EMTP-RT seamlessly integrates a number of key eMegasim features into EMTPWorks, the modelling environment of EMTP-RV.
Opal-RT Technologies has released EMTP-RT, software interface which brings the real-time simulation power of Opal-RT's eMegasim real-time digital power grid simulator to EMTP-RV EMTP-RV is electromagnetic transient simulation software designed for utilities and research centres worldwide
EMTP-RT seamlessly integrates a number of key eMegasim features into EMTPWorks, the modelling environment of EMTP-RV.
These include real-time simulation capabilities, integration with both Simulink/SimPowerSystems from The Mathworks and Opal-RT's RT-Events blockset and the ability to separate design models for execution on multiple multicore CPUs.
Engineers and operators now have the option to conduct simulation of EMTP-RV models in real-time without the need to migrate to an unfamiliar simulation front end.
"Simulation of electromagnetic transient phenomena has always been required to ensure safe and efficient power grid operation".
"However, conducting real-time simulation of power grids from EMTP-RV system data has always been a very time consuming task", said Jean Mahseredjian, Professor of Electrical Engineering at Ecole Polytechnique de Montreal and EMTP-RV Technical Leader.
"With the tools like Opal-RT's EMTP-RT, electrical engineers can now efficiently conduct a wider range of simulation studies, in real-time, without the need to re-enter and re-validate all system data used with EMTP-RV off-line studies".
"EMTP-RV represents one of the most open approaches to offline simulation available in the power industry today".
EMTP-RT supports most EMTP-RV models and features, and is designed to be easy to use by both electrical engineers and simulator operators.
Once EMTP-RT has been deployed, it can be enabled with a simple mouse click.
Users can conduct standard offline simulations using the EMTP-RV solver or transfer their design data automatically into the eMegasim real-time world.
This EMTP-RV to real-time process, which includes data transfer and data conversion, can be executed automatically within minutes, without the need for user intervention.
EMTP-RT also imports EMTP-RV load-flow and steady-state simulation results to initialise machines and control states during real-time simulation.
EMTP-RT reads a specialised Netlist and imports complete circuit data into the eMegasim environment, which integrates Simulink and SimPowerSystems from The Mathworks, as well as RT-Events and Artemis, real-time Simulink libraries developed by Opal-RT.
Models are imported into eMegasim as .mdl Simulink files.
However, this remains transparent to the user during the conversion process, due to EMTP-RT's tight integration into EMTPWorks.
While EMTP-RV and SimPowerSystems models share many similar characteristics, data that is entered by the user, calculated and sent to models often differs between the two environments.
To overcome these differences, EMTP-RT applies several model transformations, allowing data imported from EMTP-RV models to be used with a high degree of accuracy in a SimPowerSystems environment.
EMTP-RT is also a useful tool for SimPowerSystems users who wish to simulate EMTP-RV-based models in a SimPowerSystems environment.
Within seconds, EMTP-RT converts EMTP design data into a SimPowerSystems model format.
This feature helps engineers save up to several days of manual conversion for each model.
EMTP-RT is now available from Opal-RT and the company's global network of distributors.
