Analisis Kinerja Turbin Gas MS7001EA

Abstract

Gas turbine is one of the main components in the natural gas liquefaction process which is used to drive the refrigeration compressors and its performance greatly affects the overall performance of the natural gas liquefaction process. Therefore, it is necessary to monitor the performance of the gas turbine to ensure that it is performing optimally and that the gas turbine is operating within the design limits. The objective of this research is to apply a method for gas turbine performance monitoring that includes thermodynamic performance and rotordinamic parameters. The thermodynamic performance of a gas turbine is calculated using the ideal thermodynamic cycle approach for gas turbines, Brayton cycle; while, the rotordynamic parameters are monitored through the vibration, rotor axial position, and bearing temperature of the gas turbine. This gas turbine thermodynamic performance monitoring method is applied using Microsoft® Excel® software for gas turbine MS7001EA. The data needed to calculate thermodynamic performance and to monitor rotordynamic parameters are obtained through the P2® Explorer software which is connected online to the instrumentation that installed on the gas turbine. This performance monitoring method has been successfully applied to the MS7001EA gas turbine so that it can obtain thermodynamic performance and rotordinamic parameters.
