Abstract

The invention discloses an offshore wind and wave complementary generating system and belongs to the technical field of energy development and utilization. The invention is used for overcoming a defect that a single offshore generating set is instable. The offshore wind and wave complementary generating system comprises a wind energy conversion device, a wave energy conversion device and a hydraulic conversion system, wherein the wind energy conversion device and the wave energy conversion device are respectively connected with the hydraulic conversion system; the wind energy conversion device is used for converting wind energy into mechanical energy and transmitting the mechanical energy to the hydraulic conversion system; the wave energy conversion device is used for converting wave energy into mechanical energy and transmitting the mechanical energy to the hydraulic conversion system; and the hydraulic conversion system serves as an energy conversion link and is used for convertingthe mechanical energy transmitted by the wind energy conversion device and the wave energy conversion device into hydraulic energy, superposing the hydraulic energy and driving a direct-drive generator to output electric energy. The stability of the output power of the offshore generating system is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of energy development and utilization, and in particular relates to an offshore wind and wave complementary power generation system. Background technique [0002] Due to the limitation of special geography and natural environment, there are many islands suitable for habitation or of great economic value distributed along the sea near the coast. Because it is far away from the power grid, the power supply has always been a barrier to the island's economic development and the improvement of residents' living standards. The independent power generation system has become the most needed power source in these places. At present, the common power supply on islands generally uses diesel to generate electricity. This kind of power supply is not only expensive, but also has low power generation efficiency, and also emits a large amount of harmful gases and smoke. Therefore, diesel generators can only be used as a sh...
