A new resource is available to explain step-by-step how to create a DLL in EMTP.776

Abstract
A new step-by-step resource is available to explain how to create a DLL in EMTP®.

The DLL (Dynamic Link Library) function is designed to allow EMTP® users to develop advanced program mode... see morel modules and interface them directly and intimately with the EMTP® engine. It is for advanced users and offers advanced capabilities.

Users interested in programming language-based model development should use this feature to develop and maintain models. Such models can be placed in a specified location, attached to a device with graphical user interface features in EMTPWorks and maintained in a library just as any other built-in EMTP model.

This option may be used by converter manufacturers to interface real code into EMTP®, to perform Software In the Loop.

For this purpose, EMTP® is also compatible with the Joint IEEE TASS Task Force and CIGRE B4.82 Working Group “USE OF REAL-CODE IN EMT MODELS FOR POWER SYSTEM ANALYSIS”.

Inclusion of a White-Box Transformer Model in EMTP746

Such white-box models could also be utilized in general transient simulation studies. This presentation describes the inclusion of one white-box model in EMTP using DLL code. The resulting model is highly efficient and it can be used to study internal overvoltages in the transformer during network transients, e.g. swithing operations and lightning strokes. The visualization of internal voltages is achieved by a matlab-based tool.
