Training Simulator


System operators and engineers must have instant access to online information and analysis tools that allow them to predict an outcome before system actions are taken. The ability to simulate the sequence-of-operation using real-time data is of fundamental importance. Real-time simulation can avoid inadvertent plant outages caused by human error, equipment overload, etc.

Real-time simulation provides an environment that is effective for operator training and assistance. Compared to traditional training methods, operator training is accelerated using dynamic graphical simulation of the power system. This makes training an ongoing process.

With Predictive Simulation, not only can you perform analysis using real-time system parameters, you can also simulate “what if” scenarios simply by taking action using the online system model. For example, using real-time data, the engineers can simulate the impact of starting a large motor without actually starting the motor. With minimal training, system operators can learn to use this valuable tool.
