Use of an Electronic Model To Evaluate Control Concepts for a Regenerative Gas Turbine 630300

Introduction of the exhaust heat exchanger and variable geometry turbine add to the complexity of the gas turbine control problem, necessitating the use of analog simulation methods for control analysis. Simulation from basic thermodynamic equations results in excessive analog equipment requirements and loss of accuracy because of the large number of algebraic operations. This paper describes a simplified method that makes maximum use of steady-state data obtainable from a digital computer program. Comparison of equipment requirements and cost of conducting a typical study by two methods of simulation are presented.
