1881年，世界第一座水电站在美国尼亚加拉大瀑布建成，它的设计容量达到14.7万千瓦时，是当时中国总发电量的3.2倍。可以想象，那个时候，整个中国的 电力供应，竟然被美国单个水电站远远甩在了后面。这一历史情节，触目惊心，令人深刻反思。 然而，时光荏苒，100多年后的今天，回望过去，中国早已凭借100%的电力覆盖率，为世界上最多的人口带来了光明。不仅是民用电力，中国的庞大工厂 群、如雨后春笋般涌现的军用装备、飞速发展的高铁和即将腾飞的国产大飞机……这一切的成就背后，都离不开一个稳健发展的电力系统的支撑。 中国电力的奇迹飞跃，背后是独具中国特色的发展模式。事实上，中国在电力发展的起步上，几乎和西方有着7年的时间差，然而，除了这个时间差，当时 中国比起西方的巨大差距，更加深刻的痛点是缺乏体制保障。19世纪末期，中国仍在清朝的统治下，国家腐败无力，内忧外患不断，半殖民地半封建的社会 结构让电力建设几乎无法依赖政府支持。那时，中国只能通过从西方殖民者带进来的先进技术，依靠民间力量发展电力。 新中国成立后，电力建设逐步从借鉴苏联到实现自主化，成为了国家工业化进程中的基础。以电力为支撑的工业建设，成为了国家发展的一项重要方 ...

原创 戎评说策 戎评 这两天本来想休息的，结果写习惯了，不写就觉得浑身不自在，今天我们聊点有意思的。 不知道从什么时候起，每当春节来临，中国就化作了一片流光溢彩的海洋。 东方明珠、西安不夜城、郑州CBD和全国各地的大街小巷，上千万盏彩灯彻夜通明。写字楼上的灯光秀、街头的花灯、商圈夜景组成了一幅幅震撼画 卷。不少外国博主在镜头前惊叹："让整座城市从黄昏亮到黎明，如此大规模不间断的电力供应，放眼全球都极为罕见！" 是的，有人已经意识到了。中国以一己之力，不但保障了全国14亿人的生活用电，还供应着上千万家企业的工业生产，19.4亿亩耕地的农业用电。即便 在这种压力下，我们的电还用不完，2025年还出口了230亿度，赚了126亿元人民币。这种强大的电力保障和发电供电能力，别说美国了，整个西方加 起来都自叹不如、望洋兴叹。 戎评这话不是开玩笑的，根据中国的官方数据，2025年中国的发电量突破10万亿度，占全球的三分之一左右，而美国为4.6万亿度、印度2万亿度、日本 1万亿度。也就是说，中国的发电量，比美、日、印、巴西和俄罗斯等国加起来的总和，还要多。 这么多电是从哪来的？ 年龄稍大的朋友会有印象，20多年前，我们的电根 ...

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 ...
