Operator Training Simulator – eOTS™

Accelerate Dispatcher Operation Training

With increased focus on elimination of overdesign, system validation using digital twins, safety and emission compliance, as well as the realized saving through virtual readiness and preparation, the utilization of Operator Training Simulator has become a key factor in better design and improved operation of plants.

ETAP eOTS, model-driven Power System Training Simulator helps to improve and develop operator competency through real-world simulated learning.



From simulation to operation, eOTS utilizes the ETAP Digital Twin foundation to provide operators and engineering an effective learning environment to improve and augment their knowledge of the actual system.

  • Ensure operator readiness & foreplan contingencies
  • Increase operator competency & audit productivity
  • Improve system safety & security through real-world scenario simulations
  • Validate design using steady-state & dynamic simulation



Challenges & Concerns

Avoid Unplanned Outages Caused by Human Error

  • How to reduce risks associated with potential missteps in operator actions?
  • How to avoid mistakes caused by errors in switching plan sequence?


Reduce Start-up & Commission Times

  • How to ensure smooth and successful start-up and higher system availability?
  • How to reduce operational risk during the initial phase of production and system start-up?
  • Can the impact of the new facilities be simulated on the existing system before implementation?


Evaluate Operator Awareness & Readiness

  • Are the system dispatchers ready to response to malfunctions and emergencies?
  • How to prepare operation staff for unexpected situations and contingency scenarios?
  • How to effectively certify operators and confirm their readiness?



eOTS challenges the operators to become trained and knowledgeable about the behavior of the electrical power system and associated processes before facing the real-world operational situations. Through virtual simulation in response to operator actions contingences can be tested for normal and operations as well as emergency and abnormal conditions.

A model-driven power system training simulator to mimic the sequence-of-operation scenarios using real-time data to perform and validate actions such as configuration switching, generator synchronization, load shedding, , motor startup, and more.

eOTS allows a trainer to create preconfigured scenarios to simulate realistic situations on the electrical system while allowing the operator to respond to the disturbances.. The trainer has the capability to inject events, messages, and disturbances both electrical and non-electrical during the execution of the training to any or all operator stations.

Trainer has the capability of fully evaluating the steps by operators. On screen playback, step-by-step logs, alarms and control logs, and electrical system response evaluation at the fingertips of the trainer using real and simulated data in a trainer-trainee environment.

eOTS in a fully closed-looped system while simultaneously using Real-Time data using etap SIL™ - Software-in-the-Loop technology. It provides a training environment for operators that matches the operation of the power management system with dynamic response of the electrical system including its protection and control systems.

Key Features


ETAP Operator Training Simulator replicates a real-world system conditions and allows the trainees the opportunity to evaluate contingency responses to both steady-state and dynamic scenarios. eOTS uses actual system-operator interfaces with realistic learning simulations and logic schemes validation.
