#24 Operation of Synchronous Gen with Infinite bus #2- Effect of changing mechanical torque (easy)

[@avisekhghosh2757]

mafia example fits so relatable here, thank you sir for this amazing explanation , never gonna forget this in life

[@ElectricalisEasy]

Glad to be of help..please also do consider sharing the videos with your friends and anyone who might find them helpful

[@shivamkhare205]

Mafia Analogy 👍👌 You nailed it 👏👏

[@ElectricalisEasy]

Thank you..

[@shivamkhare205]

Varun D Nair Seriously Mate, if anybody on You Tube deserves floods of views, likes and shares, it's certainly you. I know action n result oriented people like u are often least interested in praises still the Engineering must exactly be taught the way you've chosen to teach us. Kudos again !

[@NareshCh2]

TRUE.

[@gurusumanth480]

I too concluded that u r a machine's story teller

[@cholomsury1548]

Hahaha sure I also like that story

[@KKD220]

So easy explanation by you 💯 🔥👌 thanks sir

[@surendrakverma555]

Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@S-MKim]

The excitation condition here is that the mechanical torque of an engine seems to be increased to a higher value, not a short period of push acceleration. To meet this mechanical power increase, the angle delta is subsequently increased in the electrical power P_G = Ea * V * sin(delta) / Xs.

[@Invisible_Tri]

Hi sir, Please i request you to keep making videos on various topics.

[@ErfanHossainShoaib]

Great story between Mafia and chota DON

[@ElectricalisEasy]

Glad that you have liked it..please also consider sharing the videos with anyone who might benefit from them..#sharetheknowledge

[@asfandyarimtiaz7322]

Firstly, thanku so much for your enormous contribution to the entire student fraternity. Sir at 8:00, it's Ex= Ea - Vphi. Not the other way round. Secondly, this phasor diagram at 8:05 seems faulty sir.

[@ElectricalisEasy]

It was a typing mistake, the vector diagram is correct...no it is not faulty, a detailed vector diagram is there in the following lectures..

[@writtiknath2226]

Only the equation is faulty

[@lifeiscrazy5722]

Yesterday i was struggling with the concept to remember.But mafia analogy did it. Now it will run throughout in my mind the entire life. hahah. And sir which tool u use to write in windows journal ?

[@ElectricalisEasy]

It is a digitiser from a company called huion

[@niazislam5745]

Awesome explanation.. thanx a lot

[@ElectricalisEasy]

Glad to be of help. Please do consider sharing the videos with your friend and anyone who might the videos helpful

[@navneetkumarsabre7275]

Now i think i can become mafia... 😂😂😂🤣🤣❤️❤️

[@petchu2002]

Thanks for detailed information. please clarify about pole slip or out of sync..when we change mech torque shifting of E causing load angle increasing..at which angle it is consider as pole slip?please explain about loss of excitation also by Mho diagram. If already have link please share.

[@qaz1234ism]

Why reactive power only flow from load to source and source to load? But active power flow from source olny why?

[@ElectricalisEasy]

active power is the useful power consumed by the load by definition, whereas reactive power is stored as a magetic / electric fields

[@carultch]

Reactive power is stored in the load, and consumed at a later part of the AC cycle.

[@MOKRABachour]

is it possible for delivering active power to mafia we make over excitation cash? i don-t think so? there is no relation between Active power and excitation cash.

[@alfaily6864]

Hello my friend..I've question hopefully to answer it please..why the induced EMF Ea of generator that to be synchronize is in phase with the V phase of the infinite bus?

[@krakash4474]

Bcoz it's equivalent to no load condition, hence induced emf and terminal voltage will be in phase. Or in other words u can say there's no current so no reactance drop.

[@neminathnarule2257]

Amazing lectures please make lecture on v and inverted v curves sir

[@ElectricalisEasy]

It’s already there in the channel

[@razzakahmad8731]

sir you said in one of your lecture the delta angle is in between 15 to 20 degree so my question is if we increase the mechanical torque (of PM) can we surpass this angle limit and this question came in my mind because we are dealing with large power systems so is it practically possible? btw thanks for your lectures they are extremely helpful.

[@ElectricalisEasy]

If you go above a certain value of delta the magnetic locking between stator magnetic field and rotor will get lost..and the generator will fall out if synchronism...

[@zaheersuhabuth2677]

What happens to the energy produced by the "floating alternator" alternator?

[@piyushkumar-wg8cv]

SIR, I AM CONFUSED WHY INCREASED STEAM INPUT WILL CHANGE TORQUE AND NOT THE SPEED, PLEASE HELP. BECAUSE IF SPEED CHANGES THEN MAGNITUDE OF EMF CHANGES.

[@simondemarque2826]

Power by steam turbine = steam flowrate * enthalpy drop inlet-outlet(often the condensor) Power by steam turbine = Torque * angular speed Angular speed = cst (varies between 49 and 51 Hz at most) defined by an ultra rigid electrical grid and the fact that we have a synchronous build machine Torque on a synchronous generator = proportional to the angle difference of Ef vector (exciter) and Ea vector (stator) = beta Electrical power delivered =(prop) Voltage * current Voltage on grid, and generator outlet is kept constant by AVR (automatic Voltage Regulator) current in stator will therefore increase to match the increase of power at constant voltage by increase of beta Hoping this will give an overview

[@gustavomarcelo7250]

Sir. You showed that P = EaVsindelta/X, hiwever you said increasing the excitation will not change the P. Will that change the Ea to be higher and P based on the formula?

[@kandukuri.narasimhabhagath9089]

In which video you have told under excited and overexcited plz reply

[@saratmondal2000]

kzbin.info/www/bejne/oGGppaiOZaZ5qcU in this he explained this topic

[@comandernehal8567]

at initial, "Applied Torque> Induced Torque" but when "Applied Torque= Induced Torque", both rotates at "Ws" speed. Is this "Ws" speed is after applying the "Torque" of the prime mover ? confused !!!

[@ElectricalisEasy]

It is the synchronous speed once the system settles down....

[@rujutakulkarni3770]

Very nice

[@Vijithc-sn6co]

❣️❣️❣️❣️

[@SivaKumar-AoT]

Sir, can your lectures be used for GATE ? ( I've seen a few lecture. Oh my god they are excellent !!)

[@alexrosca860]

So, can I buy manpower with cash or not?

[@YasirAlHasan--]

where is mafia goes

[@ktn8489]

In lecture 24 vector sum will be Ex=Ea-Vphi and not Ea=Ex-Vphi

[@Ramkumar-rs5gv]

Why we use damper .In alternator

[@AMAL_JOY.]

Sir when will you come live in KZbin next time?

[@ElectricalisEasy]

Haven't done a live in a long time...let me see...

[@AMAL_JOY.]

@@ElectricalisEasy thank you sir

[@anilprasad8654]

Sir I can't understand that how Ea=Ex-Vphi 🤔pls explain🙏🙏

[@TheSwastikcool]

that's a silly mistake

[@zaheersuhabuth2677]

It's a typo. It's actually Ex = Ea - Vphi....just like many reading this are wondering :)

[@ktn8489]

It is typo mistake as already replied by Varun Sir,

[@SayeemB-329]

How Ex=Ea-Vph has become Ea=Ex-Vph..??

[@ktn8489]

It is typo mistake

[@mdabid.8941]

sir real Engineering to idhar hai college to bas naam ke liye hai!

[@Rampo-gg]

This feels illegal💣
