Wow amazing explanation actually I got frustrated on my notes n opened utube n found u sir.. Am very glad

Bravo Dr. Afroz Alam. From California, United States studying for the Professional Engineering Exam - POWER.

[@strengthenmyself7492]

Well explained sir... This is an clear explanation Because of your video... there's no need to memorize all the equations

[@Imran52Feb]

A beautiful explanation of this very interesting topic, sir! Especially because this involves balancing Mechanical Power and Electrical Power. We meet our old friend I, the moment of inertia, which replaces m in case of rotational motion. A good revision for me. The power of calculus is very much evident here.

Assalamu alaikum sir Thank you so much for this explanation, I have a question if you can help me. I want to simulate the third-order model of the synchronous generator, but I don't know how to set initial conditions: 1- delta (angle of d-axis ahead of a-axis) 2- e'q (transient internal voltage of armature) 3- Tm (mechanical torque) 4-omega (rotor speed) I would be grateful for your help

[@ankurchakraborty394]

[@lulzsec4438]

Assalamu alaikum sir! Thank you so much sir. I was wondering KZbin video lectures for my conceptual understanding I found nothing that can give us clear cut understanding. But after watching your lectures doubt clear completely. Nothing can compare with these lectures. Best content on KZbin. Sir I'm preparing for the Gate 2020. If I get any doubt can I WhatsApp you sir?

[@GermanGonzalez-kv7xe]

Dear Dr. Afroz Alam, your are a wonderful teacher, Congratulations! I have the following doubt, in every text book I have checked and in your lesson No. 5 related to Power System Stability, Swing Equation, everybody multiply the accelerating torque equation by wr to get the accelerating power Pa, ie Ta*wr = Tm*wr + Te*wr, being wr the angular speed of the rotor a mechanical value, is it correct to multiply Te by wr to get Pe? if the number of poles is 2, this would be correct because wr = we, but for higher number of poles we = p/2*wr, we > wr.

[@DrAfrozAlam]

Don't forget that mechanical equivalent speed of we is wr.

[@edmarsalvador2673]

Thank you!

Very great lecture !!!!

[@teneeshunniap1]

Sir, why it is taking into consideration that mech torque and electrical torque are opposing

[@EkochuJosephAbeja]

GOOD JOB SIR

[@tjjanarthananx]

Sir, Sorry for asking non sense question. But I have this Doubt in PSS. What Mean First derivative and second order derivative at Disturbance.? People Say due to Disturbance we Should Differentiate the Equation. but why should we Derivate second order? or Should I Studies Some other Topic Please Refer me.

[@DrAfrozAlam]

For more clarity, please watch "Power System Stability- Part 1" and Part-2.

[@gustavomarcelo7250]

Hi Dr. For the theta = ws (t) + delta, why does the first integral and second integral it becomes d ( delta )/ dt and d2 ( delta) / dt2 instead of 0? If we differentiate a number or constant, it gives zero but why does delta is not zero, even ws is zero when we differentiate it the second time considering now it does not have " t " dependant and now a constant. Hope you get what I mean

[@DrAfrozAlam]

Dear Gustavo Marcelo, Of course Delta (𝛿) remains constant in steady state. However, during disturbance, it starts varying as rotor either starts accelerating or decelerating. So, during disturbance, Delta (𝛿) becomes variable. For more details, please watch my following video lecture: kzbin.info/www/bejne/hnXIk3l5p8trgJo

[@lulzsec4438]

Delta is a function of time. That is why it wasn't zero. You can't say a function's 1st or 2nd or 3rd order differentiation is zero without not knowing the exact function.

[@alawimidher5899]

Thank you Dr.Afroz for the very helpful series. I have a question that maybe be slightly out of scope, but Since generator's electrical power increase inherently in the event of a disturbance, at exactly what point the governor has to intervene and burn more fuel (in traditional generation) to increase power to the prime mover ? In other words, when does this automatic power compensation stop and external power needs to come into the picture.

[@DrAfrozAlam]

Governor automatically observes and regulates the fuel input needed to meet the load upto the maximum generating capacity of the alternator.

What is tha answer of step by step solution of swing equation?

[@DrAfrozAlam]

This is an approximate method used for solving 'Swing Equation'. By using this, one can also calculate 'Critical Clearing Time' corresponding to 'Critical Clearing Angle'.
