The invention discloses a converter station equipment sound power level calculation method and system, equipment and a medium, and belongs to the technical field of power equipment noise evaluation.The calculation method comprises the following steps that sound pressure data around the equipment are measured, and a measuring point sound pressure frequency spectrum is obtained according to the sound pressure data; based on the geometrical relationship between the sound sources and the measuring points, obtaining the attenuation of sound propagation between each sound source and the measuring points; establishing a mathematical model between the sound source sound power level and the measuring point sound pressure level based on the measuring point sound pressure spectrum and the sound propagation attenuation; and obtaining the sound power level of the sound source equipment based on a mathematical model between the sound power level of the sound source and the sound pressure level of the measuring point.
