Wind tower foundation is the base component of wind turbine towers. Wind Tower Foundations not only bear the complete weight of hundred meters high wind tower and the upper wind turbine, but also host all the stress states under wind turbine vibration, and the extreme weathers like: earthquake, strong wind, etc. The stiffness of [...]
Over the past decade, global warming has becoming the main focus of the entire world, sea level rise, climate change, the health and living quality of human beings are being threatened by it. In order to maintain sustainable development of the world, green energy development becomes the key energy policy of the different governments [...]
The first offshore wind farm was successfully built and went into service in Denmark in 1991. The wind farm is consist of 11 wind power generating systems with an installed capacity of 450kw each. When stepping into the 21 century, every one has to face the severe energy and ecological conjuncture, which brings renewable [...]
Wind turbine tower is the support component of the complete wind power generating system, but it is not just a steel pole which gives the wind turbine a certain height. In order to transport the electricity that the wind turbine generated back to the underground grid, it needs some cables to connect the wind [...]
Wind is a kind of natural phenomena on earth, it is made of the heat from solar radiation. It is estimated that just about 2% of solar energy that reaches the earth can be transformed into wind energy, but the total quantity is still considerable. There is about 2.74×109MW wind energy in the world, [...]
Wind energy is a type of solar energy. Because of the unevenly sunlight distribution, the uneven atmosphere pressure distribution has been created. Therefore, the air moves under the action of atmosphere pressure, and wind has been generated. With modern wind turbine technology, wind can be turned into electricity, which is one of the cleanest [...]
Wind turbine tower is the key supporting part for the wind turbine system, it bears the force of wind on the blades, like thrust, torque, bending moment, and vibration of the electrical machine. wind turbine tower is composed of 3 or 4 section of straight cylinder or conic cylinder which are connected together with [...]
With the development of renewable energy, wind energy has been appreciated worldwide, as its characteristics of clean, recycled, renewable, and abundant sources, etc. In order to improve the environment problem and release the country from high fossil oil dependence, the national governments encouraged the investors to build wind farms to generate electricity instead of [...]
As the renewable energy, wind power development rapidly and gradually becomes the an important component of sustainable development strategies in many countries. Wind turbine equipment mainly consist of blades, wind turbine generator and wind turbine tower, among them, wind turbine tower is the support structure of wind turbine generator, also an essential part of [...]
Wind energy is a kind of resource which is friendly to the environment and inexhaustible, there are so many areas can get wind energy, like the northwest, northeast and coastal areas of China. Wind energy industry prospect is very broad, nowadays , we can see that the speed of development is getting faster and [...]
