“仙踪林company limited 19岁英文”中国西南地仙踪林company limited 19岁英文区首个特高压交流输电工程投运

  中新仙踪林company limited 19岁英文网重庆12月27日电 (记者 仙踪林company limited 19岁英文周毅)27日,中国西南地区首个特高压交流工程——国家电网川渝1000千伏特高压交流工程建成投运,可提高川渝电网跨省跨区互联互济能力,有效增强西南电网系统稳定性、运行可靠性和资源配置能力,有力提升成渝地区双仙踪林company limited 19岁英文城经济圈整体电力保障能力。

  川渝1000千伏特高压交流工程是国家“十四五”电力发展规划重点项目,工程总投资286.31亿元。该工程作为中国首个高海拔特高压交流工程,是继晋东南—南阳—荆门1000千伏特高压交流试验示范工程后具有里程碑意义的标志性工程。该工程途经四川甘孜州、雅安市、眉山市、乐山市、内江市、资阳市和重庆潼南区、铜梁区等8个地市(州、区),新建1000千伏线路1316公里。该工程在四川、重庆两地新建甘孜、天府南、成都东、铜梁4座1000千伏变电站,变电总容量2400万千伏安。

  该工程投运后,中国西南电网的主网架电压等级从500千伏提升到1000千伏,每年最大可从川西等地向四川、重庆负荷中心输送清洁电能350亿千瓦时,相当于近1000万户家庭1年的生活用电量,对保障今冬明春及未来西南地区电力安全可靠供应、增强川西地区电力送出能力、加快建设新型能源体系和发展新质生产力、推动高海拔特高压输电技术创新突破、带动上下游产业及服务地方经济社会高质量发展意义重大。

  随着成渝地区双城经济圈建设的不断推进,川渝两地用电需求高速增长,预计到2025年,四川、重庆最大用电负荷将达到约7500万千瓦、3100万千瓦,分别比2020年增长48.0%和38.0%。川渝特高压连接四川、重庆电源和负荷中心,实现了四川、重庆十余年的特高压交流联网构想,投运后将提升四川水电通道送出能力480万千瓦,提升川渝断面输电能力最大400万千瓦,提升重庆市电力保障水平,推动用能结构优化。(完)
