    The security of power system operation is a measure of its reliability; hence the planning and real-time operation of power system requires regular security assessment. This paper presents a dynamic security assessment of the Nigeria 330 kV power network. It considered the installed capacity of the power system alongside the available capacity as well as network structure in terms redundancy for flexibility. Some weak areas of the system were identified and the security status of the network assessed under large disturbance condition. Results match expectations as the system’s response to impressed contingencies were discussed. Feasible corrective measures proffered for improved system’s security.
