Sir, the sessions on capability diagram are very worth and thanks to you for that. However there is one more limit that is stability of gen on leading pf. This is also called Rotor angle limit or minimum excitation limit.
Hello sir, Let us consider a case where the turbine is able to provide active power greater than the generator MW rating. Now keeping the MVA rating constant, if I intend to increase the MW rating beyond the designed generator MW rating by improving the power factor then can I run the generator continuously at slightly increased MW??
thanks sir.....one more topic....is easily understood.........one question sir:- in last moment u said....suppose P demand=35 kW.....so u drew a line....parallel to Q axis.....but this line cuts the capability cure in 4th quadrent also....where Q is -ve......so whats thats interpretation ???
As of now I am wrapping up the course, bcz I have to start with synchronous motors as well, other topics I may cover in future. And anyways with the knowledge that you will get with the lectures I have put, you can easily understand the topics...
and sir.......In Alternator.....it always ....supplies....P and Q ...so its always positve ??so arnt we concerned only about the area in the 1st quad only.....bounded by......P axis , Q axis ...locus of De and locus of S???
Best teacher. Im watching the video from bangladesh, from buet, a favourite university here. ❤
Very nice explanation sir
Wonderful explanation!
From
Student of
Dhaka University of engineering and technology
Good lecture
Very nice explanation and good concept given

Thank sir......this is v v helping for technical concept
really informative lecture,thanks sir
Sir, thank you so much ❤ u r amazing u helped me so much with my exam 🌹
Sir , how are you shifting S to Q axis? And same with DE
Kindly go through the previous lecture..which explains the theory...
How to choose the scale for drawing? Can we choose it random. also why s curve is not completely drawn in the third quadrant.
Hello sir,

Now keeping the MVA rating constant, if I intend to increase the MW rating beyond the designed generator MW rating by improving the power factor then can I run the generator continuously at slightly increased MW??
when we plot armature power curve 50 kva , we use kva , but when turbine power is used, it is used in KW. is it right?
Definitely I will do sir

Yes depending on the excitation reactive power can be positive or negative...
Sir is it possible to take lecture on voltage regulation methods and two reaction theroy then slip test
As of now I am wrapping up the course, bcz I have to start with synchronous motors as well, other topics I may cover in future. And anyways with the knowledge that you will get with the lectures I have put, you can easily understand the topics...
Ok sir
Sir, I understand about why reactive power negative and Positive value but i didn't understand what to interpret negative real power power...
that's just the machine producing real power (generator) or absorbing real power (motor)
and sir.......In Alternator.....it always
....supplies....P and Q ...so its always positve ??so arnt we concerned only about the area in the 1st quad only.....bounded by......P axis , Q axis ...locus of De and locus of S???
The reactive power depends on the excitation...it is all there in the lectures...
oh yeah.....got it
It's ok sir... No problem.... Start lecture on synchronus motor....
But that no excuse of not trying the topics on your own...😎
