Experts question wind power generation in tunnels

The idea of ​​“using wind energy from subway tunnels to generate electricity” has aroused the curiosity of many people and also caused some doubts. "Although from the perspective of efficient energy utilization, the wind power generated in the metro system can be used for development and utilization, the wind power generated is too small and it is difficult to achieve economies of scale, which has no economic value in "Zhou Tao, a new energy sector analyst at Great Wall Securities, believes that he has not heard of the practice of to use wind energy in the city to generate electricity around the world. Even if the metro company agrees to develop such a project, it will be difficult to attract investor interest.

Wang Mengshu, an academician of the Chinese Academy of Engineering, is also not optimistic about this project. He thinksthat the idea of ​​using wind energy in tunnels to generate electricity is simply impossible and technically unreliable. He explained that trains running on metro lines had time intervals. At present, Beijing's fastest Line 1 generally has an interval of more than 2 minutes. Therefore, even if a small wind turbine is installed in the tunnel, it cannot obtain sustainable and stable wind power.

As the two parallel metro tunnels are every 400 to 500 meters, they are connected by passages in the middle. In these two tunnels, the wind generated by the passage of the metro train will enter the other tunnel. Additionally, the trains in the two tunnels run in different directions, so the wind directions are also different. This makes it difficult for wind power equipment to operate continuously and stably.

In response to the doubts of experts,Zhong Yan said that in some actual tests they carried out, they did not find the problems caused by the wind direction in the tunnel mentioned by academician Wang Mengshu. In response to the questions raised by the experts, they also wished to communicate with relevant experts, including Academician Wang. For safety reasons, they considered designing the wind rotors mounted on both sides of the subway tunnel as thin cylindrical wind rotors.

Have you ever considered the principle of the wind tunnel for the production of electricity in tunnels? Subway operation requires excess air at the front to be pushed toward the rear of the car as quickly as possible. In this way, the locomotive can operate with minimal energy consumption. Adding windproof devices around the tunnel will definitely affect the speed and power consumption of the locomotive. Adding some wind powernes around the tunnel will increase the area upwind of the front of the locomotive. Increases wind resistance.
