A wind turbine is a type of turbine that uses wind energy as its power. Normally, when the wind passes through a turbine, almost half the air is forced to stay around the blades instead of passing through them, and the energy in these winds is lost. The installation of wind turbines on building is not trivial, it requires careful consideration and a special mechanical study. The safety is also paramount before erecting a generator with blades that spin over 600 rpm.
Within the scope of blade maintenance, we can distinguish between preventive and corrective maintenance. The first is to implement periodic inspections to determine the state of the blade and to detect the presence of various damages or damages that require attention; minor damage (chipping, coating, surface cracks, oil or oil stains, etc.), severe damage (rolling damage, stringer removal, lightning strike, etc.)
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. They are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels.
Engineers have gone to great lengths to make wind turbines as exposed as possible, placing their blades on high towers on hilltops or in desolate, unprotected seas miles from shore. A new study presents an interesting curveball that could open up new avenues for renewable energy generation, demonstrating that turbines placed behind hills can actually produce more energy than those in open areas.
Can a wind turbine turn so slowly to generate electricity? Wind energy is a renewable and clean energy. With the continuous increase of human demand for energy, human beings gradually began to increase the use of wind energy. Wind turbines are often found on vast grasslands, hillsides and even on the sea. Why the blades of wind turbines turn so slowly, can it generate electricity?
In the early 1970s, due to the problem of energy shortage because of the oil crisis, people realized the instability and limitation of conventional fossil energy supply. So people began to seek clean and renewable energy. As a renewable and pollution-free natural energy, wind energy has attracted people's attention.
Frequent typhoons are a double-edged sword for offshore wind farms. A weaker typhoon can increase power generation and improve the economic benefits of the wind farm. However, a stronger typhoon will bring great harm to the wind farm. In order to better develop and utilize wind energy resources in offshore areas, how to reduce the damage caused by typhoons to wind farms will be an urgent issue to be considered in the development of offshore wind power.
A wind turbine is a power machine that converts wind energy into mechanical work. Generally speaking, it is a thermal energy generator that uses the sun's micro-heat source and the atmosphere as the working medium. Wind turbines use natural energy, which is much better than diesel power generation.
As wind turbine is very important and when there is troubles, it is not an easy case to deal with. Today, we are going to introduce 3 common troubleshooting of wind turbines to you. We hope that this article can help you.
With the development of science and technology, the types and numbers of wind turbine are increasing. As new units are continuously invested, the units must continue to age. The fault inspection of wind turbines is also becoming more and more important. Today, we will introduce common fault checks.
The popularity and development of wind turbines are extremely rapid. The effect and function of wind turbines are also huge. If we can master some common fault judgments when using wind turbines, we may reduce unnecessary losses when the wind turbine fails. Next, we will introduce the fault diagnosis of wind power generation in detail.
Compared with the grid-connected power generation system, the cost of the off-grid power generation system is higher than that of the grid-connected power generation system because it needs to be equipped with a battery as an energy storage device. The size of the power generation system generally needs to be smaller than that of the grid-connected system, and the power generation efficiency is low, but the off-grid power generation system exists independently from the national grid, which can save the cable lines connected to the power grid, so that the length of the cables used in the entire system is much less than grid-connected power generation system, so the off-grid power generation system can be installed faster and more conveniently on site.
A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The structure of the generator is generally composed of the nacelle, rotor blades, shaft center, high-speed shaft and its mechanical brake, generator, yaw device, electronic controller, hydraulic system, cooling element, tower, anemometer and wind vane, tail rudder. Wind turbines are generally composed of wind turbines, generators (including devices), regulators (tails), towers, speed-limiting safety mechanisms, and energy storage devices.
Wind turbine charge controller is an intelligent controller specially designed for wind power generation system. Making full use of wind energy resources to generate electricity, the equipment can not only efficiently convert the electrical energy generated by the wind turbine to charge the battery, but also provide powerful control functions.

A wind turbine first uses wind energy to generate electricity, and is a device that converts wind energy into mechanical energy and then into electrical energy. And wind energy, as a clean and renewable energy, is inexhaustible.
No matter what kind of tools, there will be a life limit. The service life of wind turbines is usually twenties years. But does this mean that we can use wind turbines without worrying about their maintenance? The answer is negative. Even if the lifespan of a wind turbine is twenties years, we still need to do some regular maintenance. Today we will introduce the basic maintenance of wind turbines.
Wind turbine operation and maintenance mainly refers to the regular maintenance and daily maintenance of wind turbines. Today we will talk about regular maintenance.
Wind turbine is an important equipment in the process of energy conversion. Shaft is a very important part of wind turbine. And the shaft wear of wind turbine is a common problem of this equipment. Once this problem occurs, the user needs to face a series of problems in disassembly, return to the factory or repair welding.
Each item has a different lifespan. How long the service life of wind turbines is, this is also a question that many people want to know. Generally speaking, the service life of wind turbines is more than 20 years. But if we can maintain the wind turbine, its service life can be extended.
Sea-land breeze is a diurnal local wind that occurs in offshore and coastal areas. Land and sea winds are caused by the temperature difference between land and sea during the alternation of day and night. That is, the temperature over the sea is lower than the land during the day and higher than the land at night. The temperature difference brings about the density and pressure difference of the near-surface atmosphere, and the pressure gradient force pushes the air flow from regions of high pressure (low temperature) to regions of low pressure (high temperature).
