No matter what you do, those two voltages can't be in phase as there is the line inductance itself playing an important role in deciding this. Also, if these two voltages are in phase, the line won't be able to deliver reactive power which depends on sin δ and if δ is zero then that means no reactive power.
Qs=Qr is an assumption because we considered that both the sending and receiving end voltages are in-phase which means δ=0. But in reality, that doesn't happen because that would mean no flow of reactive power.
@@ervivekchoubey , Reactive Power flows mainly due to the Volage difference in the Magnitude not because of the 'δ'. If 'δ=0', it implies that there won't be any active power flow
@@ervivekchoubey my question is regarding why generator side which is sending side also have shunt reactors in many 500kv grid stations ? This question is not related to your video
@@ervivekchoubey as you have explain in your video that receiving side have shunt reactors install. I have also seen sending side also have shunt reactors install. Can you explain why sending side have shunt reactors installed?
This could be the case for maintaining steady state stability and to maintain maximum power transferrable. Pmax is inversely related to line reactance so shunt reactors reduce the reactance causing Pmax to go up which helps in higher power transfer. Also the alternator is saved from supplying reactive power to the line as that would affect the power factor. So the necessary reactive power is injected by the reactors.

Thank u broo
Sir one make a video sending end receiving end how much power losses .. how???
Okay I'll try. Thanks 👍
May I want to know that the sending end voltage and receiving end voltage are still in phase after shunt reactor is used?
No matter what you do, those two voltages can't be in phase as there is the line inductance itself playing an important role in deciding this.

love it mate
Thank you
Nice
does the apparent power on the sending end side Ss equal to Sr as Qs equal to Qr?
Qs=Qr is an assumption because we considered that both the sending and receiving end voltages are in-phase which means δ=0. But in reality, that doesn't happen because that would mean no flow of reactive power.
The assumption has been made to simplify the solution.

Sending side also uses shunt reactor why?
In which part of the video? Please mention time-stamp so that I can help you better.

Awesome
Good. Video
Thanks 😊
