Abstract
The paper is concerned with the effect of clearing time on the transient stability of a 2-machine system. An equivalent electronic analog interconnection for the equations of the system is used for the solution of the problem. The analog is based on a modified form of Park's equations and it allows for the variation of field flux linkage with time during a transient disturbance. Results of a sample problem show boundaries of stability as functions of clearing time for different positions of a 3-phase earth fault.
