EMTP-RV Installation Requirements
1. New models
New detailed Current Transformer (CT), Voltage Transformer (VT) and Capacitive Voltage Transformer (CVT) models are added to the «Transformers library» in both 1-phase and 3-phase versions. The models are based on IEEE and ANSI standards and include nonlinear properties (saturation).

2. EMTPWorks improvements
Bundles are easier than ever! It is now possible to connect directly into bundles without using breakouts. New options allow to create and modify connection pins and signals. The new «Bundle Connection» window make easier the connection and routing of bundles containing numerous signals. It helps the user to efficiently build complex multivariable control systems.

Other new features include:
3. FMI Toolbox
EMTP is now compatible with the Functional Mock-up Interface (FMI) standard.
The aim of the FMI is to standardize data exchange between different simulation tools.
The list of compatible tools is available on www.fmi-standard.org and includes :
- And others
EMTP is compatible with the FMI Standard for co-simulation as master (version 1.0 and version 2.0) and as slave (version 2.0). It is an easy to use interface between prototyping tools like Matlab/Simulink® or Modelica® and EMTP which let you benefit from the best of each environment.

4. New additional Toolboxes (require specific licence)
This new toolbox opens new doors for the simulation and analysis of protection systems. Both steady-state and time-domain simulation options are available. All relay, fuse and thermal element models are solved in time-domain with nonlinear functions, such as CT, VT and CVT magnetization. This new implementation for EMTP allows to achieve highest levels of accuracy for protection coordination and analysis of performance with highly accurate power system models.
The power system may include many details ranging from power electronics models, HVDC transmission models and wind generation combined with traditional generation and transmission. There are no limitations! The relays can capture transients, harmonics, and various effects from power electronics based device controls.
Setting protection systems for renewable energies is finally made easy with the new EMTP Protection Toolbox. The user can study any power system including inverted based devices for coordinating power-swing detection, distance protections, the interruption of currents by current-limiting fuses or determination of transformer differential protection settings.
Exciters and Governors Library
This new Exciters and Governors library contains 30 standard models for governors, exciters and power system stabilizers. It includes various models from the IEEE Standard 421.5-2005 “IEEE Recommended Practice for Excitation System Models for Power System Models for Power System Stability Studies”:
• Exciters: AC1A, AC2A, AC3A, AC5A, AC6A, AC7B, AC8B, DC1A, DC2A, DC3A, IEEET5, SEXS, ST1, ST1A, ST2A, ST3A, ST4B
• Governors: DEGOV1, GAST, GAST2A, IEEEG1, IEEEG3, IEESGO, TGOV1
• Power System Stabilizer: PSS1A, PSS2B, PSS3B
• Excitation limiter: Over Excitation Limiter OEL1B, Under Excitation Limiter UEL1
The models are built to be easily interfaced with Synchronous machine models in EMTP.
Each device comes with its own user-interface, comprehensive documentation, and is automatically initialized from EMTP steady-state and load-flow solutions. The control diagram of each device is fully customizable. New exciter, governor and stabilizer models are being added continuously and will become available in the future releases of this toolbox.
The LIOV (Lightning-Induced OverVoltage) code allows the calculation of lightning induced overvoltages on multiconductor lines above a lossy soil as a function of the line geometry, lightning current waveshape, stroke location, return-stroke velocity and soil electrical parameters. In order to deal with distribution networks having complex, realistic topology and configuration, the LIOV code has been interfaced with the Electromagnetic Transient Program (EMTP).
The LIOV code has been validated by means of several experimental data, related to natural and triggered lightning experiments, and by means of Nuclear Electromagnetic Pulse Simulators and reduced scale models. The analysis of more complex system configurations composed by several lines and power components can be dealt with by using the LIOV-EMTP module.
The new Simulink® Toolbox allows to import any Simulink® models, regardless of its complexity, into EMTP designs using two clicks. Minimum intervention from the user is required and the procedure only takes few minutes!
Using the appropriate Matlab® / Simulink® toolboxes and a compiler, a DLL is automatically created and used by this import tool to create the EMTP model with all the necessary connections (pins). Vectors, complex and real signals can be interfaced with EMTP. It is also possible to define tunable parameters in the Simulink® model and to assign them in EMTP.
This Toolbox streamlines many complex tasks for building and exporting models built in Matlab / Simulink®. The Simulink® based models can be rapidly connected to complex EMTP networks and benefit from the available and unique computational performance and models for large scale power system simulations.
