Brazilian here

Brazil has 90% of Electric Energy from Clean/Renewable most because the National Grid.

Because our country is huge and ALWAYS is raining somewhere, so the National Grid guarantee that the Energy will always be available Nationwide, no matter the place is being generated.

With the MASSIVE new investments in Wind and Solar, even in extremely drought Years, the System will be secured without the need to use of coal to fulfill the demand, and we are capable to export Energy from Colombia in the north to Argentina in the south.

巴西90%的电力来自清洁/可再生能源，这主要归功于国家电网。

因为我们的国家很大，总有某个地方在下雨，所以国家电网保证全国范围内的能源总是可用的，无论是在哪里发电。

随着对风能和太阳能的大规模新投资，即使在极端干旱的年份，该系统也不需要使用煤炭来满足需求，我们有能力从北部的哥伦比亚向南部的阿根廷出口能源。

China had the most UHVDC, the most high-speed railway lines, the most EVs, the most 5G base stations in the world. Seems China is just ahead of everybody!

中国拥有世界上最多的特高压直流输电、最多的高速铁路线、最多的电动汽车、最多的5G基站。看来中国领先所有人!

Just because China has central planning doesn't mean it doesn't send officials to discuss and consult with affected people what the purpose, impact, and compensation will be.  My dad got a free flat in the city when they tore down his village home for development.  

仅仅因为中国实行中央计划并不意味着它不会派人与受影响的人讨论和协商补偿。当他们为了建设而拆除我父亲在村里的房子时，在城里补偿了一套免费的公寓。

UHVDC is way more economically efficient than distributed small grid and energy storage for China. because China have 5time zones geographically.

对中国来说，特高压直流输电比分布式小型电网和储能更经济高效。因为中国在地理上有五个时区。

In the US we don't just not have UHVDC, we have barely any HVDC. And, unlike Australia, we have our renewable resources located far from our population centers. The problem is the way we manage our grid makes it nearly impossible to build tranmission lines that cross regions.

在美国，我们不仅没有特高压直流，我们几乎没有高压直流。而且，与澳大利亚不同，我们的可再生资源位于远离人口中心的地方。问题是我们管理电网的方式使得跨地区的输电线路几乎不可能建成。

Australia is more interested in $368 billion Submarines deal

澳大利亚对价值3680亿美元的潜艇交易更感兴趣

Canada has native UHVDC installations to send large amounts of power from the Nelson River at Hudson bay to Chicago, over 2000KM

加拿大拥有本土的特高压直流输电装置，将大量电力从哈德逊湾的纳尔逊河输送到芝加哥，距离超过2000公里

Chi doesn't need to satisfy 4-5 years election promises. It can focus on longer term needs.

他们不需要每4-5年搞一次选举，可以制定长期计划

I'd be very interested in the UHVDC transmission reliability. The NSW-VIC interconnector seems to fall over every time there is high demand in the NSW grid.

我对特高压直流输电的可靠性很感兴趣。每当新南威尔士州电网有高需求时，新南威尔士州-维多利亚州的连线似乎就会崩溃。

Kiwis have used HVDC since the 1960's as well.

新西兰人从1960年代就开始使用高压直流输电了。

greenfrog8871

with little exsting transmission infrastructure in place' explains the gap between China and everyone else. They started late and could 'jump' to the latest tech. Same thing happened with cell phones in Africa, they skipped the whole land line thing.

现有的输电基础设施很少，这解释了中国与其他国家之间的差距。他们起步较晚，可以“跳”到最新的技术。非洲的手机也是如此，他们跳过了固定电话。

As a Chinese I'm not sure if I'm right or not, as far as I know for example, most of the electric power companies in the US are divided by states and there are  too many of them, so it's difficult for them to peak the power resources between different states, and the power equipments are aging.However, China's power system is completely deployed and peaked by the national power grid in general.This makes the entire country's power grid run very efficiently.

作为一个中国人，我不确定我说的对不对。比如，据我所知，美国的大多数电力公司都是按州划分的，而且数量太多，所以他们很难在不同的州之间实现电力资源的峰值，而且电力设备也在老化。然而，中国的电力系统总体上完全由国家电网部署和调峰。这使得整个国家的电网运行非常高效。

In Europa there are tons of underwater HVDC lines connecting countries. Germany is currently building an underground one connecting the north to the South

在欧洲，有大量的水下高压直流输电线路连接各国。德国目前正在建设一条连接南北的地下电缆

China dominating uhvdc, hsr, solar, ev, wind turbines, batteries, nuclear, reforesting, nuclear,...

中国主导着特高压、高铁、太阳能、电动汽车、风力涡轮机、电池、核能、重新造林、核能等等领域……

 I think I am still a believer in the potential in a place like the U.S..

