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.
Various factors can contribute to arc faults in a photovoltaic system, such as loose connections, inadequate breaker maintenance, broken cables, aging or damaged insulation materials, or the presence of damp and corrosive wires. Due to the numerous wires on the DC side of the PV system, arc faults are more likely to occur.
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.
2.Solax’s solution In order to prevent the arcing of the DC side of the inverter from causing fires and other hazards, SolaX engineers have developed the integrated AFCI function, which detects the arcing of the DC side and cuts the circuit in time to protect the user and the electrical system.
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.
In a PV system, arcs may be caused by loose terminals, poor contact, broken cables, aging, carbonized, or damaged insulation materials, or damp and corrosive wires. Electric arcs are likely to occur as there are many wiring terminals on the DC side of the PV system. Figure 1-4 shows the types of arcs that may be generated in a PV array.
