Pv Arrays Simulator Research And Design Base On IPC

Fossil energy sources dried up increasingly around the world，fossil fuels in use releaseof greenhouse gases that cause global warming and pollution of the environment, So countriesaround the world pay more and more attention to the development and utilization of greenenergy. Countries to one of the focuses of research on green energy is to use solar power.Photovoltaic (pv) devices in the process of research and development, performance testingrequires Photovoltaic modules output as input. High-power photovoltaic componentsexpensive, covers an area of large,The power output is influenced by the environment，Can’tmeet Photovoltaic (pv) power generation equipment needs in the development process. Inorder to get rid of the trouble Scholars at home and abroad puts forward the concept ofPhotovoltaic (pv) array simulation. Use Pv array simulator instead of the traditionalphotovoltaic modules increases the flexibility of the experiment. Research and developmentof pv arrays simulator Upon the hardware foundation for Development of photovoltaic powergeneration equipment.This paper first introduces the global pv industry development presentsituation.Introduced The research status of pv arrays simulator about home andabroad.Summarizes the characteristics of digital and analog pv arrays simulator andapplications.Compared with the earlier analog pv arrays simulator.The development ofmodern power electronic technology and the improvement of control technology Make digitalpv array emulator becoming a hot spot of research.In this paper, we discussed severaltypical digital pv array emulator and analyze its possible deficiencies.Finally determine theproject implement of simulatorSimulator realize is the theoretical basis of PV mathematical model. The simulatorOutput using the mathematical model for real-time calculation. As an output control by themathematical model should be On the premise of meet the accuracy requirement，conform tothe principle is simple and convenient programming model. Then the paper studies the working principle of silicon pv modules and physical mathematical model. Discussed severalcommon pv array engineering using mathematical model. the precision of engineeringmathematics model is high but the model is very complicated and There is several times ofIndex operation, Is not conducive to programming and the controller calculation,this paperbase on the most widely applied Photovoltaic (pv) array mathematical model. A new type ofengineering mathematics model is deduced-Pv array power function model, and applied it tothe Pv arrays simulator design.Papers under the matlab/Simulink comparison the simulation model of power functionmodel and exponential model Verify the correctness.Using Simulink for simulation thesimulator control method.Upper machine computing and real-time display and lower machinecircuit of power control composition the pv arrays simulator main circuit adopts the modulardesign,to achieve the pv modules for different power output characteristic simulation.Thepaper in the same conditions compared the Photovoltaic modules output and the emulatoroutput Verify the validity of the simulator design.
