Distributed photovoltaic cleaning period determination method and system, medium and equipment

The invention discloses a distributed photovoltaic cleaning period determination method and system, a medium and equipment, and belongs to the technical field of distributed photovoltaic operation maintenance, for each group of photovoltaic arrays, when one of the photovoltaic arrays reaches a cleaning period, the photovoltaic array is cleaned, and after the photovoltaic array is cleaned, the cleaning period of the photovoltaic array is acquired. The output power of all the photovoltaic arrays at a set moment; determining the relative generating capacity of each uncleaned photovoltaic array and each cleaned photovoltaic array according to the output power of all the photovoltaic arrays at the set moment; and for each uncleaned photovoltaic array, taking the relative generating capacity of the uncleaned photovoltaic array and the cleaned photovoltaic array as the bottom, taking the logarithm of the cleaning power threshold value of the uncleaned photovoltaic array, and multiplying the obtained logarithm value
