Starter Motor Sizing For Large Gas Turbine (Single-Shaft) Driven LNG Strings.
Abstract
The purpose of this paper is to describe how computer
simulation was used to size the main starter motors for single shaft
gas turbine driven compressor strings used in a large LNG plant.
The paper describes how the components of the system were
modelled and discusses assumptions used in the calculations. The
paper presents the actual computer output plots showing the
predicted torque loading on the motor and the contributions of each
of the components in the string to this predicted loading.
The simulation program was also used to predict the loading of
the motor during a full load test at the compressor vendor's facility.
A torquemeter was used to measure the output of the motor during
the string acceleration. The paper presents the results of the
simulation prediction for the test runs and correlates the actual test
measurements to the prediction.
