GRU's Kelly 120 MW simulator includes gas combustion turbine, HRSG, steam turbine generator, and controls.
Gainesville Regional Utilities Installs TRAX Simulator at J.R. Kelly Generating Station
In Q1 2023, TRAX delivered a combined cycle plant simulator to Gainesville Regional Utilities (GRU) for the J.R. Kelly Generating station. The high-fidelity simulator 'provides a realistic and accurate representation of the plant, allowing operators to practice the startup procedure, normal operations, and simulated malfunctions in a controlled environment' according to GRU. A computer simulation system can provide an effective foundation for ongoing operator training as well as qualifying new operators.

Combined Cycle Simulation
The Kelly simulation includes a gas combustion turbine (GT), a heat recovery steam generator (HRSG), and Siemens steam turbine (ST) generator and controls. The maximum unit load is 120 megawatts (MW). TRAX performed the modeling using our proprietary simulation system, ProTRAX. ProTRAX system modules were used to generate the overall plant simulator schematics. The GT model was coupled with a HRSG model to provide training focused on the HRSG steam cycle. This simulator also included a virtual control system for the ABB controls and HMI stations.
'...the simulator is an investment in the education of new employees as senior staff retires and significantly speeds up the training process for operators. It enables them to make mistakes, build habits, and learn how to respond effectively in various scenarios. The motto displayed on the simulator's door, 'Practice until you can't get it wrong,' perfectly captures the purpose of this tool.¡±

The Kelly simulator allows operators to practice in widely varying conditions. Operator training can include startup, shutdown, load maneuvering, rundown/runback, and trip scenarios.
Simulators are especially useful for practicing operating conditions that may occur less frequently on the running unit. Operators can train and retrain on any condition instantly using a simulator. This simulation training prepares operators to respond in the safest, most efficient manner to even rare conditions. Critically, operators can safely experience emergency conditions and practice a response.
TRAX would sincerely like to thank the Kelly simulator team for a great project. This is TRAX¡¯s second simulator with GRU, following delivery of a simulator for the Deerhaven plant.
