Description
TOWER FOR WIND POWER GENERATION
The present invention belongs to the technical field of wind power generation, particularly relating to a tower for wind power generation.
Background Technology
Energy drives the development of modern society, continuously improving people's lives. However, traditional energy sources will eventually be depleted.
Improving energy structure and utilizing new and renewable energy sources have become hot topics in the global energy industry. In the development of new energy, wind energy has seen rapid growth worldwide due to its short construction cycle, low environmental requirements, abundant reserves, and high utilization rate. Wind energy is currently the most promising and technically mature new and renewable energy source. Wind power generation is a low-emission, low-pollution, and low- carbon power production mode that effectively reduces carbon dioxide emissions and helps mitigate global warming. Thus, it has become an important choice for sustainable development of electric power in various countries. The utilization of wind energy is mainly through wind power generation.
A wind turbine generator set includes a wind wheel, a generator; the wind wheel comprises blades, a hub, and reinforcing components. It has functions such as generating power by rotating blades under wind force and rotating the generator head.
A wind power generation source consists of a wind turbine generator set, a tower supporting the generator set, a battery charging controller, an inverter, a load controller, a grid-connected controller, and a battery pack.
As a main structure for wind power generation, wind turbines are gradually developing towards high power. The issue of wind-induced damage under strong typhoons is becoming increasingly prominent. China, located on the west coast of the
North Pacific Ocean, has many wind farms concentrated in the southeast coastal areas,
which are rich in wind energy resources. However, these areas are affected by dozens LUs076T of typhoons each year, causing significant loss of life and property, and wind turbines are also damaged by strong typhoons. The tower, as the main structure for wind power generation, can sway under strong winds, potentially collapsing when the swaying is severe, causing unnecessary losses. Moreover, the tower is mostly of an integral structure, making transportation and installation inconvenient.
Currently, one of the urgent problems to solve is how to improve the wind resistance of wind turbine structures. Increasing the wall thickness of the tower can enhance its wind resistance, but it also significantly raises investment costs, increases the structural weight, and complicates construction, leading to a series of potential risks. However, the uncontrollable nature of the tower does not fundamentally improve the stability of the wind turbine system.
