Research On Electrical Design Of Civil Photovoltaic System In China

In recent years,distributed photovoltaic systems developed rapidly in ourcountry, distributed photovoltaic systems is civil building photovoltaicsystems.the outer surface of the building could become solar radiationreceiving surface,without taking up additional land,save valuable landresources;energy self-occupied,saving transmission and distribution equipmentand investment in grid,reducing the power consumption;summer as the peakperiod,coinciding with solar radiation and photovoltaic power generation atmost,can ease the power grid peak pressure from to peaking effect;does notproduce any emissions damage the ecological environment conducive to thepublic dissemination of green building concept.However, experience inelectrical design of civil photovoltaic systems are not enough,a seriousimpediment to the development of photovoltaic technology taking a stepforward,and research combining better with the actual situation of electricaldesign of civil photovoltaic systems is imminent in our country.In this paper,the classification and composition of civil photovoltaicsystems were studied,detailed analyzed of the advantages and disadvantages ofphotovoltaic cells,characteristic parameters and electrical characteristics ofphotovoltaic cells,classification and characteristic parameters of energystorage device and inverter,analyzed of the principles and content of civilphotovoltaic system electrical design,studied the design of photovoltaicsystems,proposed residential underground garage lighting photovoltaic systemelectrical design.In a building of a residential area as an example,the use ofcomputer-aided design software PVSyst,according to the actual conductedelectrical design and simulation of residential underground garage lightingphotovoltaic system,had been generating capacity of photovoltaic systems andthe relationship between photovoltaic array area and the underground garage area,and then analyzed grid-connected advantages and design content of civilphotovoltaic systems,studied the design of grid-connected.In grid-connectedlinks of a photovoltaic system as an example,conducted electricaldesign,simulation and benefit analysis.This paper studied electrical design of civil photovoltaic systems,aims togain experience and provide reference in the application of civil photovoltaicsystems,enable civil photovoltaic systems has been more widely used in China.
