Damping coeffcient
Damping coeffcient
(OP)
I found the following information in transmission grid code that
Generator Excitation Control System
・・・Control performance of the voltage control loop shall be such that under isolated operation conditions the damping coefficient shall be above 0.25 for the entire operating range.
Could anybody suggest the best book to explain damping coefficient for voltage variations?
Is there any standard code for this ratio? Why 0.25 is selected why not 0.1?

RE: Damping coeffcient
The definition of damping factor of an eigenvalue is the (negative of the )real part of the eigenvalue over the magnitude of the eigenvalue. Therefore ranges from 0 to undamped to 1 for critically damped.
There may be a more practical expression in terms of voltage control parameters that I am not aware of.
