What is the normal value of delta in rotor angle stability
or transient stability?
Why it selected so?

Answer Posted / iamdon

The normal value of delta(load/power/torque angle) is 30
degree.

This is selected so because during power swing (in case of
instability) the flactuation of delta is in the range of +/-
30 degree.This will result the range of delta in 0-60
degree.In this region(0-60)sine curve is linear.
