China's first high-altitude wind energy project successfully generates electricity: "flying a kite" at an altitude of 3,000 meters to generate electricity

The Jixi high-altitude wind power generation new technology demonstration project in Anhui Province, which China Energy Construction Group participated in the investment, construction and operation, successfully generated electricity.It has become my country’s first megawatt-level high-altitude wind energy power generation demonstration project that can be connected to the grid.The project has a total installed capacity of 2x2.4 MW and can use high-altitude wind energy from 500 meters to 3,000 meters to generate electricity. It is the first engineering practice of high-altitude wind power generation technology in my country.

According to reports, high-altitude wind energy has the advantages of abundant reserves, high wind speed, and stable wind direction. As the distance from the ground increases and ground friction decreases, high-altitude wind speed will gradually increase, and wind energy is proportional to the cube of wind speed.

Relevant research shows thatThe average wind energy density at an altitude of 6,000 meters in my country is more than 20 times the wind energy density on the surface. The wind energy contained in the high altitude exceeds the current total energy demand of human society by more than 100 times.

In addition, high-altitude wind power generation can be divided into two technical forms: air-based wind power and land-based wind power generation.

Space-based high-altitude wind power generation, the generator is suspended in the air, flies in the air, and generates electricity in the air; land-based high-altitude wind power generation, places the generator on the ground, flies in the air, and generates electricity on the ground.

my country's first megawatt-level high-altitude wind energy power generation project that can be connected to the grid uses umbrella-ladder combination land-based high-altitude wind energy power generation technology.

After the parachute group reaches a certain height by providing initial lift through a helium balloon, it opens the power parachute to collect and capture wind energy at an altitude of more than 500 meters.

The "power parachute" aircraft is tied to a cable and flies to a high altitude like a kite. The aircraft drives the cable to reciprocate under the action of the wind, and the ground generator turntable rotates to generate electrical energy.
