The 'Equal area criterion' for the determination of transient stability of a synchronous machine connected to an infinite bus  (1) ignores line as well as synchronous machine resistance and shunt capacitances.  (2) assumes accelerating power acting on the rotor as constant.  (3) ignores the effect of voltage ... inherent damping present in the machine.  (4) takes into consideration the possibility of machine losing synchronism after it has survived during the first swing.
