Abstract
Heat Recovery Steam Generator (HRSG) adalah salah satu
komponen dari pembangkit listrik dengan prinsip kerja combined cycle
yang digunakan pada Pusat Listrik Tenaga Gas dan Uap (PLTGU).
HRSG menggunakan dua turbin yaitu turbin gas dan turbin uap.
Permasalahan yang sering terjadi adalah adanya kegagalan pada tubetube
HRSG. Hal ini dapat menyebabkan pada penurunan efisiensi dari
HRSG. Untuk mengetahui kegagalan yang terjadi, maka dilakukan
analisis dengan mendeskripsikan model kegagalan pada HRSG
menggunakan metode Fuzzy Fault Tree Analysis (FFTA). FFTA
merupakan salah satu metode analisis keandalan yang digunakan untuk
memodelkan kegagalan dari suatu peralatan. Hasil dari analisis FFTA
ini berupa nilai keandalan dan interval keandalan dari masing-masing
peralatan yang mampu menangani ketidakpastian yang sebelumnya sulit
diselesaikan dengan teori probabilistik konvensional. Berdasarkan
analisis FFTA yang telah dilakukan terdapat 3 peralatan yang
mempunyai nilai keandalan sangat rendah yaitu, LP Economizer 1.2
mempunyai nilai keandalan 0,45974 dengan interval keandalan
0,405718 dan 0,51377. HP Economizer 1.2 mempunyai nilai keandalan
0,45974 dengan interval keandalan 0,405718 dan 0,51377. Dan LP
Boiler Feed Pump 3A mempunyai nilai keandalan 0,517013 dengan
interval keandalan 0,468714 dan 0,521843.
====================================================================================
Heat Recovery Steam Generator (HRSG) is one component of
the power plant with the principle on the combined cycle used in steam
and gas power plants. HRSG use two turbines they are gas turbines and
steam turbine. The problem that often occurs is that there is a failure in
the HRSG tubes. This can lead to a decrease in the efficiency of the
HRSG. To know that failure occurs, then analyzed the failure of a model
describing the HRSG using Fuzzy Fault Tree Analysis (FFTA). FFTA is
one of the methods of analysis used to model the reliability of an
equipment failure. The results of the analysis is value FFTA interval
reliability of each piece of equipment that is capable of dealing with
imprecision and uncertainty which is difficult to be characterized by the
traditional probabilistic theory. Based on FFTA analysis has been
done, there are 3 equipments that has a very low value reliability. The
reliability LP economizer 1.2 is 0.45974 it has interval between
0.405718 and 0.51377, The reliability HP economizer 1.2 is 0.45974 it
has interval between 0.405718 and 0.51377, And The reliability Boiler
Feed Pump 3A LP is of 0.517013 it has interval between 0.468714 and
0.521843.
