Zusammenfassung:The invention provides a photovoltaic array arc fault positioning method and device, electronic equipment and a storage medium. The method comprises the steps that an electromagnetic radiation signal generated by an arc in a photovoltaic array and the irradiance of the environment where the photovoltaic array is located are acquired; determining the intensity of an electromagnetic radiation signal generated by the arc; inputting the intensity and irradiance of the electromagnetic radiation signal into a trained distance prediction model to obtain a first distance from the electric arc to the first antenna and a second distance from the electric arc to the second antenna; for each planar grid unit divided by the photovoltaic array, calculating a third distance from the central point of each planar grid unit to the first antenna and a fourth distance from the central point of each planar grid unit to the second antenna; and according to the first distance, the second distance, the plurality of third distances a
