When the last rays of the setting sun fall on the vast forest of wind turbines, the rows of towering fuselages are dyed golden red, making them even more sparkling. One of the magnificent generators stands tall like a white giant, and its 130-meter body is like a sword pointing straight into the sky, like a giant sculpture lying in the woods.
With the breeze blowing, the three fan blades rotate slowly, and although the speed seems slow, the steady and powerful rhythm reveals the power within. With each rotation, a huge amount of torque is transmitted to the internal machinery of the generator, driving the generator set to run efficiently.
Even in the afterglow of the setting sun, the generator continues to output electricity, delivering a steady stream of power to distant cities. The rotating fan sometimes blocks the light of the last rays of the sunset, and sometimes flashes a little dark red in the reflection of the setting sun, and the whole wind farm is like a never-ending energy city, full of vitality and vitality.
Looking back on 2021, the wind power industry in mainland China has developed rapidly like a galloping horse. The total installed capacity of wind power reached an astonishing 566.7 billion kWh, accounting for 6.99% of the country's total power generation.
This figure not only fully reflects the government's firm determination to develop clean energy, but also reflects the growing demand and enthusiasm of the general public for green electricity.
With the continuous acceleration of the pace of modern life, the types and quantities of various household appliances are also increasing day by day. Whether it's the slight sound of the air conditioner or the occasional hum of the TV, it speaks of people's insatiable thirst for electricity.
Due to the significant advantages of clean and environmental protection, renewable wind power generation has quickly won wide attention and warm welcome from the whole society.
The government and enterprises have invested heavily in building spectacular power generation bases on the land of the motherland. Researchers worked day and night to develop innovative technologies to improve the efficiency of power generation, workers braved the scorching sun and wind and rain, worked hard for months, and went all out to meet the deadline.
Looking to the future, this clean energy industry will undoubtedly have broader development prospects.
Let's focus once again on the generator that is running. In the afterglow of the setting sun, it seems to be just turning the blades leisurely, but in fact, there is a mysterious and magical energy conversion process hidden behind it.
First of all, the breathtaking thing is the giant three-bladed fan, which acts like a spinning blade sail that effortlessly absorbs the powerful energy released from the dancing air currents. When a strong wind blows over each delicate blade, it brings a steady propulsion that pushes the blades to rotate slowly.
This seemingly insignificant force, after accumulation and amplification over time, was able to drive the entire huge machine to rotate in an orderly manner!
Immediately afterwards, the rotational motion of the blades cleverly drives the power generation mechanism inside the generator set to rotate in an orderly manner through the precision mechanical connecting rod. In power generation mechanisms, countless precision coils are moving at incredible speeds, gradually converting mechanical kinetic energy into a constant and steady current.
At this point, you may be curious to ask: if the blades of this behemoth could spin faster, would it produce more power?
From a safety point of view, if the speed of the generator is too high, the blades will be subjected to enormous centrifugal forces. Once out of control, the blades weighing several tons or even the entire body can deviate or break badly at high speeds, and the consequences are unimaginable.
Master Zhang, a worker, fondly recalls that he had witnessed a serious accident caused by a generator running too fast. At that time, a generator with a blade diameter of more than 80 meters suddenly lost its balance in the frantic rotation, and the huge blade was instantly torn into two pieces, flying around like branches and leaves, and the scene was thrilling.
In the end, the disaster resulted in the tragic death of two people, the serious injury of six people, and the repair loss was as high as millions of yuan.
"What we are most afraid of in this industry is such an unexpected situation," Master Zhang said with emotion, "Therefore, everyone realized that the speed of the generator must be strictly controlled within the safety range, which is not only related to the equipment itself, but also directly affects the life safety of workers and surrounding residents." ”
Despite its slower speed, the generator is able to provide a lot of power thanks to the design concept of extra-large fan blades. Just like the great windmills of ancient times, the larger the blade area, the more wind energy it can capture and utilize.
Standing on a platform about 200 meters away from the generator, a large number of technicians are nervously and attentively monitoring the important data. "Today's wind speed is stable at around 10 meters per second, and now is the best time to start this large 1.5 MW wind turbine!" said Liu Gong, the duty manager, excitedly.
As he finished speaking, the three-bladed giant fan began to rotate slowly, and each blade that was more than 70 meters long and weighed 6 tons was like the world's largest windmill blade, cutting the surrounding air with incomparably powerful force. "Look, the current power generation has exceeded the 1000 kWh mark!" Liu Gong proudly pointed to the meter and announced excitedly.
Engineers have calculated that the generator can generate up to 1,500 kWh of electricity per hour at an ideal wind speed of 10 meters per second, which is enough to meet the daily electricity needs of a medium-sized community for nearly 50 days. It is no exaggeration to say that although its rotation speed may seem slow, behind those three huge blades, there is an amazing potential for energy.
With the continuous growth of global energy demand and the increasing popularity of environmental awareness, wind power as a clean energy will undoubtedly have a broader development space in the future. "You see, just in 2021, the mainland's total installed wind power capacity has successfully reached 566.7 billion kWh, accounting for 6.99% of the country's total power generation. And this number is still rising year by year!" Liu Gong pointed to the statistical chart on the wall, confidently showing us, "As the country and enterprises pay more and more attention to the development of clean energy, the future prospects of the wind power industry will be more dazzling."
He paints a magnificent picture of the future with passion: "By then, large wind turbines such as the V164 produced by our company will be scattered all over the country, including super generators with a power of up to 8,000 kilowatts and 'green giants' with a diameter of more than 200 meters." These behemoths will be as indestructible as the steel giants of the forest, providing a steady stream of clean electricity for generations to come.
