Building a Demonstration Model of a Micro Photovoltaic Power Plant

V diplomi predstavim teoretični in praktični del izdelave enostavnega modela fotonapetostne elektrarne. Prikažem fizikalni potek pretvorbe sončne energije v električno in kemično energijo, delovanje fotovoltaičnih celic, lastnosti in delovanje akumulatorja, način regulacije polnjenja ter opišem praznjenja z enosmernim in izmeničnim porabnikom. Izmeril sem dolžino praznjenja akumulatorja, ki se polni preko FV modula in regulatorja polnjenja. Z merilnim analizatorjem sem izmerili obliko inducirane napetosti in toka na sponkah bremena in kakovost električne energije.The thesis presents theoretical and practical aspects of the calculation and modelling of micro photovoltaic power plant. It presents physical process of converting solar energy into electrical and chemical energy, operation of photovoltaic cells, batteries, controlling the charging and discharging of the DC and AC consumers. I measured the charging length of battery that is charged threw the photovoltaic module and the charge controller. With quality analyser I measured the shape of the induced voltage and current at the terminals of the load and power quality
