*CRITCAL CLEARING ANGLE
The critical clearing angle is defined as the maximum change in the load angle curve before clearing the fault without loss of synchronism. In other words, when the fault occurs in the system the load angle curve begin to increase, and the system becomes unstable. The angle at which the fault becomes clear and the system becomes stable is called critical clearing angle.
*CRITICAL CLEARING TIME
The Critical Clearing Time is the maximum time during which a disturbance can be applied without the system losing its stability. The aim of this calculation is to determine the characteristics of protections required by the power system.
