Abstract
This paper describes a modified modeling and simulation of the measurement and control system of the single shaft Gas Turbine (GT). This GT is used in electrical power generation in Khalda Petroleum Company. The main objective of this paper is to obtain a multi-purpose controller modeling and simulation that can be used in future testing. This controller controls the GT under heavy disturbance; considering the monitored variable is the mechanical torque. That is to obtain a general GT controller which can drive either a compressor or a generator. Then a testing procedure is done to test the Electronic Gas Turbine Control Unit (EGTCU). The system response and stability are considered to modify controller parameters and validate the controller before installation in real gas turbine system.
