Software for Fuel Schedule Selection and Transient Behaviour of Marine Gas Turbine

Abstract

A software package has been developed to predict the transient behaviour of marine gas turbines accurately and methodically to provide suitable data for design of fuel controller. Limits of fuel scheduling were established initially. This was done with the help of an independent module made to provide a graphical tool for fuel path selection which is an iterative process and has direct effect on dynamic behaviour of the plant. After independent trails a set of four paths were selected. Transient behaviour of the gas turbine was studied based on these four fuel paths. It is found that this package provides accurate and adequate information for design of analog or linear fuel controller. It is also noted that if an error of about 10 per cent is tolerated, then data obtained from this package is equally suitable for digital fuel controller design.
