【砥砺奋进的五年·重大工程】中国特高压 创新引领能源革命

2017-06-25 18:02:18   央视网

央视网消息:特高压是目前世界上最先进的输电技术,目前世界上只有我国全面掌握这项技术,并开始了大规模工程应用。这五年,从运行3条到投运14条特高压输电大通道,输送数以亿计的清洁电能,中国特高压正在引领我国加速能源革命。

2383公里,世界电能传输最远距离再一次被刷新,甘肃酒泉送湖南特高压工程正式投运,它将甘肃的风能、太阳能发出的清洁电能,直接送往湖南。

邓庆红

国网湖南省电力公司建设部副主任邓庆红:有了这条特高压,每年可以给湖南送电400亿度,可以满足湖南目前四分之一的用电需求。而通过华中电网,这些电还可以惠及华中其它省市。

因为有了更多的清洁电能,湖南开始大规模推进工业领域煤改电,郴州的这家铸造工业园,正在将燃煤锅炉全部改成电锅炉,改造完成后,仅这一个园区,一年就可以少烧5.6万吨煤,而整个湖南今年更是可以少烧159万吨煤。

黄其励

中国工程院院士黄其励:世界上输送能力最大的,输送距离也是最远的,这样一个特高压直流输电工程,正好对世界能量输送,清洁能源输送有非常大的实践意义,中国带了个头。

特高压是目前世界上最先进的输电技术,目前世界上只有我国全面掌握这项技术,并开始了大规模工程应用。这五年,我国从运行3条到投运14条,再到新建9条特高压大通道,电压等级、输送容量、输送距离不断刷新世界纪录,基本形成了西电东送,北电南供的特高压输电网络。

眼下,我国又开始着手研究实践,更好消纳、传输风电、光伏等不稳定电能的柔性特高压技术,就在几天前,我国自主研发出了世界首个特高压柔性直流换流阀。

李岩

南网科研院直流输电技术研究所所长李岩:换流阀是直流输电的心脏。有了这个换流阀,就可以打造新一代的特高压直流输电系统。为大容量、远距离清洁能源的接入,这一世界性难题提供有效解决方案。

李立浧

中国工程院院士李立浧:我们的特高压输电的技术理论,机理,工程建设,设备制造能力方面都创造了很多记录。从中国创造到中国引领,占领了世界电网技术的制高点。

这五年,通过一条条特高压输电大通道,中东部16个省份近9亿人,用上了来自西部的清洁能源。每年东中部因此少烧了9500万吨煤,相当于四川省一年的煤炭消耗量。

这五年,无论是特高压技术、标准还是重大装备,都实现了完全自主,中国特高压标准,已经被确定为国际标准向全世界推广。

这五年,中国特高压成功实现“走出去”。巴西美丽山水电站特高压输电工程由我国企业总承包,特高压已经成为彰显中国自主创新的靓丽名片。
