Photovoltaic array power function model and its simulation device

Based on the most popular photovoltaic array engineering mathematical model,a photovoltaic array power function model,which is a new type of mathematics model,is deduced,and it has been applied to the design of PV array simulator.The simulator control unit complete data analysis,processing and real-time control by IPC.Photovoltaic array output is simulated when light intensity and temperature change,and photovoltaic array characteristic curve can be real-time display.The test results show that the simulator can adjust output rapidly to track photovoltaic array IU characteristic curve according to load equivalent impedance changes,performs a good dynamic response,and plays a very good reference function for the research of PV array simulator.
