Independent power generation system from water waves and method based on ship navigation

Abstract

The invention provides an independent power generation system from water waves based on ship navigation. The independent power generation system comprises a ship power system, a water wave power generation system comprising a water immersion determination module, a power rotating wheel installation module, an electromagnetic induction power generation module, a variable voltage power supply or accumulator electricity-storage system comprising a transformer power module or an accumulator energy-storage module and a ship daily life electricity consumption system. The invention further discloses a power generation method of the above power generation system. Ship navigation drives water waves to generate power such that fuel energy is saved. Meanwhile, water wave energy is converted to electric energy and stored into an accumulator, thereby keeping living electricity consumption of a ship. During ship navigation, efficiency of power generation is the highest by controlling ship speed and allowing the speed to be one of optimal value. The independent power generation system from water waves and the method based on ship navigation have following beneficial effects: by depending on power of water waves, the ship can generate power on its own so that efficiency of power generation is the best; energy consumption of other energy for the ship is reduced and therefore the ship is more cost-effective and eco-friendly.

Description

technical field [0001] The invention relates to the field of ship power generation, in particular to a water wave autonomous power generation system and method based on ship navigation. Background technique [0002] With the rapid development of the economy, the increasing demand for energy, the increasing shortage of traditional energy sources, and the use of a large number of fossil raw materials have caused serious ecological and environmental problems, which have become the focus of attention all over the world. In order to deal with resource depletion and ecological environment problems, and to solve the bottleneck problem of energy supply in social and economic development, it is urgent to find alternative renewable energy sources. Ocean energy is a kind of renewable energy stored in the ocean, including natural resources such as temperature difference energy, ocean current energy, wave energy, tidal energy, and offshore wind and solar energy. Among them, ocean wave e...

Problems solved by technology

The advantage is that there are fewer moving parts of the device, the overall stability is high, the reliability is good, the wave energy conversion efficiency is high, the maintenance cost is low, and the system power output is stable in big waves; the disadvantage is that the system conversion efficiency in small waves is low. Low

Its advantages: high conversion efficiency, adjusting the center of mass of the duck body can make its own frequency the same as or close to the frequency of wave motion, thereby forming resonance, which can achieve the maximum conversion efficiency; disadvantages: complex equipment resulting in poor reliability, especially in In the harsh marine environment, the device is easily damaged

However, the scale of China's wave power generation device demonstration tests is much smaller than that of Norway and the United Kingdom, and the types of test development methods are far less than those of Japan, and there is still a certain distance from the practical use of small devices, and the stability and reliability of device operation need to be improved.
