Resumo

Given the current scenario of economic, environmental, and energy security constraints, Integrated Gasification Combined Cycle (IGCC) power plants are among the most attractive options for power generation. As a consequence, IGCC plants have attracted the attention of several studies regarding their physical and economic characteristics. In particular, from a thermal system engineering viewpoint, due to the coupling of complex equipment such as gasifiers and gas turbines, it is important to consider accurately the effects of operational changes of one piece of equipment onto the others. In this context, this paper presents a software integration strategy to enable the detailed analysis of specific phenomena in each of the main components of an IGCC system, without losing sight of the power plant behavior as a whole. For the gasification process, the software CeSFaMBT has been selected, whereas the software NGGT is responsible for the gas turbine simulation. To interconnect the different equipment, include the other components related to the steam cycle, and perform the global system simulations, the professional process simulator IPSEpro has been chosen. It is shown through a simulation example, that the proposed software integration methodology results in a powerful platform for the analysis of complex engineering systems.
