| Abstract | ||||
| The transient energy function method is used to determine the critical clearing time of a power system. In this method, the critical energy is determined in terms of the rate of change of kinetic energy. For fast computation of critical clearing time, angles and speeds of system generators are predicted through Taylor series expansion. Barly computed critical clearing time is used for choosing the proper failure time of backup protection, to prevent both of system instability and false triping of protective relays. The proposed algorithm is applied on two power systems. The first system is used for comparing results, while the second represents Delta region of unified power system of Egypt. | ||||
