Distributed Photovoltaic System Optimal Design For Rural

Photovoltaic system alleviate poverty is one of the effective models for targeted alleviate poverty and targeted overcome poverty.Photovoltaic system not only brings clean energy to users,but also increases the income and improves the living standard.In the 13 th Five Year Plan,photovoltaic system alleviate poverty work will blossom everywhere in China.Photovoltaic system alleviate poverty is the alleviate poverty of distributed photovoltaic system.The rural power-grid planning is not scientific and unreasonable,and also has the problem of poor power equipment,bad power quality and small transformer capacity and so on.So it is very important to distribute photovoltaic system optimal design for Rural.In this paper,taking Zhu ling Cun,Shangyou County,Ganzhou for example,focuses on the design of one-house one meter photovoltaic system and centralized rural photovoltaic system accessing to rural grid.The thesis takes study for photovoltaic system,and describes the background and current situation,and also discusses the technology characteristics of grid connected photovoltaic system.It also analyzes the structure of distribute photovoltaic systems,modules,inverters.And then analyzes the selection of photovoltaic modules,photovoltaic module array,photovoltaic inverter,wiring scheme,photovoltaic system connected to the rural power-grid.Finally,the thesis also analyzes the design scheme,operation monitoring,economic and social benefits of two photovoltaic systems.In the end,the thesis discusses the future of photovoltaic system alleviate poverty work.
