【 摘 要 】

The goal of this DOE Vision-21 project work scope is to develop an integrated suite of software tools that can be used to simulate and visualize advanced plant concepts. Existing process simulation software does not meet the DOE's objective of ''virtual simulation'' which is needed to evaluate complex cycles. The overall intent of the DOE is to improve predictive tools for cycle analysis, and to improve the component models that are used in turn to simulate the cycle. Advanced component models are available; however, a generic coupling capability that will link the advanced component models to the cycle simulation software remains to be developed. In the current project, the coupling of the cycle analysis and cycle component simulation software will be based on an existing suite of programs. The challenge is to develop a general-purpose software and communications link between the cycle analysis software Aspen Plus{reg_sign} (marketed by Aspen Technology, Inc.), and specialized component modeling packages, as exemplified by industrial proprietary codes (utilized by ALSTOM Power Inc.) and the FLUENT{trademark} CFD code (provided by Fluent Inc). ALSTOM Power has a task responsibility to select and run a combined cycle test case (designated as Demonstration Case 2) to demonstrate the feasibility of the linkage concept. This report summarizes and documents the unit selected to represent Case 2, a 250 MW, natural gas-fired, combined cycle power plant. An analogous document for Demonstration Case 1 was previously submitted on April 30, 2001. Sufficient information is available from the plant to adequately benchmark the model. Hence, the proposed unit is deemed to be well suited as a demonstration case. However, as the combined cycle plant selected for this study contains recent technology, sensitivity to the commercial implications of this study prevents the release of the plant name and limits the quantity of operating/design information that can be presented. These limitations will not prevent the goal of this task, demonstration of the feasibility of software integration for ''virtual simulation'', from being accomplished.
