Thank you for your comments. Both are very valuable and provide great points of view.
I think I'm going to do both and see what comes out of this. Our situation is similar to Ireland in the sense that we are an island, with relatively low inertia. Our renewable integration is expected to be...
Dear all,
I’m trying to do a simplified analysis on how the integration of renewables into the transmission system would impact stability and critical clearing times.
Consider this -- Most of renewables have limited (if any) inertia and have also limited ability to respond to system...
I've heard this few times before and I wanted to share w/ you this comment.
Is it necessary to set the droop value (R) in each machine of a control system to the same value? Most of the machines in my control area are set to 5%.... It seems to me this value is specific of each generator...
I know that GE - PSLF and PSS/e are the main players for transmission system planning software... but I was wondering if Powerworld has already become the standard software for transmission planing somewhere in the USA (or in the rest of the world for that matter).
Back when I was an intern at...
I've been asked this question several times before and yet I'm not clear on how to answer this.
For some System Impact Studies, developers often ask about equivalent Inertia Constant "H". For an estimate, I just convert all generators H's to same base and add them.
Now for Damping Coefficient...
tlrols,
Thank you for your reply. I used Powerworld during college and during an internship at ISO-NE......it was a great program. Great GUI, very intuitive and the help section was very useful. Unfortunately, the utility where I'm working uses PSS/e.
Do you know if Powerworld has already...
Hello guys,
I've been a transmission engineer for a few years now, and most of this time I've been using PSSe as my main analysis tool. I think it is an excellent software for power flow and stability analysis but its learning curve is a little steep.
Now most of my work, I do it manually...
mgtrp:
It's a rather large system >2000 MW of installed capacity with a 230/115kV transmission system.

I have the individual H values for each unit. I'm looking for an equivalent value (or aggregate) of the system.
Thank you for your help!
Hello guys,
I've been asked to provide the total system inertia (H) of my power system. This is for a dynamic stability study. Any ideas on how to calculate this number?
Thank you!
