i guess im randomly asking but does any of you know of a tool to log back into an instagram account?? I somehow lost my account password. I would love any help you can offer me.
@Alan Konnor I really appreciate your reply. I got to the site through google and Im trying it out now. Takes a while so I will get back to you later when my account password hopefully is recovered.

Hi, I got the same question and I learned from a small case study that the j in Ii = Yij*Vij is not totally equal to the j in Ii =Yij *Vj. In other words, I12 is not equal to Y12*V2. There should be a point 3 in the completed circuit that is not shown in the slide. I12 would be equal to Y12*V2+Y13*V3. And I12 is indeed equal to (V1-V2)*Y12. I hope this helps.
Thank you, it's always beautiful when complex concepts are well explained and turned into natural words, excellent my friend, I hope I can watch more of these. The music is nice, but it'd be great if you decrease the volume a little bit. Regards.
I had a hard time following the last equation because of confusion of the j subscript. The previous equations were dealing with just two busses; with the subscript of i for the first bus and j for the second bus. How does j represent all of the currents in all of the busses. What does Yij represent and Vj represent in the last equation? How do all the phase angles of all of the busses figure into the last equation?
Richard, thank you for you time for asking your question. GeneralPAC is the platform where you can find hundreds of video tutorials on various power system engineering topics. Please consider subscribing and extend your support by becoming the patron at www.patreon.com/generalpac. The generalized formula that you see, and as what we have shown in the video, is a representation textbook authors use to simplify and tackle power flow equations. You would find this representation almost anywhere. This simplified form is used as an application for the construction of admittance matrices. You may find this video to be helpful as this video puts your query into an application. ruclips.net/video/jabxIoRwN5Q/видео.html To answer your question, let me answer that by breaking down some of your questions. This generalized formula pertains to the Kirchoff's Current Law which states that the sum of incoming currents should be equal to sum of outgoing currents. The j is a representation of N (all) number of busses that are connected to Bus i. This mean that if we consider I2, it means that we are referring to the current injected at bus 2. Yij represents the admittance that is present between two busses, so in the example shown in the video, it becomes Y12. Vj represents the voltage at Bus j with resepect to the reference node (and not the voltage difference). So in the video, Vj is the voltage that is present at Bus j. Since this is a summation between all of the busses at Bus i, and since all all of the parameters will be used in their phasor form, when you'll multiply these values and sum them up (as per the generalised form), you would end up with a final answer along with the phase angle of the current. I hope this answers your question and you are satisfied with our response. Please feel free to follow up with your queries should you have troubles in understanding the forementioned response. Thank you for your time. Best Regards, GeneralPac Team
In Power System Analysis course we will start from very basics: principles of Balanced systems, how power factor affects the performance of systems and techniques which we can employ to improve the power factor. In addition, you will build a strong concept on per unit systems and load flow analysis. This module consists of four parts, each building upon your knowledge based on previous ones.

@Alan Konnor It did the trick and I now got access to my account again. I'm so happy:D
Thank you so much you saved my ass !
@Jay Andres Glad I could help :D
Had no idea what my prof was talking about and now everything is clear! Thanks man

why is the current coming out of ith bus based on the voltage of the second bus ie. why is Y*V_J instead of Y*V_I or Y*V_IJ?
Hi, I got the same question and I learned from a small case study that the j in Ii = Yij*Vij is not totally equal to the j in Ii =Yij *Vj. In other words, I12 is not equal to Y12*V2. There should be a point 3 in the completed circuit that is not shown in the slide. I12 would be equal to Y12*V2+Y13*V3. And I12 is indeed equal to (V1-V2)*Y12. I hope this helps.
2:28 Regarding the bus voltages, are they line-to-line voltages, or line-to-neutral voltages, or phase voltages?
Bus voltages are typically line to line rated unless specifically stated as line to ground or phase. This is a common rule of thumb in the industry
your videos always help me a lot. thanks
+juyoung sim Thank you sir :) I'm glad it helps!
your videos and your minner are the best one give help me through youtube. thank you so much

may i ask that what the voltage stands for ?
line voltage or phase volt?
how about the current? i am really confused
Nice videos, helping me for my PE Exam
Very nice. Kindly upload lectures regarding Gauss seidel, hope I spelled it right.

@@Generalpac very 'good' answer.
How do i calculate the maximum power flow in MVA in the new transmission line and new receiving end substation
please keep the good effort! it is very helpful thanks
God bless you man. Very helpful

thank U very much....lam from iraq
i saw nearlly all the vedio that U done.
😍😍😍😍

Thank You
hye sir.when you wrotw Vi ( anglei) - Vj ( anglej)/Z, why does Z dont have the angle?
Great job, thanks alot!

what if you have a 3 buses ? (like triangle) what would be the equations ?
This method is often termed as
Inspection method
How to get hanbook?
I have a problem with a task that is about power flow
Please if they can remove the background music
Im sorry what is he writing for 'tilde'?
It would be better without the music thought
I don't mind the music that much tbh. this type of music is pretty relaxing, but I think it is very loud, lower the damn volume. lol
lecture was awesome but music wasn't
i love the music
👏
