Effect of Planned Preventive Maintenance Application on the Performance of Egbin Thermal Power Station

Abstract

This paper surveys the performance of gas-turbine plants in Egbin Thermal Power Station and evaluate the effect of planned preventive maintenance on the performance of egbin thermal power station.Today’s economic climate requires that industries aims at achieving maximum production capability, while minimizing capital investment through quality and routine maintenance structure. Performance assessment was embarked upon to analyze the current situation of the power station. Overall equipment effectiveness model (OEE) approach which comprises of availability rate, performance rate, and quality rate, was used to carry out this work. The investigation revealed that among the five years duration used for this study 2005 has the maximum average availability rate, performance rate and quality rate of 95%, 87% and 81% respectively, which indicate that impact of maintenance policies was encouraging at that year. Further studies show that the low rate of the subsequent years was caused by the shutdown of unit-6 due to shaft bending.
