Part Load Stability Analysis of a Gas Turbine

Abstract

Majority of the Gas Turbines are designed to operate at their rated power output conditions, typically referred as base load conditions. The performance of a gas turbine at part load may vary from its base load performance. The purpose of this study is to analyze stability of Gas Turbines under part load conditions. This study involves a stability analysis of control strategies during part load operation and proposes control actions that can enhance performance. As a part of this study, analysis of field data will be done first to observe the performance/stability of controls strategies. A simulation will be setup to replicate the site behaviour and will be used to perform root cause analysis. Once the cause, if any, is understood, feasible solutions will be explored and implemented in simulation environment. The complete process will also be documented in detail.
