中新网成都9月22日电(刘忠俊 高珩瑞 谢春艳)国网四川省电力公司22日发布消息,随着最后一相导线走板抵达预定位置,四川攀西特高压交流工程首个区段放线作业顺利完成,并安全跨越±800千伏金上至湖北直流输电线路以及2条500千伏输电线路,为工程后续推进奠定基础。
攀西特高压交流工程于2026年3月底开工,新建攀西、川南2座1000千伏变电站,线路途经凉山、宜宾、乐山三市(州)。此次完成放线作业的区段新建铁塔22基,线路全长约7.3公里。该区段跨越密集,高塔、重型铁塔多,单基铁塔最大重量达518.5吨,最大塔高160.8米,施工任务重、建设工期紧。“特高压线路建设通常分段推进,且跨越施工必须在既有线路不带电的状态下开展。”攀西特高压交流工程线路工程东段业主项目部执行副经理杨译介绍,当前正值电网秋季检修窗口期,工程所跨线路均不带电。
为确保工程顺利推进,国网四川省电力公司提前谋划、挂图作战。施工团队推广机械化组塔工艺,针对120米以上超高铁塔,采用“吊车+摇臂抱杆”组合施工模式,提升高塔组立稳定性与施工效率。
放线环节,现场同步展开4个架线区段、投入40台配套牵张设备,将传统的串行施工改为并行同步施工,大幅压缩整体施工时长。“我们将11标段中跨越密集的线路列为‘提前架线区段’,‘拎出来’提前施工,在有限工期内完成最关键的跨越。”杨译说。
攀西特高压交流工程预计2028年建成,年最大输送电量约182亿千瓦时,相当于替代标煤约588万吨、减排二氧化碳约1446万吨。
工程建成后,攀西清洁能源向成都平原及川南负荷中心的输送能力将增强。届时,甘孜、阿坝、攀西三大清洁能源基地与成都平原、川南、川北三大负荷中心之间将形成“三送三受”的电网格局,四川主网架的安全稳定水平和供电承载能力也将进一步提升。

The Greater Bay Area Hydrogen Energy Comprehensive Application Pilot City Group held a work deployment meeting in Guangzhou. The urban agglomeration consists of 11 cities. It plans to promote 16,000 hydrogen fuel cell vehicles, build 100 hydrogen refueling stations, and build four cross-provincial hydrogen energy transportation corridors during the four-year pilot period to promote the large-scale application of the hydrogen energy industry.

Saudi Arabia's East-West oil pipeline has restarted operations after being attacked by drones, and crude oil export operations at Yanbu Port on the Red Sea coast are expected to gradually resume on the 22nd. The pipeline is currently moving at lower rates and full recovery may take weeks.

The Xinjiang Production and Construction Corps promotes the "medicine-light complementation" model on the southern edge of the Gurbantunggut Desert, using the space under photovoltaic panels to plant mugwort and other traditional Chinese medicines. This model not only increases the land output value, but also improves the ecological environment through vegetation and sand fixation, achieving a deep integration of new energy and specialty agriculture.
During the "15th Five-Year Plan" period, Hainan Yangpu Economic Development Zone will focus on building a new energy system, industrial green transformation and institutional integration innovation. By introducing nuclear power, building a near-zero carbon park and aligning with international carbon management rules, it will create a national leading green and low-carbon industry demonstration park.

The Nalingrad River Water Conservancy Project in Haixi Prefecture, Qinghai Province has entered the unit commissioning stage before putting into operation for power generation. As a major national water conservancy project, after completion, the project will solve the drought and water shortage in the Qaidam Basin, ensure industrial water supply, and form an integrated clean energy system of "hydropower + wind and solar storage".
Thailand’s National Energy Policy Committee approved the expansion of the public solar power generation plan on the 18th, raising the cumulative power purchase target to 10,000 megawatts. The purchase price of residents' surplus electricity is set at 2.20 baht per kilowatt hour, and the period is extended to 20 years, aiming to promote the transformation of the energy structure and reduce dependence on petrochemical energy.
