Construction of China's first commercial spacecraft launch site started Wednesday in Wenchang City, south China's island province of Hainan. As a major project of the Hainan free trade port construction, the Hainan commercial spacecraft launch site is committed to becoming world-class, market-oriented, and further improving the launching capability of China's commercial carrier rockets.Photo taken on July 6, 2022 shows the construction site of Hainan commercial spacecraft launch site in Wenchang City, south China's Hainan Province.

However, the new commercial launch center will be aimed at meeting China’s burgeoning commercial space industry in the longer term.,"The existing government-run launch centers are well developed but they are too busy to handle the increasing demands from the commercial space sector and it is not uncommon that even a government-assigned mission would have to wait for arrangement at those sites," Hu Shengyun, a senior rocket designer at China Aerospace Science and Industry Corp, told China Daily.,He added that the state-operated launch sites were not designed for the volume of traffic that the commercial site will have to handle, so it is better if they don’t have to worry about it.,© Guo Cheng/XinhuaAerial photo taken on July 6, 2022 shows the construction site of Hainan commercial spacecraft launch site in Wenchang City, south China's Hainan Province.

It will also include facilities for rocket assembly and testing. Its location so close to Earth’s equator will give rockets a major speed boost, saving on fuel.,Ningbo, in the eastern Zhejiang Province, is also expected to build a similarly impressive commercial launch facility, as is Haiyan in Shandong Province.,However, the private space industry sector, which is still small in China, reportedly has doubts about the new facility.,“I don’t think those pads are going to be cheap,” a source who works for a commercial launch start-up based in Beijing told the South China Morning Post. “I’m not sure how many commercial launches will be planned each year, but that is likely to be a small number, so each launch is going to be really expensive.”。该项目总装机容量800兆瓦，配套建成亚洲首座海上柔性直流换流站，2021年实现全容量并网投产。柔性直流输电技术如同海上风电外送的智能输电通道，适配深远海大容量电力输送场景，能够有效平抑风电出力波动，保障海上清洁能源平稳、可靠并入陆上电网。自并网以来，项目持续保持安全平稳运行状态，长期运行指标保持良好水平。　　作为行业开创性工程，该项目建设运营阶段并无成熟工程经验可供直接参照。建设与运维团队直面深远海复杂海洋环境，持续开展技术攻关，着力破解海上柔性直流系统稳定调控、长距离海底电缆运维、变负荷工况协同控制等一系列关键难题。相比传统交流输电模式，柔性直流送出方案有效控制远距离输电损耗，在提升输电效率、增强新能源并网适配性等方面展现突出优势。　　海上风电正持续向离岸更远、水深更深的海域推进，远距离电能送出已经成为制约深远海风能开发的关键环节。传统交流输电方案随着输送距离增加，技术与经济短板逐步凸显，柔性直流输电被业内视作破解深远海风电外送难题的重要技术路径。
