Abstract

The invention provides an offshore solar energy, wind energy and wave energy complementary power generation device. The offshore solar energy, wind energy and wave energy complementary power generation device comprises a wave energy capturing device, a wind energy capturing device, a hydraulic transmission system, a solar photovoltaic panel, a power conversion system, a floating platform upper-layer deck, a floating platform lower-layer deck, a supporting column, an underwater buoyancy tank and a mooring system. The hydraulic transmission system is composed of a wave energy conversion hydraulic subsystem and a fan hydraulic subsystem. The wave energy capturing device and the wind energy capturing device are connected with the two subsystems correspondingly to drive a generator to generatepower, and are combined with electric energy generated by the solar photovoltaic panel through the power conversion system to form a microgrid, and the electric energy is stored in an energy storage device or directly supplied to a user. Main oil ways of the wave energy conversion hydraulic subsystem and the fan hydraulic subsystem are connected through communicating pipelines, and connection anddisconnection of the two main oil ways are controlled through a cartridge valve. When resources are good, the two subsystems operate independently; and when the resources are poor, the two subsystemsoperate in a complementary mode to drive the generator to generate power.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to an offshore solar energy, wind energy and wave energy complementary power generation equipment. Background technique [0002] At present, offshore working platforms and offshore islands mainly rely on diesel generators for power supply, which is not only costly but also easy to cause pollution. The development of offshore renewable energy power generation plays an important role in solving island residents' daily electricity consumption, offshore exploration, and building ecological islands. significance. When developing an offshore renewable energy power generation platform, the cost of the platform is high, and the area is not easy to be too large, so it is necessary to consider improving the energy utilization rate as much as possible in a limited space. In addition, the offshore environment is harsh, which puts forward high requirements on the survivability of the p...
