Automated Fault Management System in a Photovoltaic Array: A Reconfiguration-Based Approach

This work proposes an automated reconfiguration system to manage two types of faults in any position inside the solar arrays. The studied are short-circuit ground and open wires string. These were selected because they severely affect power production. By identifying affected panels isolating faulty one, it is possible recover part loss. Among other that can detect locate are: diode short-circuit, internal open-circuit, degradation parasitic serial resistance. detect, above faults, switch distributed commutators most Moreover, return automatically previous state when fault has been repaired. A SIMULINK model built prove this automatic system, a simulated numerical experiment executed test response mentioned. results show recovery more than 90%, diagnosis accuracy sensitivity both 100% for experiment.
