Transient stability limit of the Nigerian 330kV power system was assessed in terms of its ability to maintain synchronism among the generating units. The Power (angle) stability limit and voltage stability limit, before, during and after system changes or disturbances were also assessed. The 330kV transmission network was analyzed using the Runge Kutta Method to determine the critical clearing angle and the corresponding critical clearing time. It was observed that a critical clearing angle of 12.85 ͦ with critical clearing time of 0.1s gave a more stable result than a critical clearing angle of 166.376 ͦ with a corresponding critical clearing time of 0.363s. It was therefore recommended that faults on the network be cleared as quickly as possible so as to maintain the system stability. (Key words: Power (angle) stability limit, voltage stability limit, synchronism)
