Effect of failure rates on system reliability of a gas turbine power plant
Ac Aneke, Ao Odukwe, To Onah
Reliability of a Gas Turbine power plant is a function of failure rate, maintenance (scheduled or forced), which in turns depends upon the Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR) of equipment or systems, and which are further dependent on complexity in design, state, age of the equipment or system and to some extent on the availability of spare parts. This study tries to identify the vital component in the gas turbine power plant, establish the fact that failure rate inversely affects availability of gas turbine power plants, and thus, its reliability and also to use computer in timely evaluation of the actual figures of reliability, availability, failure rate, for any given power plant. It also assist thermal power plant managers establish a relationship between the types of maintenance adopted and plant reliability, and will also help in their day-to-day operating decisions. Observations from this analysis showed that increase in Failure Rate results in decrease in system reliability and availability. However, effective maintenance management is essential in reducing the adverse effect of equipment failure. This was done by accurately predicting the equipment failure such that appropriate actions can be planned and taken in order to minimize the impact of equipment failure on operation. Downtime losses and maintenance cost of a thermal power plant can be reduced by adopting a proper mix of maintenance and repair strategies on the failure rate of system reliability.
