The invention discloses a combined Magnus wind-driven generator. The wind-driven generator is suitable for maritime environment and comprises a Magnus wind machine body, a marine triangular pile foundation and helical propeller blade vertical shaft wind-driven generators. The wind energy utilization rate of the Magnus wind machine can reach 55%, on the premise that each leaf blade rotates around the axis of the leaf blade at a high speed, a whole rotor disk is rotated to generate torque, and a part of electric energy is consumed. The Magnus wind-driven generator fully utilizes the stable triangular pile foundation, and the helical propeller blade vertical shaft wind-driven generators having a good starting property and a less wind direction effect are mounted to supply electricity for leaf blades of the Magnus wind machine, so that the torque of the whole machine is generated at an incoming flow wind speed, and the electricity generation is smooth. For the Magnus wind machine, a complicated variable pitch control mechanism is not required, and the Magnus wind machine also has a higher adaptive capacity under a severe sea condition, so that the Magnus wind machine has a favorable transformation and application prospect in the aspect of marine wind energy development.
