Project Input. Flexible Inputs. Version 7.0

Transcription

1 Project Input Version 7.0 Flexible Inputs SOAPP CT provides worksheets for you to specify your input for each of the four data sets that define a specific project and conceptual design. This worksheet format allows you to copy and paste inputs directly into SOAPP CT from other sources, such as a spreadsheet you might set up to model some of your key assumptions. Fifteen input arrays allow you to specify your own models of critical project assumptions, such as the behavior of contract or market rates for fuel, energy charges, capacity charges, etc. over time. You can choose to define these models with a full set of discrete values or simply specify a starting value and average escalation rate for any number of periods and SOAPP CT will generate values that meet these specifications. SOAPP CT will display plots to assist you in verifying the models you specify info@soapp.com

2 Project Input (continued) Version 7.0 Accurate Combustion Turbine Modeling Select one of the 100 combustion turbines modeled from data supplied to SOAPP s specifications by manufacturers for specific turbines. Or, use SOAPP CT s Advanced Analysis feature to input the performance and emissions of any other combustion turbine you would like to evaluate. Intelligent Defaults Suggested input values are calculated based on current inputs. Input Validation Input values are validated for internal consistency. Values that are not feasible in the context of other inputs are highlighted in red. Project Validation Input values that cannot be validated out of the context of one or more of the other three data sets of project design criteria are shown in blue. These values are automatically validated before generating a plant design. Multiple Choice Selections Simplified specification of project design. View All Possible Inputs All possible inputs are always shown to speed consideration of options. Unneeded inputs are disabled ( grayed out ) consistent with current user inputs info@soapp.com
