China's SL5000 giant wind turbine uses ruby ​​as its probe. How much value can it create?

Now countries around the world are paying more and more attention to environmental protection, and support for the development of new energy is increasing. China is also not weak. China has succeeded in the past few years. One of the most powerful offshore wind turbines in the world has been developed. It is the Chinese SL5000 giant wind turbine. The technical difficulty of this China East China Sea power generation giant is quite high. In addition, China has only three countries in the world. , Even the probe for testing it is directly made of sky-high ruby, so how much value can it create for China? This giant wind turbine has a generating power of more than 10 megawatts. The construction of a dozen of them is equivalent to a medium thermal power station. The total installed capacity of wind power under planning in China is more than 60,000 megawatts, which is equivalent to Three Gorges. The dam is more than three times larger, and they will become the main force of China's energy supply in the future.

Wind power is a new energy that all countries in the world attach great importance to, especially China, which has a large area of ​​undeveloped land and seafront, if it can If enough wind turbines are built, the energy they output is sufficient to meet the power demand of the entire China. The development direction of wind turbines is to have a larger single generating power. At present, the single generating power of advanced wind turbines in the world has reached 10%. At the megawatt level, China has also developed a domestically-made SL5000 giant wind turbine. Its wind power generation has reached 10 megawatts, the blade length is nearly 100 meters, and the sweeping area is equivalent to the size of several football fields. The technology is very advanced. .

In order to achieve such high performance, China has broken through a lot of technical difficulties. The manufacturing process of such a huge generator is quite demanding.The surface accuracy required for a blade with a size of nearly one hundred meters is within 0.001 mm, which is equivalent to only one bump with a large sand grain is allowed on a basketball court. For this reason, even the precision probes for inspecting the surface quality of the blades are expensive. Made of ruby, so that such tiny bumps can be detected, and the strength of the composite material needed to make such a giant blade is also increased. It took China more than a year to develop it successfully.

But the effort to develop such a super wind turbine is worthwhile for China. The power generation of 10 MW is equivalent to the power of a small thermal power station or hydropower station, but its construction cost is far Lower than traditional power stations, and with smaller footprint and less pollution, China is planning to build more wind turbines. According to statistics, China’s offshore wind power generation is now equivalent to 23% of the world’s total offshore wind power generation. Surpassed the United States to become the world's number one.

and China is also planning to further increase domestic wind power generation capacity. By 2025, China’s wind power generation capacity will increase to more than 60,000 megawatts , More than three times that of the Three Gorges Dam, equivalent to 10% of the total power generation in China, equivalent to saving tens of millions of tons of coal consumption, and China will also develop more powerful wind turbines. It is said that China is now The research and development of 12 MW and 15 MW and wind turbines have been initiated, and they will become the main force in China's wind power generation in the future.

For a country as large as China, the development of new energy is the only way to maintain the country’s sustainable development. Fortunately, China now has a strong enough comprehensive national strength to invest heavily in research and development of wind turbines with more advanced performance. And as China's wind power and other new energy power generation accounts for the increase in the proportion of total power generation, China will also realize the great promise of carbon neutral sooner.
