The first step in model development is the selection and positioning of ProTRAX modules to represent the actual plant configuration. These modules are chosen from the extensive ProTRAX module library. Each module corresponds to a plant component, such as a pump, valve, boiler, turbine, etc. The component icons are simply dragged and dropped onto the model-building screen, and then connected to one another. The resulting schematic, essentially the same as the plant P&IDs, defines the overall model configuration.
After positioning and connecting the modules, each one is tailored to the specific plant or process by entering component-specific physical and operating point data into the ProTRAX database. For example, if you select a superheater module you will be prompted to enter tube dimensions, metal masses, and flow configuration using fill-in-the-blank forms. From this data the coefficients reflecting the operation of that specific component are calculated and written into the model. The resulting plant-specific model can then be copied onto any compatible computer for engineering analysis or operator training.
