Problems solved by technology

However, most of the current research work focuses on a single offshore renewable energy source
Moreover, due to the harsh marine environment, wave energy and tidal current energy generating devices operate in the ocean. If there is no stable platform to carry them, when the storm surge comes, the floating generating devices are easily damaged, causing huge economic losses and safety. Hidden danger

Embodiment Construction

[0018] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Schematic diagram of the offshore renewable energy integrated power generation system figure 1 As shown, the monopile structure 1 is fixed on the seabed, and a horizontal-axis fan 2 and a first direct-drive permanent magnet generator 3-1 are installed on the top. The main shaft of the horizontal axis fan 2 is directly connected with the rotor of the first direct-drive permanent magnet generator 3-1, and the blades of the fan capture wind energy to rotate and directly drive the generator to generate electricity. The part close to the sea surface is equipped with a wave energy power generation device placed parallel to the direction of wave movement, which consists of three buoys (front buoy 7, middle buoy 8, rear buoy 9) and a wave energy power generation hydraulic system 4, the buoys follow Wave movement, converting wave energy into mechanical energy for buoy...

Abstract

The invention relates to an offshore renewable energy source comprehensive power generating system, belonging to the technical field of renewable energy source power generation. The comprehensive power generating system comprises a single pile structure (1), three power generating devices and an electrical connecting circuit. The three power generating devices comprise a wind power generating device, a wave energy power generating device and a tidal energy power generating device which are respectively connected with a direct-current bus (19) in the comprehensive power generating system in parallel by three direct-drive permanent magnet generators (3-1, 3-2, 3-3) and three rectifiers (16-1, 16-2, 16-3), and connected to a reverser (21) on the bank by a seabed cable (20), and finally merged in a power grid by a boosting transformer (22). The offshore renewable energy source comprehensive power generating system can integrate the offshore wind energy power generation, wave energy power generation and tidal energy power generation to an organic combined body, and realizes the compatibility of various power generating devices and the credible connection of various power generating devices with the power grid by the electrical connecting system.

Description

technical field [0001] The invention relates to an offshore renewable energy comprehensive power generation system, which belongs to the technical field of renewable energy power generation. Background technique [0002] The ocean covers 70% of the earth's surface and contains infinite energy. It is estimated that the sum of its energy greatly exceeds the current global energy demand. Because the deep sea is usually far away from the continent, it is difficult to use deep sea energy under the existing technical conditions, so the available ocean energy is mainly distributed in the offshore. Offshore energy is clean and renewable energy, and its scientific development and utilization are of great significance to alleviate energy crisis and environmental pollution. [0003] Currently available offshore renewable energy mainly includes offshore wind energy, wave energy and tidal current energy. In recent years, a lot of research work has been carried out on offshore renewable...
