Description
Technical field
The utility model relates to a kind of solar energy photovoltaic generator, particularly composite type three-phase solar photovoltaic grid-connection power station.
Background technology
As everyone knows, the large-scale application of regenerative resource will be the important symbol of 21 century human social development.Realize this goal, at first must finish regenerative resource by the additional energy to the alternative energy source transition, even regenerative resource is developed to the routine that the electricity area the is arranged direction of generating electricity by way of merging two or more grid systems by the independently-powered pattern of outlying areas without electricity, this will improve the utilance of regenerative resource greatly.And, become the heat subject that countries in the world fall over each other to study at present just day by day how as soon as possible with the development of solar photovoltaic grid-connection generation technology and make it to grow up.
The utility model content
The purpose of this utility model is to provide a kind of composite type three-phase solar photovoltaic grid-connection power station, and the technology maturity height is practical, simple and reasonable for structure, has wide application development prospect.
The purpose of this utility model is achieved in that a kind of composite type three-phase solar photovoltaic grid-connection power station, this power station comprises at least three separate photovoltaic module arrays and at least three single-phase photovoltaic DC-to-AC converters together parallel with one another together parallel with one another, be cascaded by the CAN bus successively between these three photovoltaic DC-to-AC converters, one end of CAN bus is connecting cluster control unit, and cluster control unit is connecting the control computer by the RS232 communication line; The output of three photovoltaic module arrays is connecting this three photovoltaic DC-to-AC converters respectively, and the output of photovoltaic DC-to-AC converter links to each other with electrical network by electric quantity metering device.
A plurality of inverter parallels in the utility model power station, when morning, sunlight changed from weak to strong, cluster control unit chooses an inverter to put into operation at random earlier, when first inverter drops into an inverter again near full load, simultaneously cluster control unit by instruction with the inverter load sharing.Withdraw from the work of generating electricity by way of merging two or more grid systems when controlling each inverter by cluster control unit at sunset by platform.The input of inverter and withdraw from fully and distribute according to the gross power of photovoltaic array by cluster control unit, loss in the time of can reducing the low load of inverter so to greatest extent, " be bankers by turns " owing to each inverter simultaneously, do not put into operation when not required, thereby prolonged useful life of each inverter greatly.
In addition, when certain combining inverter breaks down in the network, itself and alternating current-direct current bus are disconnected, so also can realize the redundancy running of whole system, thereby increase the operational reliability of system greatly.
Cluster control unit obtains all operational factors, malfunction and the generating parameter of each inverter by the CAN bus, is uploaded to the control computer by the RS232 bus, is convenient to centralized management, improves the efficiency of management and reliability, reduces management difficulty, and is easy and simple to handle.
The utility model power station not only no-load loss is low, has improved solar energy utilization ratio, and the utility model power station technology maturity height, practical, simple and reasonable for structure, application development prospect is wide, can greatly alleviate the shortage of electric power situation of China remote districts.
