TRAX builds simulator process models using the ProTRAX simulation software. Each plant-specific simulator is configured to exactly match the simulated plant, and the individual components of a model are tailored to the specific plant, resulting in a simulator that truly represents plant operation. The process models generally include the main thermo-hydraulic processes, as well as associated electrical buses and auxiliaries as required for the specific operation of the plant.
TRAX specializes in providing high-fidelity, engineering-grade models. To be a “high-fidelity” model, three items must be true:
- Equations describing component behavior are based on conservation of mass, energy, and momentum (first principles) along with well-accepted constitutive equations for heat transfer and flow.
- The plant model accurately represents the configuration of the actual plant.
- Each component’s parameters accurately represent the corresponding component in the actual plant.
In addition to our high-fidelity modeling, we also work with our customers to identify the parts of the process that can be adequately modeled using simplified modeling. This enables TRAX to provide a cost-effective simulation solution, customized to the project requirements, that will provide excellent training value.
The most common type of simulator is a virtual system. In a this type of system, TRAX exactly duplicates the controls in the plant using the DCS supplier’s virtual control system. The plant files are downloaded to the simulator with no manipulation, translation, or special interfaces required. With this configuration, the control logic executes on a standard computer instead of the hardware controller used in the plant, resulting in the exact same functionality.
TRAX also offers emulated simulators. TRAX’s fully emulated systems use a translation of the plant control logic and graphics into the simulator environment. This translation is sometimes performed with an automatic translation program, and sometimes TRAX will manually build the control logic in ProTRAX.
