to of domestic and international researcher and project planner.
The inversion boosting unit that generally adopt in current large-sized photovoltaic power station is a megawatt to the maximum, and namely every 2 500 kilowatts of photovoltaic electricity generating arrays share inversion boosting unit.Because the inversion boosting cell capability is little, can make the inversion boosting element number increase, bring to tie up and arrange that place, computer supervisory control system substation equipment are many, the unfavorable factors such as expense and operating cost height are built in room.How in conjunction with the rationally distributed selection large capacity inversion boosting of the 2 megawatt unit of photovoltaic plant subarray, reduce the quantity of photovoltaic plant inversion boosting unit, make it to reduce investment outlay, reduce occupation of land, alleviate equipment operating cost, have not yet to see the report of all relevant this respects.
Summary of the invention
The utility model purpose is to provide a kind of photovoltaic plant two megawatt inversion boosting integrated unit systems.
For achieving the above object, the utility model is taked following technical proposals:
Described photovoltaic plant two megawatt inversion boosting integrated unit systems of the present utility model, comprise four 500 kilowatts of photovoltaic electricity generating arrays, two three winding box-type substations, inversion boosting integrated unit, and described four photovoltaic electricity generating arrays are symmetrical arranged; Described inversion boosting integrated unit comprises: the inverter chamber that is arranged on described four 500 kilowatts photovoltaic electricity generating array diagonal center positions, indoor four 500 kilowatts of inverters and the DC cabinet of being provided with of described inverter, described every two 500 kilowatts of inverter output ends connect with two low pressure windings of corresponding three winding box-type substations respectively.
The utility model advantage is described inverter chamber is arranged in the center of four photovoltaic electricity generating arrays, and select two three winding box-type substations, realize that inversion, the height boosted on the spot are integrated, with a current conventional megawatt inversion unit, compare, both save the layout place, reduced the inverter chamber to the blocking of photovoltaic array, facilitated operation maintenance, also reduced the quantity of computer monitoring substation and the equipment and materialss such as cable, optical cable, saved room and built expense.
