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



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

Answer / 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.
