The invention relates to a novel marine power station, especially involves a marine floating-type power station capable of utilizing wind energy, ocean current energy and wave energy. The structure comprises: a central pontoon, a suspension cabin, a universal elastic support, a wind turbine, a wave power plant, a connecting arm, a stabilizing pontoon, a water turbine, an energy storage device, an electricity generation system, etc. The power station employs a H-type vertical shaft wind wheel in major diameter and low height and a structure of upper-light, lower-heavy and elastic support in the middle, therefore the power station can float and be fixed on the sea; the power station also employs a centralized hydraulic pressure storage device consisting of an accumulator and a fuel tank, and a parallel-type generating system consisting of a plurality of generators and hydraulic motors, so as to guarantee the generating efficiency and the constant frequency under the condition of low wind speed, low flow velocity and small waves; the power station is suitable for the comprehensive utilization of deep sea wind energy, wave energy and ocean current energy resource.
