According to the present invention, a plurality of buoy levers (104a, 104b) for wave power generation and front and rear variable wings (105a, 105b) for tidal power generation are interlocked in one direction, by an interlocking gear unit (103) that connects a driving shaft (102) of a power generator (101) and interlocking shafts (103a, 103b), to synergistically combine wave power and tidal power energy in the one power generator (101), thus making it possible to achieve hybrid power generation that maximizes efficiency at low cost. In particular, a mooring power generation facility is designed as a wave-resistant structure in which buoys and the power generator (101) are only partially exposed above the sea surface, and thus can safely generate power even in the presence of strong typhoons and rough waves.
