About the importance of simulation
Considerations aboutConsiderations aboutrealreal--time simulationstime simulations
Let’s consider the design of an aircraft.
Cost Billions$ to design and manufacture.
Can we wait until the first flight test to verify it actually fly?
Consider now a large power gridg p g
Again, it can cost $billions to design
Can we wait until commissioning to make sureit is stable and robust?

Impact of Real Time Digital Impact of Real Time Digital Simulation TechniquesSimulation Techniques
Real time digital simulation• represents an important advancement in the understanding
f t ti d f of power system operation and performance • allows more organizations to establish affordable and
manageable in-house simulation facilities• combines the accuracy of digital models with the real time
response of traditional analogue simulators• provides a mechanism to rigorously study and test the
performance of new and existing protection and control devices prior to installation in the actual power system
The World Standard for Real Time Digital Power System Simulation
devices prior to installation in the actual power system • provides detailed knowledge of power system performance
before, during, and after an event• increases confidence and reliability in the design,
implementation and operation of the electrical network and its complex components
