Arc faults not only reduce the efficiency and reliability of the PV power generation system, but also may cause safety risks such as fire, which poses a threat to the safe and reliable operation of the PV system. Therefore, timely and accurate diagnosis of PV inverter arc faults is crucial.
DC arc faults may occur due to aging, damage or poor contact of internal components of the inverter. Arc faults not only reduce the efficiency and reliability of the PV power generation system, but also may cause safety risks such as fire, which poses a threat to the safe and reliable operation of the PV system.
Detecting these faults in advance is therefore vital, as it can inform the user of the failure of a PV system or directly shut down systems or components , . Consequently, an additional reliable detection device for DC series arc fault is crucial, least of all the rooftop PV systems.
Photovoltaic inverters, as key devices, play an important role in converting DC energy to AC energy. However, arcing faults may occur due to aging, damage, or poor contact of components inside the inverter.
Therefore, timely and accurate diagnosis of PV inverter arc faults is of great significance. This thesis review will introduce the methods, techniques, and related research results of PV inverter arc fault diagnosis, aiming to provide reference and guidance for the operation and maintenance of PV power generation systems.
The root cause is that the insulation level between the distribution line conductors is often higher than the insulation level of the line to ground. DC Series Arc of Fault Characterization. Of the serial parallel and grounding-type arcs, grounding-type arcs are more common.
