He just summarized half my electrical degree in under 15 minutes 😂😂😂
Aren't you glad, that you spent your time wisely :')
rofl you right
You have no degree.
Honestly, this video is a great summation of everything that’s learned in the first two years of an electrical engineering degree. With that said, it in no way prepares you to do any circuit designs or anything, but it’s still a great video
I didn't even learn about HVDC during my degree.. Only now in my career I am
3 phase is ok for economy power
6 phase for sport power
12 phase for that ultra smooth luxury power.
BMW is in the electrical business now?
24 phase is for gods only
@@rollamanAE82 48 phase is for the gods gods
10 TRILLION PHASES ARE FOR DRIVERS THAT PRESS HARD ON GAS PEDAL IN FRONT OF BLM PROTESTERS AND ANTI FURRYIES!
1 phase anyone?
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.
Oh that’s great I never thought of that 🤭
That's exactly what happens in Itaipu. Their 10 Paraguay-side generators run in 50Hz and export 80% of their energy to Brazil in HVDC, then it is converted to 60Hz
But it does not matter? You can still convert AC to AC
@@Aguy644to a different voltage yes, very easily. But if you want to, for example, convert from 500KV 50Hz to 220KV 60Hz you need to convert to DC first. Otherwise you will get 220KV 50Hz, and what will happen is the same as in 5:49

Yup, M.A.F.B.R is just 12-pulse rectifier, while there are also 18-pulse and 24-pulse available. Some of them are RIGHT UNDER YOUR DESK!!! Powering the CPU with 1,5 volts or so, but hundreds of amps.
Not all hero’s have capes! Lol.
Came for the high voltage DC. Stayed for the full bridge rectifier.
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)!
Yeah because drift velocity of electron is pretty small

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.
Hi Mehdi...

Well played Sir. Well. Played.
Keep those hard strikes away.
Well, in europe the frequency is 50hz so I can pay even less money to the underpaid workers.
It's free real estate
But 50 hz messes with older electronics.
Ever hear of sluggish sonic games?
@@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.
@@vikiai4241 Love your explanations xD
Iam from Europe to but we got 50/60 hz
I live on a small island and the power is pretty "dirty." Our stove clock gains minutes every few days as a result, it's crazy.
It was fun watching you. Great video with practical examples.
Loved it!!!
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
Thanks for your clarifications Ricardo! It's always good to hear some input from people in the field.
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.
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?
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

I was just about to take sip from my morning coffee before he said that..
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).
Edison rolled 360 degree in his grave.

Hi, Mehdi! Related to the HVDC topic, there's one kind of measuring device used to measure the DC current on HVDC circuits, called DCCT, or direct-current current transformer (that is not exactly a transformer in the proper way). It's also refered as Hall Effect CT or Zero-Flux CT.
It would nice if you ever develope a video about it!
From a huge fan of your work and sense of humor, I wish you the best.
Sounds like an absolutely gigantic ammeter
Excellent video, I just had to make an presentation of Lines in HVDC, this video help me a lot. Greetings from Colombia
As a second year Electrical Engineering student, I'm so glad to have come across your channel, purely by accident. The amount of work you put into your videos is clearly evident, and it feels just like home. Keep up the good work :)
oh dude, im a second year EE student. grant me your wisdom plz im strugglin.
"sign waves are coming from city and square waves are coming from inverter, they are not in same shape and frequencies are slightly different"
"To connect them, they must be at same shape ,same frequency,same phase,same voltage level ,same background ,same ethnicity and graduated from the same school"
Underrated
👍🤣🤣🤣
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.
sign wave lol

@@Anomoomin or, for a lifetime of inefficiency and shame, a voltage regulator would work... unless, y'know... tubes.
but switches will be destroyed, no null point to help break the circuit.
.... If you really want, you can build a distribution level rectifier by taking the mains, converting it down to a highly regulated 12V, then using only high quality car audio equipment. Course then you'll have noise from the circuits that get it back to AC again.

@@shinji_27 I would rectify all the injustice of this world.
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 ;)
Wrong, it's how high the voltage is that is the factor that causes jumping or arcing.
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.
I just loved the "things started to go boom here and there" part.
I did my MSEE project on researching methods of measuring ions generated by HVDC power lines back in the '80's. I haven't thought much about them since then :-) But I LOVED your video, you are hilarious!

Very informative but hillariouse I love your videos I have never laughed so much Tim from Australian
Thanks for the practical demonstrations it helps to understand...
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 .
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.
@@spidercubed9718 yup. And?
When I was a EE college student, we went on a tour of power generator plant that converted to HVDC which transmitted to California. Got to see all the massive MAFBR equipment -- it was pretty cool. I guess they didn't care about liability issues back in those pre-historic days.
Edison: As I always intended. :D
EB: GET OUT! >:(
Very informative. Thank you for making this video. :)
by the way, SCRs are also often called Thyristors or at least they're very similiar.
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.
@@Danial3w no no, it's the other way around, some of the SCRs may use thyristors, but some may use IGBTs, triacs and whatnot
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.

Ya electro boom is back Jackson I love your videos more and you have knowledge you eat my head but I got some knowledge thank you
🔥🔥🔥Mehdi is on fire today🔥🔥🔥
I wish I knew as much as you about electronics. I would build so many things! I've got ideas and like to make things but I'm not as electrosmart as I want to be.
Like your videos! :)
We have quite a few UHVDC lines in China, with the highest been 1100kV 3200km transmission line. I remember there were quite a few debates when State Grid decided to go for UHVDC.
