Design Of 10MW Photovoltaic Power Generation Project

With the rapid development of the economy,huge energy consumption has become the primary issue.It is a trend to replace traditional energy with new energy.Among all new energy sources,solar energy has its unique advantages.This thesis aims to design a photovoltaic power generation system according to the needs of a certain project.The most important part of the design is the calculation of solar radiation.In this thesis,several models of monthly radiation are introduced firstly.Based on the specific position of the project,an isotropic model is selected as the theoretical basis for the calculation.Then,depending on the data of the Meteorological Agency,the radiation values with tilt angle range of 31° to 50° in 12 months are calculated,and the optimal tilt angle is 37°.After that,it is verified by the software of Meteonorm7.The results show that the optimal tilt angle of the software is in good agreement with the theoretical calculations.Therefore,the optimal tilt angle is 37°in this project.Next,the selection and configuration of the system equipment are introduced,including solar cells,inverters,transformers,etc.,and the components and connection of the entire system are given.Finally,according to the theoretical model and selected equipment,the estimated annual power generation is calculated,that meets the requirement of design.At the same time,the benefits of the project are analyzed briefly.Combined with local meteorological data,this method can be applied to photovoltaic power generation projects in other regions.It will has certain reference value for future design.
