西藏华电琼结风电基地二期项目是西藏唯一入选国家能源局新型电力系统建设能力提升试点(第一批)项目,坐落于海拔4800米至5350米的高山地带,总装机150MW,旨在推动高寒高海拔新能源开发。
中新网拉萨10月10日电(白玛玉珍)10月8日,由中国建筑第二工程局有限公司承建的西藏华电琼结风电基地二期项目完成全部风机吊装,这座全球罕见的超高海拔山地风电项目正式转入电气安装调试阶段,向着按期全容量并网发电迈出关键一步。

该项目坐落于西藏山南市琼结县,风机散布在海拔4800米至5350米的高山地带,总装机150MW,装配24台6.25MW风电机组,配套建设集电线路、铁塔与220kV升压站,是西藏唯一入选国家能源局新型电力系统建设能力提升试点(第一批)项目,承担高寒高海拔新能源开发使命。
“这里空气含氧量仅平原50%—60%,昼夜温差超20℃,阵风说来就来,不仅考验人的身体,大型起重设备也容易动力衰减,每一台风机吊装都是一场硬仗。”中国建筑第二工程局有限公司项目经理张海亮介绍,单节塔筒最重101.9吨,叶片长达97.3米,轮毂中心高度达113米,有效作业时间十分碎片化。

针对高原工况痛点,项目落实大型机械“一机一策”维保,更换高寒专用油料,改造动力与液压系统;在半径15公里布设多点智能气象监测站,实时捕捉风速风向,抢抓转瞬即逝的安全施工窗口;现场采用模块化、单叶片吊装工艺,依靠引导销精准对位,完成数百颗高强度螺栓紧固核验,守住高空作业质量安全关口。
大件运输同样险象环生。场内盘山路超50公里,海拔落差超1500米,临崖急弯密布。中国建筑第二工程局有限公司建设团队全域踏勘测绘,制定分级转运方案,落实路基加固、分段错峰、临崖单侧通行等举措,全程监控构件形变,将庞大风电构件安全送抵山脊机位。
在工程建设中,项目坚持守护高原脆弱生态。前期依托无人机比选机位,避让高山草甸核心区;严控施工边界,建筑垃圾随产随清,优先复用既有道路;对临时占地及时开展植被修复;常态化开展野生动物巡查,引入第三方环保监理全过程监督,做到开发与保护并行。
据悉,项目投产后,预计年发电量3.94亿千瓦时,可满足约17.5万户家庭一年用电,每年减排二氧化碳约33万吨,源源不断输出雪域高原的清洁风能,实现经济、社会、生态效益协同增益。(完)

US President Trump announced the temporary lifting of sanctions on Russian fuel to curb oil prices. The Australian government stated on the 10th that it would not follow suit. Climate Change and Energy Minister Bowen emphasized that Australia does not need Russian fuel and is not willing to allow Putin to profit from the war in the Middle East.

Taiwan's China Petroleum Corporation announced that starting from next Monday (12th), gasoline and diesel prices will remain unchanged. Although international oil prices have risen due to the situation in the Middle East and the impact of hurricanes in the United States, in order to stabilize domestic prices and take care of people's livelihood, CNPC continues to implement the stabilization mechanism and expand absorption.

Australia will keep its ban on Russian fuel imports to prevent revenue for Moscow's war effort, citing sufficient domestic petrol and diesel reserves. Energy Minister Chris Bowen stated the country does not need or want Russian fuel, rejecting any benefit to Vladimir Putin from the war. Australia has 43 days of petrol and 31 days of diesel stockpiles.

Hurricane Isaias moved to the northern Gulf of Mexico in the United States, and oil companies shut down more than 70% of crude oil production. Brent crude oil closed up 0.42% at $104.72/barrel on Friday, and WTI crude oil rose 0.39% to $91.85/barrel. Trump said that negotiations with Iran were fruitful and was considering suspending federal gasoline taxes. China planned to resume refined oil exports after the National Day Golden Week. The threat to shipping in the Strait of Hormuz increased, adding to market volatility.
During the National Day holiday, State Grid Zhejiang Electric Power organized a market-oriented virtual power plant to fill the valley, with the maximum response load reaching 3.5952 million kilowatts, setting a new domestic record. Among them, the maximum response of user-side energy storage was 1.0641 million kilowatts, which also set a new domestic high, effectively promoting the on-site consumption of excess photovoltaic green power at noon.

Taipower's independent director Liao Huizhu pointed out that Taipower's cumulative losses may exceed 400 billion yuan, and advocated that a 71.1 billion yuan subsidy is more in line with the overall interests of the country. If the Legislative Yuan is unwilling to provide subsidies, the chance of an increase in electricity prices in December will greatly increase. She emphasized that Taipower has evaluated the possibility of restarting nuclear power, and called on Blue and White legislators not to insist on their own opinions in order to maintain the competitiveness of Taiwan's AI supply chain.
