#14億人用電自由如何實現# 從向資源要電，到向水流要電，如今已經向天要電。帶大家來探勘中國空中發電站！

這是我國研發的全球首台適用於城市環境的兆瓦級S2000浮空風力發電系統。

本系統由輕質浮空囊體、高效率涵道風機、智慧繫纜與地面控制站所組成。囊體內充滿氦氣，14000立方米氦氣可產生約14噸浮力，而係統總重約11噸，依靠浮力就可以「飛」起來。主氣囊內還設有兩個自動調節的空氣囊，可隨溫度變化維持內部壓力平衡。

與傳統風力發電類似，S2000浮空風力發電系統同樣依靠風推動葉片旋轉發電，差別在於它的發電設備不在地面，而在空中。

高空風力資源更豐富、風速更高、穩定性更強，發電效率也隨之提升。風經過此系統涵道結構後會加速，帶動發電機運轉，電能經由纜繩輸送至地面，經變流即可併網，滿發狀態下，每小時可發電1000度。

除了發電，該系統還可搭載通訊基地台、環境監測等設備，成為低空經濟的多功能平台。由於發電主體懸在空中，對地面影響小，適合在城市負載區就近部署，減少輸電損耗。在應急救災等場景中，也可快速部署提供電力支援。 #一分鐘影片創作季##科技##熱搜多元內容創作計畫# http://t.cn/AXqtDiok

   The worlds first megawatt-class high-altitude wind power system designed for urban deployment — the S2000 Stratosphere Airborne Wind Energy System (SAWES) — successfully completed a test flight in Yibin, Southwest Chinas Sichuan Province, on Monday. The achievement marks a key breakthrough as Chinas high-altitude wind energy technology advances from experimental validation toward engineering-scale application.
   
   From an environmental perspective, SAWES offers clear advantages, including a simpler structure, lower land requirements, and reduced environmental impact compared with conventional wind farms, according to experts. 
   
   The S2000 SAWES is an integrated airborne wind energy system that incorporates an airship platform and wind turbines into a single unit, and the whole system is 60 meters long, 40 meters wide and 40 meters high. 
   
   After an ascent of approximately 30 minutes, the S2000 reached an altitude of 2,000 meters during the test flight and generated 385 kilowatt-hours of electricity. It also successfully completed grid-connected power generation, becoming the worlds first high-altitude wind power device to be formally connected to the power grid.
   
   Dun Tianrui, CEO and chief designer of the systems main developer, Beijing-based start-up Sawes Energy Technology, told the Global Times on the sidelines of the test flight that the S2000 model can be deployed at altitudes of up to 2,000 meters, with a single-unit power output of about 3 megawatts. 
   
   "At its current output level, one hour of operation can generate enough electricity to fully charge approximately 30 top-spec electric vehicles from zero to full," he said.
   
   Compared with the S1500 model previously tested in Hami, Northwest Chinas Xinjiang Uygur Autonomous Region, from September 19 to 23, 2025, the S2000 features greater payload capacity and a fully upgraded weather-resistance design. These enhancements enable the system to operate not only in remote environments such as deserts and the Gobi, but also within urban settings, the company told the Global Times. 
   
   The entire S2000 SAWES can be transported in containers, and it takes only eight hours from site preparation in Yibin to full inflation, said Dun, noting that with local gas supply, the entire process can be reduced to four to five hours.
   
   The system combines mature wind power technology with an airborne platform and is deployed at high altitudes, where stronger winds offer greater power generation potential, Wang Yanan, editor-in-chief of Aerospace Knowledge magazine, told the Global Times on Monday, adding that its airborne design allows flexible deployment and retrieval, making it especially suitable for sparsely populated areas where large-scale infrastructure is difficult to build.
   
   According the National Energy Administration, as of the end of November 2025, Chinas total installed power generation capacity reached 3.79 billion kilowatts, up 17.1 percent year-on-year. Of this, installed wind power capacity reached 600 million kilowatts, up 22.4 percent year-on-year.
   
   Wang noted that the key to SAWES commercialization lies in whether the costs of manufacturing, deploying, retrieving, and transmitting electricity from the airborne system can be covered - or even exceeded - by the power it generates.
