The invention discloses an active heave compensation control system and an active heave compensation control method of a marine ship-borne AC variable-frequency winch. The control system comprises a hot backup redundant controller, a frequency converter group, an AC variable-frequency motor, a transmission planet gear train, an armored umbilical cable, a coiling block and a signal detection sensor; the signal detection sensor is used for sensing the rotating speed of the coiling block and the heave acceleration of a mother ship; the signal output end of the signal detection sensor is connected with the hot backup redundant controller and sends the acquired signals to the hot backup redundant controller; the hot backup redundant controller is connected with the AC variable-frequency motor by use of the frequency converter group; the AC variable-frequency motor is connected with the transmission planet gear train by use of a speed reducer; the transmission planet gear train is fixedly connected to one end of the coiling block; the armored umbilical cable is wound around the coiling block; the free end of the armored umbilical cable is connected with a deep sea operating apparatus. The control system is simple in structure and has an active heave compensation control function.
