With the rapid development of science and technology, the exploration and utilization of renewable energy are also constantly upgrading. In this context, an exciting news came from China's science and technology community: on January 7, 2024, the "Jixi High-altitude Wind Power Generation New Technology Demonstration Project" jointly built by China Energy Construction China Power Engineering and Zhonglu Co., Ltd. successfully generated electricity, marking the official launch of China's first grid-connected megawatt high-altitude wind power generation demonstration project. This is not only a major breakthrough in high-altitude wind power generation technology, but also an important milestone in the history of China's new energy development.
High-altitude wind power generation, as the name suggests, is an innovative technology that uses wind resources in the sky to generate electricity. Unlike traditional wind power, high-altitude wind power raises wind capture devices to an altitude of 500 to 10,000 meters, taking advantage of the region's high winds and stable wind direction. In this altitude range, the wind is stronger and more stable, so upper-air wind power generation has a higher energy density and a more stable power generation output.
The Jixi high-altitude wind power generation technology demonstration project, which successfully generated power this time, adopts a unique umbrella-ladder combined land-based high-altitude wind power generation technology. This technique works somewhat like "kite flying" in our daily lives: a set of "umbrella groups" containing a work umbrella and a balance umbrella are sent into the air through the initial lift provided by a helium balloon; As the parachute captures a strong wind force in the air, it creates a huge pull on the main cable; This pull is then converted into mechanical energy by the generator set on the ground and ultimately into clean, renewable electricity.
In this process, the role of ground equipment is also indispensable. Ground equipment such as cable storage and rope winch, tensioning device, and main winch together form a sophisticated operating system, which ensures the stable movement of the "umbrella group" at high altitude and the continuous output of electric energy. Among them, the winch system, as one of the core equipment on the ground, is breathtaking in its fast running speed and high control accuracy.
It is worth mentioning that high-altitude wind power generation not only has efficient and stable power generation performance, but also performs well in terms of environmental protection and sustainability. Because high-altitude wind power does not require the same amount of land resources as traditional wind power, and does not have a significant impact on ecological environments such as bird migration, it is considered a greener and more sustainable way to generate electricity.
Of course, the birth and development of any new technology is inseparable from the hard work and continuous innovation of scientific researchers. Behind the Jixi high-altitude wind power generation new technology demonstration project is the joint efforts of many enterprises and scientific research institutions such as China Energy Construction China Power Engineering and Zhonglu Co., Ltd. They have made great efforts in the research and development, equipment manufacturing, and project construction of high-altitude wind power generation technology, and finally achieved this remarkable result.
So, what does the future hold for high-altitude wind power technology? It is certain that with the continuous optimization of the global energy structure and the growing demand for renewable energy, high-altitude wind power generation technology will usher in a broader space for development. We have reason to believe that in the near future, high-altitude wind power generation will become an important force in the field of new energy, and make greater contributions to promoting global energy transition and sustainable development.
To sum up, the successful power generation of the Jixi high-altitude wind power generation new technology demonstration project is not only a major breakthrough in the development of new energy technology in China, but also a new chapter in the history of global renewable energy development. Let us hope that high-altitude wind power generation technology can create more miracles in the future and inject new vitality into the sustainable development of human society.
