EMTPWorks Open Architecture
  • EMTPWorks has a 3-Layer design. The lowest is a framework for the actual interface code. A second layer is added for supporting scripting methods. The third layer is the user or developer access layer. It provides a large collection of scripts for modifying and/or updating almost anything appearing on the design canvas. The scripting language is JavaScript with added methods for communicating with the framework layer
  • All built-in devices are scripted for data and device symbol handling. Device symbols can be contextually updated through scripts. A device symbol editor is also available
  • Device data capture forms are based on DHTML. Powerful data forms are created using JavaScript, DHTML and ActiveX. Device data can reside anywhere on the web
  • User can create own devices and externally program the full data handling methods
  • In addition to device scripting, EMTPWorks provides full design scripting. Scripts are used to search for devices or to retrieve and modify data for a large number of devices using a few lines of script. Scripts can be also applied to signals
  • Scripts are also used to generate the static Netlist submitted to EMTP-RV
  • EMTPWorks provides unsurpassed customization options and can be easily converted and used for other applications in power system analysis

Device library
The devices are created and maintained in EMTPWorks and transmitted to EMTP-RV in the Netlist file. There are built-in devices, built-in encapsulated devices and user-defined devices. Built-in devices are the fundamental ones supported by the EMTP-RV code. Encapsulated devices are devices created in EMTPWorks by interconnecting built-in devices. User-defined devices may be created by using various techniques for data hiding and encapsulation or by providing complete device codes through DLL's.

TDevices are found in EMTPWorks libraries which will be continuously updated. The first commercial version of EMTP-RV will contain the following libraries:

Pseudo device: Signal interconnections devices all built-in.
  • RLC branches:
    • Built-in devices: single or three-phase RLC's, single/three or multi-phase PI sections, single/three or multi-phase coupled RL and multi-phase FDB branches.
