Offshore wind power generation foundation capable of realizing self balance and wind turbine generator system

Abstract

The invention discloses an offshore wind power generation foundation capable of realizing self balance and a wind turbine generator system. The offshore wind power generation foundation comprises a floating platform, a photoelectric conversion device, a water supply hose and a self-balance mechanism; the self-balance mechanism comprises at least three self-balance modules; the self-balance modulescomprise floating bodies, water flow driving pieces, and balance arms provided with water jet channels; water inlets of the water jet channels communicate with the other end of the water supply hose;the balance arms comprise connecting ends and floating ends; the connecting ends are connected with connecting lugs; the floating bodies are arranged on the floating ends; and the water flow drivingpieces communicate into the water jet channels, and are electrically connected with a control device. The balance arms can obtain reactive force, generated by scouring force, to form lateral support on a fan foundation, so that the fan foundation realizes automatic gesture correction, the self-adaption adjustment of the balance state of a wind driven generator can be realized under the precondition of avoiding use of cables, and the overturning of the wind driven generator due to impact and influence from various limit loads such as oceans, currents, wind, waves and the like is prevented.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generators, in particular to a self-balancing offshore wind power generation foundation and a wind power generator set. Background technique [0002] With the rapid development of science and technology, and the country's continuous advocacy of the development and application of new energy and new technologies, many non-polluting, low energy consumption, and low-cost energy sources are gradually widely used, such as wind energy. At present, wind power generators use the most wind energy, and offshore wind power generators are the most widely used. However, due to the harsh and complex operating environment of the ocean, offshore wind turbines are impacted and affected by various extreme loads such as ocean, current, wind, and waves, resulting in excessive torsional loads and excessive yaw motions. This will very likely cause the offshore wind turbine to capsize, affecting the reliabil...

AI Technical Summary

Problems solved by technology

However, due to the harsh and complex operating environment of the ocean, offshore wind turbines are subjected to the impact and influence of various extreme loads such as ocean, current, wind, and waves, resulting in excessive torsional loads and excessive yaw motions. This will very likely lead to the overturning of offshore wind turbines, affecting the reliability, safety and normal use of offshore wind turbines, resulting in huge economic losses

Most of the existing offshore wind turbines are connected to the seabed by cables, and the purpose of preventing overturning is achieved through this kind of rigid connection protection structure, and then the cables are usually made of metal materials, which can survive for a long time in complex and harsh marine environments. Erosion is very likely to cause corrosion damage or fatigue fracture. At the same time, offshore wind turbines and cables are subjected to large torsional loads, severe yaw motions, and low reliability; the installation of cables is difficult and the initial investment cost is high.
