Modeling the PV generator behavior submit to the open-circuit and the short-circuit faults

Résumé

— In this paper, we proposed a new mathematical model of a faulty photovoltaic generator operation. It presents its behavior, when it's subjected to the open-circuit and the short-circuit faults at its basic components as: cells, bypass diodes and blocking diodes. Such kind of modeling will allow developing fault detection and diagnosis methods. Indeed, the proposed model will be used to set normal and fault operation conditions database, which will facilitate learning and classifications phases. NOMENCLATURE PV = Photovoltaic Generator. phi = Photocurrent. V Cell_Open-circuit = Open-Circuit Voltage of Cell. I Cell_Short-circuit = Short-Circuit Current of Cell. I 0 = Reverse Saturation Current of the Diode. R S = Cell Series Resistance. R SH = Cell Shunt Resistance. nc: ncg / ncp = Cell Number: Good / Defective. ng: ngg / ngp = Group Number: Good / Defective. nm: nmg / nmp = Module Number: Good / Defective. ns: nsg / nsp = String Number: Good / Defective. nfg / nfp = Good / Defective Generator. N Cells = Cells Number in each Group. N Groups = Groups Number in each Module. N Modules = Modules Number in each String. N Strings = Strings Number in the Generator. V / I = Voltage / Current. P = Power. V Cell_imposed = Voltage Imposed. DTV = Diode Thermal Voltage. a = Diode Ideality Factor.
