Full scope power plant simulators

The superior training environments of our simulators provide clear advantages for operator licensing, optimizing plant operating procedures and reducing costs. Operators trained in L-3 MAPPS simulator environments gain the skills necessary to increase plant performance, minimize downtime, and provide confident emergency response. Simulator uses include interactive team training, severe incident management, and plant design testing and startup/shutdown optimization.

L-3 MAPPS’ replica-quality hardware controls and touch-screen virtual panels create realistic, credible control environments. Real-time response to operator actions, and interactive instructor control ensure maximum training effectiveness and adaptability. Any scenario, no matter how complex or dangerous in a real plant, can be repeated, monitored and varied in real-time, providing a valuable tool for training and plant engineering.

Our commitment to customer support extends far beyond industry norms. L-3 MAPPS’ unique knowledge transfer program allows customers to gain expertise in the software and total confidence in the simulator. Users can directly implement simulator modifications to exactly reflect plant changes, evolve their training programs and expand simulator use into other areas.
