| Summary: | The objective of this research was to compute reliability of three diesel engine generator
systems at a power plant using Fault Tree Analysis approach. The diesel engine systems
had been operated since installed in January 1995 with initial capacity of 8.16 MW.
However, their load capacity at the end of December 2009 was 6.0 MW for diesel
engine generator sets 1 and 2, while 5.0 MW for set 3. This means that their reliability
performance had decreased. The Fault Tree Analysis was used to investigate the causes
of decreasing reliability. Fault Tree Analysis was not a common tool for evaluating
reliability. To enable the use of Fault Tree Analysis for reliability analysis, the fault tree
was converted into Reliability Block Diagram. A power plant was said to be reliability
when it has 99.99% performance reliability. The three diesel engine generator systems
were evaluated using reliability analysis and compared to the 99.99% of performance.
Results of the reliability analysis indicate that two out of three diesel engine generators
not meeting the reliability standard. The root cause of this problem was due to sub
systems of the diesel engines had high frequency of failure occurrence which led to low
reliability |
