Contribución al desarrollo tecnológico de la protección de generadores fotovoltaicos en condiciones de falta

Resumo

This thesis presents an extensive review of causes, consequences and treatment operation in fault conditions of a PV generator, due to partial shading or electrical fault. The operation in these fault conditions poses a threat of overcurrent in the PV system, and can cause power quality problems in the network to which it is connected. Thus, it makes a normative study on electrical faults and power quality finding that no specific reference PV systems standards in both fields. One of the objectives achieved is the presentation of a proposal for overcurrent protection measures for a PV generator under fault conditions. Thus, we develop a dynamic simulation model of PV device (cell, module or generator) in Matlab/Simulink® to investigate the behavior of PV devices when operating under abnormal conditions, validating with experimental measurements on actual PV generator.
