美苏日全折戟,中国却做到了!想学这一招?全球标准都由中国定!
Sou Hu Cai Jing· 2026-02-18 15:14
在这样的困境下,很多人都会问,得州发生了停电,难道不能从其他州调电过去支援吗?毕竟咱们中国 在遇到困难时,总是有难八方支援,电网相互连接,大家都能帮上一把。可惜,美国的电网体系并不像 咱们想的那样。美国本土的电网是三足鼎立的:东部电网、西部电网,还有一个就是特立独行的得州电 网。而这三个电网几乎完全没有互联互通,彼此之间就像是三个独立的王国,即便东部和西部电力充 足,也无能为力,根本无法互相支援。 那美国人是不是傻,竟然不知道把电网连起来呢?当然不是!其实,他们早就想过这一点,也做了不少 努力,但是技术实力始终限制了他们的能力。电力输送的最大难题就是损耗。随着输电距离的增加,电 力的损耗也会迅速增加。目前国际上使用的500千伏超高压输电,最经济的传输距离大概在600到800公 里左右。可得州离东西部的主要电源点动辄超过1500公里,这样的距离,电力如果强行送过去,发出的 电是100度,送到目的地可能就只剩下几度了。如此一来,根本没有人愿意做这种亏本买卖。 大家好,欢迎来到老闫侃时事!最近,美国能源部长在公开场合的一番话,真的是让人意外到掉下巴。 她居然直言不讳地表示,希望能向中国取取经,看看咱们在特高压输电技 ...
