Integrated gasification combined cycle (IGCC-Integrated Gasification Combined Cycle) is quite promising clean coal technology , advanced power systems , has made ??significant development in the overall technology . However, some of the technology is not yet fully mature , the IGCC system than the investment cost and the cost of power generation is relatively high , and the available rate of less than ideal , still can not be used as a powerful clean coal power generation technology is already quite mature , evolving pulverized coal steam power plants compete with a lot of room for improvement in the the optimized operational aspects of the system . And for system simulation assumed conditions in the design , in fact , due to changes in atmospheric conditions , load fluctuations , as well as system conditions change , the IGCC system in more variable conditions state . This article this article to a proposed 200MW IGCC system for domestic construction , for example , in the simulation the integration model development platform IMMS prepared with FORTAN language simulation program , the establishment of a system of major equipment model , including air separation model , gasification model of furnace systems , gas turbine model model of waste heat boiler , steam turbine model , as well as auxiliary net model , workflow based system , each part to be integrated , to study the dynamic operating characteristics of various variable working conditions for dynamic simulation test , draw the response curve of the important equipment performance parameters of each device , and draws some valuable conclusions , and provides an important technical means for the IGCC unit performance analysis and optimization as well as the actual operation . Test results trend consistent with the literature , show that the mathematical model is accurate and reliable , the simulation model has strong stability and practicality to provide theoretical basis and reference value recommended the IGCC system running control .
