Tiivistelmä
Thermal electrical power generation is one of the major methods used in Egbin thermal station. Due to inconsistency and failure in the power supply in Nigeria, there is a need for a proper operation and maintenance schedule strategy of the various kinds of power plants accessories so as to facilitate their efficiencies and functionality.
Egbin thermal station, which is one of the major power generating stations in Nigeria
was used as a case study. The station has an installed capacity of 1320 MW
consisting of 6 units of 220MW each. It is in the generating sector of the Power
Holding Company of Nigeria (PHCN) which is the state owned Electric Power
company. Egbin thermal station was commissioned on 11th May, 1985.
Thermal electrical power generation is one of the major methods, used in Egbin thermal station. The major components of Egbin thermal station are boiler, steam turbine, condenser and the feed pumps.
The objective of this research was to study and enumerate profound solutions in order to
minimize the risk of failure and effectively manage the reliability of the substation
equipment, stemming from a proper maintenance strategy.
The operation and maintenance of Egbin Thermal station was examined and the conclusion was that it was challenged with insufficient Gas supply and restrictions, poor water quality and breakdown of two units due to boiler explosion in 2007, causing power generating plant to be shut down creating a 880 Mega Watts drop in power generation in the whole country. This occurrence has had a massive setback on the power plant, hence a proper maintenance strategy needs to be designed to curb the effect and develop a long lasting solution to prevent further potential disaster.