我仍然相信美国的潜力。

Another great video Rosie. I have seen a worrying article about possible blackouts due to diminished coal baseload supply here in Australia. Of course the govt response is to ensure gas supplied power is available. So I hope that our federal government is investing heavily in large battery storage as for renewable power to be available reliably and at an acceptable cost they are certainly going to be needed and pretty soon I imagine.

澳大利亚的煤炭基本负荷供应减少可能导致停电。当然，政府的反应是确保天然气供应的电力可用。因此，我希望我们的联邦政府大力投资大型电池储能系统，以可负担的起的价格供应可再生能源，我想很快就会需要它们。

I feel UHVDC would be beneficial in Australia by linking the grids around Perth, Karatha and Darwin with the grid in the South and Eastern states of Australia. This paired together with solar farms in the tropical north and in Western Australia could meet the demand of the eastern states in the evening. It seems a lot more viable compared to the plan where Singapore buys solar power production in the NT which would involve an even longer UHVDC link of around 3000 - 4000 KM.

我觉得特高压直流输电在澳大利亚是有益的，它将珀斯、卡拉塔和达尔文周围的电网与澳大利亚南部和东部各州的电网连接起来。这与热带北部和西澳大利亚州的太阳能农场相结合，可以满足东部各州晚上的用电需求。与新加坡在北岛购买太阳能发电的计划相比，这似乎要可行得多，后者将涉及到一条更长的、大约3000 - 4000公里的特高压直流输电线路。

I am surprised you did not list the project in North West Australia to supply solar power to Singapore. it has been held up by supply of cables.

我很惊讶你没有列出澳大利亚西北部向新加坡供应太阳能的项目，由于电缆供应受阻。

for ac or dc the current decreases with a higher voltage for a given wattage. If uhvdc suffers less loss in transport then its more efficient to use for other dc applications rather than converting dc-ac-dc

对于交流或直流电，给定瓦数时，电流随电压升高而减小。如果特高压直流在传输中损失较小，那么它更有效地用于其他直流应用，而不是转换直流-交流-直流

mickvonbornemann3824

Edison would’ve loved this, he had a big thing about DC.

爱迪生一定会喜欢的，他很喜欢直流电。

rogerterry5013

I think the link Norway to UK is UHVDC

我认为连接挪威和英国的是特高压直流输电

davidliddelow5704

There would be losses in the actual AC to DC to AC conversion too. I want to know how they do that and how it compares to regular old transformers.

在实际的交流到直流到交流的转换中也会有损耗。我想知道他们是怎么做到的，它和普通的旧变压器相比如何。

One serious and unanswered problem is the very common severe weather like baseball size hail and extremely high speed straight line winds. These are destroying solar panels on a massive scale. Some kind of protection needs to be developed right away. Some solar farms have been wiped out before even getting put into service. Whoever solves that problem will get quite rich and deservedly so.

一个严重而悬而未决的问题是非常常见的恶劣天气，如棒球大小的冰雹和极高速度的直线风。

它们正在大规模地破坏太阳能电池板。需要立即开发某种保护措施。

一些太阳能发电厂甚至在投入使用之前就被摧毁了。

谁解决了这个问题，谁就能发家致富

UHV transmission and energy storage devices are not in conflict; in fact they always appear as twins. There are hundreds of pumped storage plants under construction in China, along with various other forms of energy storage centers.

特高压输电与储能装置不冲突

事实上，他们总是像双胞胎一样出现。

中国正在建设数百座抽水蓄能电站，以及各种其他形式的能源储存中心。

Well researched and a critical assessment.

This is what we need for sensible decisions.

充分的研究和批判性的评估，这是我们做出明智决定所需要的。

daveh6356

Marine cables could resolve land access issues (& look better?) but with storage costs reducing I'm not sure if it makes sense.

海底电缆可以解决陆地连接问题(看起来更好?)，但随着存储成本的降低，我不确定它是否有意义。

vrealzhou

I've heard before that Australia is going to sell solar generated electricity to Singapore and I think that will need the UHVDC to transfer.

我之前听说澳大利亚要把太阳能发电卖给新加坡，我想需要特高压直流输电。

zollen123

Is it possible to have underground UHVDC power network?

是否可能有地下特高压直流电网?

grantpiper6358

great vid, but the environmental cost of batteries must be factored in, as per the environmental cost of UHVDC.   all those raw materials and manufacturing don't come cheap environmentally or energy wise.

但电池的环境成本必须考虑在内，就像特高压直流输电的环境成本一样。所有这些原材料和制造，从环境和能源方面看都不便宜。
