The invention discloses a smoothing reactor parameter determination method and device, equipment and a storage medium. The method comprises the steps that a first reference reactance value is determined according to a first parameter influencing direct current fluctuation during normal operation; determining a second reference reactance value according to a second parameter influencing direct current fluctuation during bridge arm direct connection; determining a third reference reactance value according to a third parameter which affects the interruption of the direct current during light load; determining a fourth reference reactance value according to a fourth parameter which affects the change of the fault current when the DC line has a fault; determining a reactance design value of the smoothing reactor according to the maximum value of the first reference reactance value, the second reference reactance value, the third reference reactance value and the fourth reference reactance value, and determining a
