The present invention relates to an electric active heave compensation winch system in the special vessel technology field. The electric active heave compensation winch system comprises a cable arrangement mechanism disposed on a cable, a heave measuring unit for measuring heave velocity and accelerated velocity of a suspension point on a suspension point mechanism, a winch driving unit connected with a winch motor, a winch controller, and an energy processing unit used for energy recovery and utilization. Motion parameters of a vessel in a future short period are actively predicted based on history data and vessel heave motion data detected in real time, feedforward control of vessel motion velocity prediction is calculated, and feedback control of relative velocity of a load and the vessel and feedback control of position drift are simultaneously calculated.
