Operation and Maintenance Schedule of a Steam Turbine Plant.
(A Case Study of Egbin Thermal Power Station)

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.
