The whole generating device adopts a modularization combined design, and thus the unit cost and the marine transportation construction cost are reduced. The multifunctional integrated hydraulic-drive generating device provides a high-cost-performance ocean energy development mode, the generated electricity is stable and can be combined to a power grid, supplied to an offshore facility or be applied to off-island power supply, and thus the multifunctional integrated hydraulic-drive generating device has high economic values and important social effects.

Description

technical field [0001] The invention relates to comprehensive development and utilization of marine renewable energy, and belongs to the field of marine engineering marine renewable energy. Background technique [0002] The vast ocean contains infinite clean and renewable energy, scientific and efficient development and utilization are of great significance to alleviate the energy crisis and environmental pollution problems. There are various types of ocean energy, mainly including offshore wind energy wave energy, tidal energy, tidal current energy, and temperature difference energy. However, the offshore operating environment is harsh and changeable, the wind and waves are random, and the energy is large and small, resulting in unstable marine power generation. Traditionally, complex speed control or energy storage devices are used. The ocean energy density is low and scattered, and the capacity of a single unit of a single energy conversion and utilization method is low ...

Problems solved by technology

However, the offshore operating environment is harsh and changeable, the wind and waves are random, and the energy is large and small, resulting in unstable marine power generation. Traditionally, complex speed control or energy storage devices are used.

The ocean energy density is low and scattered, and the capacity of a single unit of a single energy conversion and utilization method is low and the efficiency is low

Submerged in the tidal current energy generator set due to seawater seepage into the corrosion motor, and the use of complex waterproof technology, resulting in increased costs
