Why Real-Time and Faster than Real-time Simulation?

Use of Modeling and Simulation at every step of the design: MODEL-BASED DESIGN

Why Fast off-line simulationwith parallel computers Fast user interaction

Feasibility and concept analysis

Design optimization of large systems

Statistical / Monte Carlo analysis

Why Real-Time (RT)? Connection to real physical equipment

Fast user interaction for debugging, tuning, optimizing, training …

Integration tests: functionality, performance, reliability, and safety

Applications of Real-Time Simulation : Full digital simulation for Software-In-The-Loop (SIL)

Rapid Control Prototyping (RCP) with physical or virtual plants

BETTER AND MORE TESTS IN SHORTER TIME


EMTP-RV real-time interface

4/30/2009 8

Project goal• Provide to existing Opal-RT users a better interface for large and very large topologies

• Provide to existing EMTP-RV users a real-time interface in EMTPWorks

Requirements

1) Develop a data translator:

from EMTP-RV data to

Simulink/SimPowerSystems data

2) Enable model separation tools

in EMTPWorks (distributed simulation)

3) Add to EMTPWorks special

real-time libraries. (Signal acquisition,

communication with IOs, special

models for real-time, etc…)

(Report Script

With EMTPWorks scripting tools, it is possible to customize the modeling

environment without any “hard-code” change


Custom Netlist generation

4/30/2009 10

• The EMTP-RV Netlist contains only the data required by its

computational engine (solver)

• Netlist generation rules can be modified by users (see C:\Program Files\EMTPWorks\Report Scripts\EMTP \Netlist.rfm)

• The Netlist generation script is called the Report Script

Language.

• We modified the Netlist to provide to the data converter the

missing elements (device position, orientation, subsystem-

device (ex: transformer, etc…)

Model separation for real-time – right click on any power line

Automatically, the network topology is divided into 2 parts

Power systems can be separated on lines and signals

Control systems can be separated on signals

Separation can also be performed in subsystems

Conclusions

4/30/2009 20

EMTPWorks is an highly customizable tool.

With dwj scripts, circuit separation and validation tools were

developed

A new augmented Netlist for data exchange was created using

Report Script Language

HTML for new block panels and for SimPowerSystems machines

initialization

Most of EMTP-RV models and functionalities can be translated in

Simulink/SimPowerSystems

The EMTP-RV real-time interface is now commercialized
