Design And Operation Of Solar Photovoltaic Power Station System

Solar energy,as a kind of green renewable energy,is concerned by many people at home and abroad because it meets the demand of sustainable development.This makes solar power generation technology become a hot topic in the world.With the continuous progress of China's society and the rapid development of economy,the contradiction of China's energy structure has become increasingly prominent.How to guarantee the power supply quality and reliability of the power grid on the basis of energy consumption has become an urgent problem to be solved.Solar photovoltaic power generation system is widely used in the process of operation because of its own advantages and does not produce any pollution.Therefore,it can be said that solar photovoltaic power generation is a major trend of future development.This article is based on this study,the first analysis of research background and significance of the photovoltaic power station,and then to summarize the existing research literature,understand the current status of domestic and foreign study of solar photovoltaic power generation,so as to lay a good theoretical basis to the research of this paper,also provide theoretical reference for future research,after the study of this article structure is analyzed and summarized,the research content of this article.The performance of the solar energy system in operation,such as the output characteristics,is calculated and introduced in detail,and then the requirements of power quality,etc.are analyzed and introduced briefly after being connected to the power grid.This paper focuses on the overall design of pv power station system,including the selection of design scheme.Through the selection and introduction of 4MW pv power station construction,it provides the foundation for the construction of pv power station in the future.Then from the access mode of power system,the connection mode of the photovoltaic power station is determined,and then the design of the primary and secondary electricity is carried out.According to the calculation in this paper,the annual capacity of the entire power station is 7222.52 MWh in an ideal state.At the end of this paper,the operation state of pv power station after grid-connection is analyzed to understand its impact on power grid operation,and the isolated effect of grid-connection is expounded.At the end,the operation efficiency of pv power station after grid-connection is analyzed and calculated rationally.
