Research On Maximum Generating Capacity Of PV Power Generation System

With the ecological pollution and the energy crisis intensifies, the whole world istrying to find a non-breaking change the environment and sustainable newenergy.Therefore, the photovoltaic power generation with broad space fordevelopment,PV technology is not only a supplement of today’s society’s energystructure,And is likely to become the main force of the future energy mix.The PVsystem is a large investment, low efficiency,reducing the value andcost-effective.Therefore, improving the overall efficiency of the PV system,so that thesolar PV system to obtain the maximum amount of power the subject is particularlyimportant.In this paper, the work done can be summarized as follows:First, this thesis introduces the development situations and research backgroundin the word. Then analysis and presentat the PV systems and PV cells. Meanwhile,thesis discussed the application of PV power generation system,Combined with theauthor has been involved in of Beijing Yanqing projects and BNBM pressure B theregulator station project, were analyzed BIPV, small PV power station, as well aslarge and medium-sized grid-connected PV power station.Secondly, this thesis built solar radiation calculation model of inclined plane andpower output model of photovoltaic cell.Based on the Geermu local geographical andmeteorological data set, a new idea calculated hourly solar radiation to determine theoptimal angle of PV modules.This thesis analysis the variation of the optimum tiltangle from the network system and grid system,and proposed a method to find thebest angle called Arithmetic Optimization Method. Proof that off-grid systemsinstalled Golmud optimal angle of60degrees, Grid systems is optimal angle of35degrees. The various regions of the PV system design provides a design reference.Again, combined with the author who took part in the project,thesis describesand analyzes the principle and operation mode of the flat uniaxial, biaxial and obliquesingle-axis tracking system, to track the motion of the system model.By PVsyst simulation software,this thesis simulate the Different types of tracking systems of0.5MWp in geermu and get the conclusion, and demonstrate system performance andapplication value.Finally, on the basis of the previous chapters conclusion, Combined with theauthor has been involved in projects,20MW photovoltaic power plant analysis anddesign. After analysis of the power generation operations related data, and proved thatusing the35degree angle installed generating capacity max.
