Research And Simulation Of Gas Turbine Control System Based On Decoupling Control

To the gas-steam combined cycle unit of Mitsubishi, research and analysis the control system of gas turbine which is the top equipment of unit in this paper. Begin with the control objectives and control task of gas turbine to research each subsystem. Proposed the control method about decoupling control of multivariable gas turbine system from the research in gas turbine control system. In the designing and optimization parameter of decoupling controller, using the intelligent decoupling method based on the DRNN and neuronal compensator. To the method, make the detailed theoretical study and simulation experiment. Realizing the algorithm of decoupling controller module in STAR-90 simulation platform, applied it to the actual simulator system of gas - steam combined cycle unit. Simulation results shows that the decoupling controller can achieve good control effect in control system of gas turbine.
