Additional ATP Tools

ATPDraw has a standard Windows layout, allows several circuit windows and offers a large Windows help file system. From version 2.0 ATPDraw is written in Pascal in Borland Delphi 2.0 (32-bit for Windows 95/NT). In addition a version compiled in Delphi 1.0 (16-bit for Windows 3.1/95/NT) exists, but the development of this version stopped with the launching of ATPDraw 1.0 in July 1997. The ATPDraw package also includes the older ATP_LCC program for Line/Cable constant support and the utility Convert (to update old DOS files). ATPDraw requires moderate CPU power (Pentium, >90 MHz) and memory (~4MB).

ATPDraw is developed by Hans Kr. Hoidalen at SINTEF Energy Research in Trondheim, Norway, with Dahl Data Design as a programming sub-contractor. Bonneville Power Administration in Portland, Oregon has financed the program development, with Pacific Engineering Corporation as project coordinator.

- Developer:

Hans Kristian Hoidalen was born in Drangedal, Norway, in 1967. He received the M. S. degree in electrical engineering and the PhD degree (Lightning-induced overvoltages in low-voltage systems) from the Norwegian University of Science and Technology in 1990 and 1998, respectively. He is now an Associate Professor at the same university. (e-mail: hans.hoidalen@elkraft.ntnu.no)

ATP Control Center (ATPCC) is a user-shell for the ATP-EMTP versions, supporting programs ATPDraw, PCPlot, PlotXY and any other ATP related programs running under Microsoft Windows 95/98/NT/2000.

- Main Features of ATPCC:

• Working with two different ATP versions at the same time possible
• File type sensitive execution of ATP, ATPDraw, PCPlot and other programs. Double-click on file names or execute using context menu
• Working with any editor preferred by the user is allowed
• Up to 10 external programs can be linked to ATPCC and executed from the user shell
• Project based handling of simulation data cases
• Event window displays previously executed commands
• Re-execution of the preceding commands from event window

GTPPLOT is a plotting program for ATP output, compiled with the GNU FORTRAN, and makes use of the graphical package DISLIN. The program is available for DOS-djgpp extender, Windows 32, and Linux. It has the following capabilities and limitations.

- Main Features:

GTPPLOT can read widenn, formatted graphics files (FMTPL4 = 10Fnn.) both with nn arbitrary, C-like binary files, including the new format obtained with NEWPL4=2 (called PISA), with normal or double precision, and FORTRAN (DOS-djgpp, Mingw32, Linux, and SALFORD) unformatted files. The program detects automatically the format of the file. COMTRADE files (both ASCII and binary), and ADF (ASCII Data Files), can be read by GTPPLOT, too.

GTPPLOT can process graphics files with up to 1000000 points and up to 1000 variables, sufficient for the usual application.

The program can plot graphics with 1 to 20 curves. The curves can be distinguished by color, linetype or symbols, or the combinations of them. For FS and HFS the plot can be bar charts.

The program does not sense the mouse. The user must use the keyboard for all the input operations.

The program can generate graphics files in nine different formats: HP-GL (Hewlett-Packard Graphic Language), CGM (Computer Graphics Metafile), WMF (Windows Meta File), PCX, PostScript, PNG (Portable Network Graphics), WMF (Windows MetaFiles), JAVA and GNUPLOT. Some options are limited with GNUPLOT format.

The data can be exported as widenn pl4, as COMTRADE (ASCII and binary), Matlab, MathCad and Mathematica files.

The screen plot can be in various formats, in color or black and white, and the screen resolutions supported are 640*480, 800*600, and 1024*768. The Mingw32 and Linux versions use the screen resolution as defined by the operating system.

Furthermore, the program calculates a lot of PQI from data, as FOURIER analysis, turbine shaft loss of life estimation, Bode plots, plot of ARMAFIT output, impedance calculation, generation of sources for HFS, and various simple math operations with variables, as integration, derivation, RMS, power, energy, I2T. The program searches for extrema, zeroes and peaks of variables. The GTPPLOT can help to generate KIZILCAY F-DEPENDENT elements from FREQUENCY SCAN pl4 files.

The GTPPLOT can produce plots with different pl4 files, or create a pl4 file with variables of different pl4 files.

The program is easily installed copying all the files in the same directory, included in the PATH definition.

- Software/Hardware Requirements:

DOS version:
The CWSDPMI.EXE program is the memory manager and must be in the path. The current dimension requires no disk paging with 16 Mbytes of RAM or more. A good disk cache is recommended. The DOS version is limited to 100000 time points.

WINDOWS 95/98/NT/2000 and Linux versions:
These versions require only to copy the package to a directory included in the path. For Linux, /usr/local/bin is a good location.

- Available from (password required):

All password protected ATP related sites can make GTPPLOT available.

PlotXY is a WIN32 plotting program originally designed for use with ATP/EMTP, but now able to work satisfactorily also with ASCII data files. The program is mainly designed to make, as easy and fast as possible, line plots in Microsoft Windows environments. It is also able to perform some post-processing on the plotted curves: algebraic operations, computation of the Fourier series coefficients.

- General characteristics:

• easy-to use Graphical User Interface
• full 32 bit (win32) code for very fast operation
• up to 3 files can be simultaneously held in memory for easy comparison of different data
• no limit in number of plot variables and data points

- Main features of the line-plots produced:

• up to 8 curves per plot
• plots from up to 3 different files on the same sheet
• plots versus time as well as X-Y plots allowed
• factors and offsets and zoom support
• possibility to make plots with two independent vertical axes.
• clever automatic axis scaling
• cursor to see values in numerical format
• plot export as Windows Metafile via win32 clipboard

- Main features of Fourier series coefficients display

• coefficients shown in graphical (bar charts) as well as numerical form
• amplitude and phase bar charts with sizes under user control
• time extrema of the considered period and number of harmonics on the bar charts under user control

WPCPlot is a graphical output program for ATP-EMTP running under Microsoft Windows 95/98/NT/2000. Present version 1.0 for Windows 95/98/NT/2000 is capable of processing plot files (PL4) of C-like type as well as of FORMATTED type generated by any ATP-EMTP version generally.

- Main features:

• Maximum 6 variables in the same diagram
• Curve and background colors are fully adjustable
• Readout facility to obtain instantaneous values of plotted curves
• Zooming, redraw features
• Copy plot area to clipboard
• Save image as color or monochrome BMP (bitmap) file
• Curve identifiers for monochrome BMP format
• Integrated help function
