Abstract: A wave-wind mutually supplementing power supply system for continuous power generation is disclosed. The system of the present invention has a wave kinetic energy module (10), which comprises a wave energy harnessing unit (100), a transmission shaft (110), a generator unit (120), a torque adjusting unit (130) and an automatic control unit (140). The wave kinetic energy module (10) is disposed on/in a sea and may generate electricity through the motion of sea water. The electricity so generated is combined with a wind power generation device to provide continuous power generation. The automatic control unit (140) has a microprocessor (141) and a sea water motion sensor unit (142) so as to adjust the torque of the transmission shaft and control the activation of the generator unit according to the motion of the sea water.
