China's high-altitude wind power technology has achieved a major breakthrough, as the domestically developed S4000 Stratosphere Airborne Wind Energy System (SAWES) recently completed a test at a base in Northwest China, CCTV News reported on Saturday.
An upgraded version of the earlier S2000 SAWES, and the successful completion of its full-process flight validation marks the transition of China's stratospheric high-altitude wind power technology from the iterative development phase toward the engineering deployment phase, according to the report.
The test covered the entire process of ascent, station‑keeping, power generation testing, and smooth recovery, with all indicators meeting the required standards, fully verifying the system's reliability in complex and extreme high‑altitude environments, the report said. 
As an upgrade from the S2000 model, the S4000 adopts a new configuration with significantly improved overall performance. Its maximum operational altitude reaches 4,000 meters, making it suitable for deployment in the vast majority of regions across China. 
It can directly adapt to mainstream grid power supply requirements and has a design service life of up to 20 years.
Unlike conventional low-altitude wind turbines, which are often referred to as "windmills," the system employs a flying device.

。      当前，高温、暴雨等极端天气多发，用电负荷大幅攀升，工贸企业火灾、触电、中毒窒息风险显著上升。部分企业为节能降耗加大夜间生产强度，人员疲劳、夜间视野受限等因素叠加，机械伤害、高处坠落事故进入易发期。为有效防范化解工贸企业8月份突出安全风险，应急管理部向工贸企业发出安全生产工作提示，严防六类生产安全事故，并加强“厂中厂”“园中园”安全治理。  一是严防有限空间作业中毒窒息事故。要严格落实有限空间作业审批制度，作业前必须对有限空间气体浓度进行检测，作业现场必须配备安全防护和应急救援装备，设置专职监护人员，严防有限空间作业事故发生。

B |   二是严防高温熔融金属遇水喷爆事故。

C | 要定期检修熔炼炉等炉体水冷装置，避免冷却水泄漏进入炉内接触高温熔融。

D |   三是严防触电事故。

E | 要对电气线路、开关、配电箱、用电设备等开展全面排查，重点整治线路老化、绝缘破损、超负荷运行等隐患。  四是严防机械伤害事故。要严格执行作业前安全确认，落实岗位责任制和岗位操作规程，加强光栅、急停、防护罩等安全防护装置排查整治。  五是严防高处坠落事故。

F | 要严格落实高处作业审批制度，强化作业人员安全教育培训，规范佩戴安全帽、安全带等劳动防护用品。  六是严防危险化学品燃爆事故。

G | 涉及危化品储存、使用的工贸企业要严格落实降温、通风、远离火种等措施，严控高温环境下危化品泄漏、燃爆风险。  同时，各地区要加强工业“厂中厂”“园中园”安全治理，进一步摸清风险底数，压实出租方承租方安全管理责任，督促出租方严格落实统一协调管理责任、承租方严格落实安全主体责任，严禁堵塞疏散通道、非法违规生产经营、违法违规施工改造，严格动火作业安全管理，坚决防范火灾、爆炸、坍塌等事故发生。
