One other advantage of HVDC for grid interconnects is that they also function as an asynchronous tie allowing the interconnection of two AC grids that would otherwise be incompatible because they operate at different frequencies, this is particularly important for grids that would otherwise be isolated due to the frequency mismatch with all of their neighbours. With the move towards more renewable generation it is only becoming more important for grids to work together as different grids have access to different natural resources for power generation and variety helps to balance out the individual fluctuations.

[@theMekanik]

Oh that’s great I never thought of that 🤭

[@ThalesMullerBR]

[@TheCarpenterUnion]

[@JessWLStuart]

I worked for a power company that utilizes a 850 mile DC line from Washington to California. The DC POWER moves at the speed of light (in metal - weird but true), but the individual electrons move very slowly. This DC line is about 50 years old. An individual electron that started at the north end of the line won't reach the end of the line for many more years (75 mile trip)!

[@Deepsingh-ok2eo]

Yeah because drift velocity of electron is pretty small

[@WJS774]

The "water pipe" analogy works pretty well for that; if you have a hose full of water and turn on the tap, the water starts coming out the other end almost instantly (speed of sound in water, I think) but the water itself is most definitely _not_ travelling over 1 km/s.

I work for a utility yet this made me understand the conversion process simply and clearly. Interestingly, we use DC conversion stations where we connect to some other grids. By converting to DC and back to AC we are able to handle frequency irregularities (that come from a utility that uses some of the longest HVDC power lines on the continent).

[@FayettiSiqueira]

Hi! Congrats on the video and your channel! I'm a power systems engineer in Brazil and allow me rectify some inaccuracies about HVDC (in Brazil there are 5 HVDC lines 2550+ km). The correct name is 'DC links' because it controls the power flow between two independent AC systems. For instance a hydro power plant and the national grid or two countries one 60Hz and the other 50Hz. We don't care about the wave form, we want to control the power flow over the line. To do that we control the SCR trigger. The HVDC doesn't work as a gigantic UPS. The terms 'rectifier' and 'inverter' are used when you have a hydro power plant because they indicate that the power is flowing from the rectifier (plant side) to the inverter (consumer side). It make sense because the power always flow from the plant to the consumer. But if you consider a link between two countries the power flow direction can be either way. Therefore, Edson is still wrong ;-) Cheers

[@MrMalthusMusic]

Thanks for your clarifications Ricardo! It's always good to hear some input from people in the field.

[@Vliegendehuiskat]

Not to mention the fact that Edison is also wrong because AC-motors are usually more efficient and have less maintenance than DC motors. This is not that big of an issue in most households right now, but it might become a huge problem is heat-pumps and bigger airconditioners start becoming more commonplace due to climate change and rising power-bills. The mechanical components are usually simply the biggest power-consumers in just about every system.

[@fmfs10]

Ei Ricardo! Sou estudante de engenharia elétrica, e me interesso pela área de transmissão. Uma dúvida básica que tenho sobre a transmissão DC: No controle da transmissão AC deseja-se uma maior ou menor corrente nas linhas devido a variações de demanda e também atenuação de efeitos capacitivos das mesmas. Para estes casos, basta a utilização de transformadores com mudança de TAP para controle de tensão. No DC, embora os efeitos capacitivos não existam, a quantidade de corrente devido a demanda ainda precisa ser controlada. Como é feito o controle de corrente nos cabos, de forma a garantir o fluxo de potência necessário?

[@FayettiSiqueira]

Felipe Magalhães o fluxo de potência no link DC é controlado pelo ângulo de disparo dos tiristores nas duas extremidades da linha, mas acho que a sua pergunta é mais ampla. Em todo sistema de potência existe uma 'barra swing' que absorve as variações de carga de forma a sempre manter a geração igual ao consumo, afinal não há como estocar energia elétrica. Podemos estocar a água dos reservatórios. Normalmente a barra swing é uma grande hidroelétrica que fica configurada para operar 'livremente' enquanto as outras geradoras ficam modo PQ constantes, ou seja ficam gerando sempre a mesma potência ativa e reativa. Espero ter respondido sua dúvida

[@TheSimoc]

While applauding, a little correction: sine wave, not sign :) And there is actually one thing to elaborate on the Mehdi's speech too, the shown inverter output is called "modified sinewave", which is a fancy name for that impure square wave, doped with deadtime between semicycles and voltage set near-peak value of the equal sinewave. There is also another, rather a glib inaccuracy in the video, using the MWO transformer in demonstration. It is bad for such, because they are famous for actually consuming whole lot of real power when idling. That's because they are not designed to ever idle - they always have the magnetron hard-wired in their secondaries. Thus they are designed with as little turns in primary as possible without the core saturating at the working voltage *with the voltage drop caused by the constant load*. Therefore, when they are "misused" without the magnetron-sized load, primary has the full mains voltage without the drop by the load, and the core goes into saturation and high real power gets turned into heat on primary.

[@Roxor128]

The evolution of HVDC conversion technologies has been from mercury-arc valves to thyristors to insulated-gate bipolar transistors in the newest installations. Turning it on and off at the rate of the AC grid works, but needs a lot of filtering to remove harmonics. Newer installations use multi-level converters which do a better job of approximating the AC sine-wave and thus need less filtering, and which in turn can take a big bite out of the cost of an installation.

