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 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!

Thanks for the feedback. Please forward it to your teams so I get some more views! All the best!

Glad you liked it

@@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...

Thanks for the feedback!

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

No but I use www.ecsp.ch

Sure!

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.

Yes, sorry for that. It was an early video and I hope that the newer ones are now better.

Sir, thanks for your feedback. This channel addresses people who have a background in power system technologies.
