Modeling And Performance Analysis Of Gas Turbine Combined Cycle System

In this paper, the development actuality and spectacle of the gas turbine combined cycle is introduced firstly. And meanwhile, the primary performance characteristic and construction characteristic of the GTCC system with its primary components are presented. Subsequently, utilizing the thought of modularization from system engineering, the GTCC system firstly is divided into 3 units which are gas turbine, heat recovery steam generator and steam turbine. And then, the performance models of these units are established in separate. Based on these units' models, the modeling of the GTCC system is achieved according to the production process. Finally, the software platform for performance evaluation of the GTCC system is established on the base of the Delphi software and above models. With this platform, the integrated performance of GTCC can be analyzed, consequently realizing the optimization of assembling methods of the GTCC system.
