Wonderful explanation, doing a project on this subject and this explanation covered a lot!
Thank you, beneficial video to understand the HVDC
I just found your website sir . And I have to say It is fantastic , I recently Got a Job in State Power sector , I am looking forward to use your Website for sometime.
Thanks again , By keeping price low in Swiss franc , You might not know but It is affordable in India too , that's 1660 Rupees for 1 year . NOT that cheap , but it is under affordable range . Thanks
Thanks for your kind feedback. I was on business trips to India many times. I visited State Power Grid Cooperation as well and I keep it in my best memories. I am looking forward to see you on my website. All the best!
Nice explanation with good circuit diagrams..
Thanks for the feedback. Please forward it to your teams so I get some more views! All the best!
Your very first explanation about AC transmission reveals that you do not understand transmission lines and characteristic impedance. Thank you for making this your first point as it saved me 8.5 minutes of potentially wasted time.
I admit that the AC introduction is oversimplified and much too negative, today I would certainly choose another approach to make the case. However the transmission losses above 1000 km are significant. The main issue however as you know is stability, which can be overcome but at increasing costs per line length. Maybe I will rework the video.
@@georgschett801 No, you didn't oversimplify. Transmission lines are simply not lowpass filters. They have no inherent bandwidth limit. If they did my work with coax cables at 60GHz would never have been possible. Your error is a common one however and stems from imagining them to be comprised of lumped elements. This analysis can be made to work, but only by allowing the number of elements to tend to infinity. So please, don't use this analogy - better to say nothing than feed erroneous ideas into the minds of those that may one day need the correct models.
Everything you say is correct. You are obviously a HF expert! Pardon me however if I still use the simplification. In power system analysis we often use a simple lumped LCR models for power flow analysis. The lumped models give quite good results for shorter transmission lines. If however we need models for longer lines, higher frequencies (switching impulse, lightning), Ferranti effects or compensation of reactive power more accurate models are used. I myself use a type of Bergeron distributed model which is common in programs such as EMTP or ATP. I guess you use similar models based on surge impedance characteristics. So again, I exaggerated the losses with my introduction and there I fully agree with you.
Thanks , it was great job
Power loss in the converters, especially when thyristors are used. Thank for the presentation.
Students do not to try these things using voltage sources, resistors, inductors, capacitors, diodes, etc., just computer circuit emulators.
Very usefull tutorial, thank you
Glad you liked it
great explanation !
Thanks for the feedback!
what software do you use to build that cirucits?
you are soooo Incredible! thank you!
Excellent explanation!!, Thank u for your share your knowledge. May you share your simulation please, all is with educational purposes. Regards!!
Nice presentation it will help me review my Electrical Engineering knowledge...
Thanks for the kind feedback. All the best!
@@georgschett801 How I wish I can also share my knowledge by creating presentation similar like this....
@@DONGNESFAMILYTV Why don't you start it? Choose a topic an go! Over time you will get more and more people watching.
@@georgschett801 Thanks for the cheers I already choose my topic and just need to develop my lesson plan and give more need more time. At present I'm still busy supporting outage in our place and have limited time. Also Im still trying to learn basic editing skill with Premiere...
Good explanation.
Thanks for the feedback!
Nice and clear explanation
Please let us know which software you are using for simulations
www.ecsp.ch. You can directly click on the link in the first comment under the video. It is browser based, no download needed. Tested browsers: firefox, chrome and opera. Internet Explorer is not working.
The siphon sound 😭
Hi Georg, thanks for a very useful video. Is there a specific reason why you chose not to talk about ignition angle and commutation overlap in this basic instruction? I myself find these concepts key to understanding the workings of HVDC converters. Best regards
Dear Andreas, thanks for your comment. Your question shows that you are an insider. However most watching this video may not be that deep in the subject and just want to get a basic overview. For many it is already at the edge, for others it is too simple... All the best
1.06 seconds everyone xD
are you using MATLAB?
No but I use www.ecsp.ch
The Flush destroyed the ac!!😂
Please permission to share sir! Thanks
Sure!
1:03
hi
1:02 are you kidding me???
Why should I? It is a fact that for very long transmission corridors HVDC is far superior to HVAC. You do not agree? So the flushing sound is just a joke, pardon if it was irritating.
Something is wrong with the sound -- the level goes up and down. Very irritating and ruins an otherwise good video.
Yes, sorry for that. It was an early video and I hope that the newer ones are now better.
Be a little more clear to make the ordinary understand too.
Sir, thanks for your feedback. This channel addresses people who have a background in power system technologies.
