Abstract :
A novel method for steady state stability analysis of synchronous machines is presented. The method is based on a novel swing equation, which is a second-order, nonlinear differential equation. Two steady-state stability criteria can be derived by evaluating the eigenvalues of a linearized version of the new equation, one of which is for step-out instability and the other for hunting. Although these two instabilities have mostly been discussed independently so far, this approach makes it possible to handle the two instabilities on a common basis
