Atp power system software

What is atpdraw?

ATPDraw is a graphical, mouse-driven preprocessor to the ATP version of the Electromagnetic Transients Program (EMTP) on the MS-Windows platform.

How do I install ATP & atpdraw?

In order to obtain the installation files from www.atpdraw.net, the user must first become licensed. The license application form can be found at www.eeug.org. The steps below will guide the reader through a manual setup of ATP and ATPDRAW. This setup was tested in Windows 10. The specific steps here are intended for new users.

Why is ATP important for protection engineering?

Using ATP, protection engineers can quickly calculate transmission line parameters from physical data; as well as investigate the impacts of CT saturation, transformer inrush, and other complex phenomena on protection system performance. Model validation is an important part of any transient simulation.

How to register atpdraw?

Users can register with email authentication by passing a CAPTCHA and an EMTP quiz. The web-site offers discussion forums with nested discussions, images/document uploads and search functionality. By registering on this web-site users also get access to latest ATPDraw downloads (NOT the solver tpbig.exe).

What updates are included in atpdraw 7.5?

The following updates are included in ATPDraw 7.5: Support of universal line model, ULM Foreign Model (Leal-De Conti-Zanon) v3.2. The model requires an updated solver available in the EEUG 2023 distribution. No steady-state initialization is available at this point. Frequency scan not possible.

Does atpdraw work for a line model with more than one circuit?

ATPDraw corrects this for CABLE PARAMETERS by removing the col 79 flag. Transpositions did not work in v7 for line models with more than one circuit. Very important fix. Minor: Num-key +/- works with mouse inside the sidebar without zooming. View window and its click on curve dialog centered.
