Abstract

The invention discloses a double-side built-in V type permanent magnetic linear generator, a seabed type wave energy power generator based on the linear generator and a control method. The double-sidebuilt-in V type permanent magnetic linear generator is applied to the seabed type wave energy power generator; according to the phase relation between the wave force, in the vertical direction, bornby the seabed type wave energy power generator and operation speed of the generator, phase analysis and area division are carried out, a damping coefficient variable method is used to adjust the amplitude of an electromagnetic force of the linear generator in real time, so that the resultant force phase of the generator is synchronized with the operation speed phase of the same, and further, the operation efficiency of the seabed type wave energy power generator is maximized; and when the sea waves are relatively high, a maximal damping coefficient method is used so that the linear power generator outputs the maximal electromagnetic force, a system device is prevented from damage on the structure, and the safety and stability of the whole system device in the operation process are improved.

Description

technical field [0001] The invention relates to a bilateral built-in V-shaped permanent magnet linear generator, a seabed wave energy generating device and a control method based on the linear generator, and belongs to new energy power generation technology. Background technique [0002] In the past two years, with the gradual increase of environmental pollution control in my country, converting clean and renewable energy into electric energy has become the main way to improve my country's environmental quality and meet the needs of national production and life for electric energy. Among them, the submarine wave power generation technology, as one of the ways to convert clean and renewable energy into electric energy, provides power support for the development of my country's marine economy while providing electric energy for remote islands, offshore platforms and coastal areas. [0003] However, with the in-depth research on submarine wave energy generation technology and t...

AI Technical Summary

Problems solved by technology

[0003] However, with the in-depth research on submarine wave energy generation technology and the successive construction of test and test projects, two problems have gradually been discovered: First, due to the special existence of wave energy, it is difficult to improve the natural operating state of the submarine wave energy generation device. Second, due to the extreme marine environment (hurricane, typhoon, etc.), the safety and stability of the submarine wave energy generation device in the ocean waves cannot be guaranteed.

[0006] Generally speaking, the existing wave energy generation devices mainly have the following disadvantages: poor practicability, failure to take into account the operating efficiency and safety and stability of the system device; additional control system equipment is required, which makes the system structure of the wave energy generation device change. The complexity is not conducive to the installation and later operation and maintenance of the system device; there is no refinement and analysis of the operation process of the wave energy generation device, and there is still a lot of room for improvement to maximize its operating efficiency
