In photovoltaic systems, parasitic capacitance is often formed between PV panels and the ground. Because of the switching nature of PV converters, a high-frequency voltage is usually generated over these parasitic
Arc detection in PV inverters must include a method for predicting the occurrence of arcing, either just before the occurrence of a sustained arc or very early in the in the lifetime of the sustained arc, where the source of the arc can be shut off.
Because the PV inverter works in a high−frequency pulse width modulation (PWM) control mode, the arc fault detection is prone to nuisance tripping due to PV inverter noises. An arc fault detection method based on the autoregressive (AR) model is proposed.
The photovoltaic DC detection method utilizes the characteristics of arc light, arc sound, and electromagnetic radiation to monitor fault arcs in photovoltaic systems [13, 14, 15]. This specialized approach employs dedicated sensors for detecting arc light, sound, and electromagnetic radiation generated by the arc.
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.
Therefore, the development of effective arc detection methods and standards is crucial for ensuring the safe and reliable operation of PV systems [11, 12]. The photovoltaic DC detection method utilizes the characteristics of arc light, arc sound, and electromagnetic radiation to monitor fault arcs in photovoltaic systems [13, 14, 15].
To address this issue, the National Electrical Code (NEC) in the United States, specifically in Article 690.11, requires photovoltaic systems with DC voltages exceeding 80V to be equipped with fault arc detection devices and circuit breakers .
