Sir, how to watch rest of vedio lectures - power system stability ?

[@harshakotuwegedara]

Sir How to access the other parts of the lecture series from Critical Clearing Angle .. it says members only.. how can I become a member. I love this series. ❤️ You explain them in detail and that makes very clear these concepts to me.

@29.27 sir u explained very well ma'sha Allah ... I've doubt about how b/e the interval 'a' and 'b' the magnitude of Omega is increasing although b/w the same interval Omega is decreasing due to deceleration.. Please explain.

[@DrAfrozAlam]

From point 'a' to 'b', magnitude of relative speed of rotor (ωr) with respect to reference speed (ωs) increases as the speed of rotor (ωr) decreases due to deceleration.

[@DrAfrozAlam]

Please keep in mind that rotating reference axis rotates at synchronous speed (ωs). Delta (δ) is relative position of rotor with respect to this rotating reference axis. Therefore, first derivative of this delta (δ) gives relative speed of rotor with respect to speed of the rotating reference axis (ωs).

[@prarambhiksur2104]

Sir I was having doubt while solving problems. Does the maximum swing of the rotor Delta(m) has to be any point after critical clearing angle or it is the point beyond the critical clearing angle where electrical and mechanical power of after fault curve is same?

[@AnuragSharma-ip1fs]

[@oktavianusvebrianto1336]

Very well explained sir, I have a question sir. What is the impact of high pv penetration on rotor angle generator? Thank you

[@oktavianusvebrianto1336]

Whether when the pv dispatch, rotor angle will decrease? And with the same load condition, when pv outage rotor angle will increase?

[@DrAfrozAlam]

Power injection at any bus by pv will be treated as negative load. So, its effect will be similar to that of reduced load.

[@subhajitghosh8221]

Dear Sir, In JB Gupa power System book, it is mentioned that Equal Area Criterion is also applicable for 2 machine system but not directly applicable for multi machine systems. As per your lecture this technique is limited in 1 machine system. Which statement is correct ? Sir.

[@DrAfrozAlam]

Let me know the time stamp in the video lecture where I said this.

[@subhajitghosh8221]

Between 0.55 and 1.05 minutes , I think I interpreted your words incorrectly, pls check this. Sir.

[@DrAfrozAlam]

I said, without solving this equation (Swing equation), we can decide whether the system is having transient stability or not, if the system is simple. Just (such as) a synchronous machine connected to an infinite bus.....
