Generic Combined Cycle (GCC) Simulator
Full-scope training simulator for operational plant theory and training.
The GCC simulator is a full scope replica of a 1X1X1 CCGT power plant that utilizes natural gas to feed a gas turbine generator, a heat recovery steam generator system, with low NOx duct burners and a condensing reheat steam turbine generator.
The GCC simulator includes a real-time high-fidelity JTopmeret model of multiple plant systems, a JElectric electrical distribution and generator model with auto sync and voltage regulation, a robust JControl simulated distributed control system (DCS), and a custom JDesigner Human Machine Interface (HMI) complete with an audible alarm system.
GSE full-scope simulators are powerful tools for exploring power plant theory and operational training. They are often adopted as part of research and education programs at universities and labs worldwide. The GCC simulator is also suited to research involving human factors, control optimization, and power plant cyber security.
The GCC simulator is created using only in-house GSE software and licensing, making it easy for users to create multi-student classrooms using the same simulation model or hosting online via the cloud for easy and maintenance-free access.
Key Features
Reference PIDs
The GCC model includes the reference PIDs/JTopmeret drawings used to model each of the plant systems. This gives operators transparency as to the current state of the model, where valves, transmitters, and plant equipment are located and how each system interfaces with one another.
HMI Graphics Display
The HMI is created using a custom library of icons using GSE’s JDesigner and JEditor software. The Graphics displays along with control group, faceplate, trend displays and audible alarm system provide operators with control and monitoring capabilities of a fully functional CCGT plant.
JStation
GSE’s JStation allows the instructor to manipulate, control, monitor and evaluate the simulator during training sessions, including run/freeze the simulator, snap and reset Initial conditions, backtrack to previous simulator conditions, implement remote functions, malfunctions, global component failures, and trend and monitor model variables and parameters throughout the simulator.
Self-Paced Procedure Training (SPPT)
The GCC simulator includes 10 pre-configured, self-paced training plant procedures. Exercises include multiple system-specific start-up procedures that walk the operator through setting the plant up for a GTG start, rolling the GTG, lining up the HRSG for steam production, and rolling the STG from cold conditions to full load with duct burners.
GCC Simulator Value
The GCC simulator is a great tool for users who want high-fidelity training on CCGT plant systems and operations are not in the market for a custom full-scope simulator or need to distribute training to a diverse workforce. With SPPT, individuals can effectively train on the simulator without the need for an instructor present.
- Very cost-effective compared to custom simulators
- Web-hosted solution eliminates IT and maintenance headaches
- A high-fidelity plant model provides realistic feedback
- Train on plant procedures, cause and effect scenarios, and troubleshooting skills
- Self-Paced Procedure Training enables individual use of the simulator
- Improve situation awareness by practicing a wide variety of potential plant events
- Useful platform for research into human factors, control optimization, and plant cyber security threats
HIGH-FIDELITY MODELS
The GCC is modeled using GSE’s thermal-hydraulic engineering tool, JTopmeret. JTopmeret is a graphical user interface that assists in developing two-phase, multi-component, non-thermal equilibrium, high-fidelity plant systems models.
