Abstract

A modern electric power system network (PSN) is typically a large and complex engineering system whose healthy existence is crucial to industrial and socio-economic development of Nations. Voltage instability contributes to large extent to the system collapses or blackouts. It is a major concern for today’s electric power system operators. The Nigerian National grid (NNG) experiences on an average of thirty-five (35) system collapses every year over the past ten (10) years. This paper presents a review and classification of system collapses experienced on the Nigerian National Grid (NNG). It also reveals that on the average, the fault induced system collapse is about 88%. This implies that the NNG is highly venerable to voltage instability than other form of disturbances.