[@GirlWhoCriedAardvark]

@@spidercubed9718 Some equipment uses the mains frequency to drive their clock (eg: old consoles, and even some modern electric clocks), it is actually quite a sensible source for a cheap, stable, known frequency ... until you ship your product to a country running at a different mains frequency, then your electric clock (or CPU clock) runs at a division/multiple of *that* mains frequency. So Sonic, programmed to run at 60 FPS (footfalls per second) in N-America/Japan, can now only run his little blue legs at 50 FPS* in the rest of the world. Luckily, the rest of the game is equally slowed down to match, so he doesn't notice. But the player does notice, as most people's brains aren't clocked to local mains frequency, (ElectroBOOM being the exception: since he is so often wired into the mains, it makes sense in his case.). * the relation to *real* FPS in terms of TV Frames Per Second is because analog TVs would sync. to the mains frequency, which is why it was *very* important for the power company to keep the frequency *very* stable (and synced at least across each broadcast region, as the transmitter also had to sync to the mains frequency so the TVs could receive its picture), which takes us back around to why the mains frequency was such a reliable source of cheap stable frequency ready to be used by console makers who didn't initially think of exporting their products globally then hit little frequency snags when they eventually did.

A long time ago here in Sweden they tried to distribute domestic DC in a few large cities (or perhaps just Stockhom?) but since DC is really prone to jump in order to create shorter paths - and the gas lines were running next to the DC lines, the results were less than impressive when enough jumps from DC lines to gas lines had eaten small holes in the gas lines and things started going boom a bit here and there... Lesson learned - DC ain't the same as AC - especially when it can jump over to other metal parts trying to find a shorter path ;)

[@12dollarsand78cents]

Wrong, it's how high the voltage is that is the factor that causes jumping or arcing.

[@jacklefevre9774]

AC crosses zero voltage 60 times a second which will break arcs, while DC does not. The fact that it's DC doesn't cause arcing, but it is far more damaging when it does.

[@MrCh0o]

I just loved the "things started to go boom here and there" part.

[@ManneSegerlund]

As an engineer working with HVDC systems this was great to watch. It sure is an interesting technology.

I think we should use DC because it's a much more positive way of doing things.

Thank you for this one. Learned something new. That and the video was once again hilarious to watch 😁👍🏻

[@flexopuppy]

When I first came across you, I thought you were a nut, I didn't really fully watch them....fast forward a few years...I actually watched one of your videos again after I got interested in electricity....wow, your way of teaching is top notch gold....I tried watching a university professor teach the same stuff and *yawn* that didn't pique my interest at all. You on the other hand I have been binge watching for 2 weeks. You make learning fun and entertaining. I wish you and your family all the best and want to thank you for all your hard work, I imagine doing it the way you do adds way more time to your day.

[@AnupamVipul]

wont you get square wave if simple diode method is used, in sine wave inverter we use IGBT with PWM signal to make Pure sine wave(How would one use filter to make sine wave from square ) . How does that phase shift transformer works & would it be possible to phase shift the generator it self as many power plants have more that 1 generator some even have 3 units which could allow 9 phase and reduce the size of capacitor needed to reduce ripple in the DC .

[@jjbailey01]

Diodes aren't voltage limiters or filters. They are on/off valves similar to a one-way check valve. Whatever the voltage is doing while the diode is on, aka forward bias, will be seen on the output. If the input happens to be a sine wave, you will see the peak of that same sine wave on the output of the diode while it is in forward bias.

[@emiliehans5225]

by the way, SCRs are also often called Thyristors or at least they're very similiar.

[@Danial3w]

From what I know thyristor is the name of the family that includes: SCR, ASCR, GTO and IGBT. it's like calling a BJT a transistor, which is.

[@the_ALchannel]

@@Danial3w no no, it's the other way around, some of the SCRs may use thyristors, but some may use IGBTs, triacs and whatnot

[@MarkTillotson]

Thyristor is common in the UK, probably portmanteau of thyratron (a gas filled switching valve) + transistor. Thyristors/SCRs are the only semiconductor devices capable of megawatt levels of power, and are heavily used for high power controllers for large motors etc.

It is nice to see a fellow colleague attracting people to EE, and physics principles. Plus, the funny (yet dangerous) moments of short circuits, and the correlated cursing 🤬 (I don’t blame him), are a sweet approach to keep the audience interested. As a personal side of the comment, this channel helped to keep entertained, and refreshing my basic knowledge on EE topics, and with a good mood, on my healing process from some surgery, thank you Mehdi! 👍🏻 PS.: You should consider about releasing a limited edition of a T-Shirt of “The Mother of the Fullest Bridge Rectifiers”, I almost had to return to ER due to internal bleeding, when you said it...

[@justace6844]

You could learn a lot from this one video.....

[@tommymac3029]

Great video, as always! So I noticed that placing a capacitor in series with the light bulb increased its light output. Makes sense as the 'off'' time is less as it flattens out the sine wave.. Why wouldn't a capacitor be used with AC powered bulbs to increase their output as standard practice? Seems like you would get the benefit of increase output without a penalty...? Less power consumption, heat, etc. at the same rated lumens...

[@michaelfortier7726]

You are using more energy to charge up the capacitor while lighting the bulb, which discharges between peaks. Think of the capacitor as a battery that you charge up while 'lighting' the lightbulb, the capacitor (battery) then powers the light bulb while the wires are providing no voltage, discharging it in the process. You then have to recharge the capacitor on the next cycle.

[@jwydubak9673]

The skin effect in overhead power lines is a bit less of an issue due to the structure of aluminum clad steel wires used. The wires are made of steel core, which carries the weight of the wire, and aluminum (which is lighter and cheaper than copper) shield, which conducts the current. Because of higher resistance of the steel core it is kind of useless for power transmission anyway.

[@PanduPoluan]

Basically, the engineers who designed the cables cheated 😆 Of course, the line inductance and ground capacitance still cause loss over significant distance. (Adding this just in case anyone wonders why DC transmission lines do exist.)
