| 2021-09-24 12:49:40 -0500 | asked a question | Has anyone checked the damping ratios from the channels in the .out files? ERCOT's Planning Guide says to "ensure that power oscillation within the range of 0.2 Hz to 2 Hz decays with a minimum 3% damping ratio." (S 4.1.1.6) Does anyone know how to check for the freq. range above and the damping ratio for a large number of .out files containing many channels? I'm using PSS/E. |
