ATPDraw latest version (7.6), Aug. 30, 2024

The following updates are included in ATPDraw 7.6:

  • Significant updates of UMSYN component.
    • Rotor type with full second order fitting similar to type 59.
    • Mechanical damping also in [pu]
  • Copy/paste of coil data from UMSYN (and UMIND) to UM_1, (and UM_3/UM_4).
  • Multi-mass component for universal machines (up 26 masses, flexible units).
  • Governor (hydro and thermal) and Exciter (ST1, AC1, DC1) controls for electrical machines. Exa_30 shows usage.
  • Updated Compress dialog. Data and Nodes are on separate tabs. Page number assignment to data allows multiple tabed data input. Useful for complex groups.
  • Bug fix and updates related to LCC_ sections in case of template swop.
  • Bug fix related to LCC Internal calculation at very high frequencies. Transposition now average diagonal elements and use analytical eigenspace for JMarti and ULM.
  • Bug fix for MODELS change inside Groups. Node/Data subscription no longer reset if Model instance is updated.
  • New examples Exa_29 for lightning study with ULM, and Exa_30 for the various controls with synchronous machines (SM, UM_1 and UMSYN).
  • Synchronous and universal machines in internal solver. No controls. Multi-mass component required for universal machines.
  • Updated User Manual.
  • Patch 1 updates
    • Introduces MoM-SO method for proximity effect calculation of pipe-type cable parameters. Very significant contribution, but also complicated. More research is needed on complex designs.
    • Corrects rare problems in bessel function library for large arguments.
    • Changes in linear algebra package for inverse of large complex matrices. Pivot problem correction.
  • Patch 2 updates
    • MoM-SO method implemented for complete (core-sheath-armor) pipe-type cables. Both capacitance and impedance.
    • BCTRAN has new option for winding resistance. As well as closed delta zero-sequence handling (by ATP).
    • XFMR has got core flux calculation and measurements included and an option for choosing the hysteresis loss portion with T96. Core settings.
    • New ATP|Line Phasor option. This reads steady-state phasor output (t=0) from the lis-file after the simulation and aligns it with LCC modules being selected, sorted by the x-position of the LCC objects. Current, voltage and power are then plotted as function of the position of the line and the phases involved. No restriction on the number of phases or the number of sections of the selected line. No need to add measurement switches for t=0 results. The feature can in the future be expanded into post time zero extraction, but this will require measurement switches and MODELS calculation.
    • Support to paste in data from external sources for standard components and LCC overhead lines. Standard component previously required Name=Data format, but now the Name part can be skipped. The LCC overhead line dialog has got two new Paste buttons (Replace, Append).
    • Line/cable pch import fix, both for Pi-equivalents and externally fitted ULM data. 

 

ATPDraw previous version (7.5), Nov. 20, 2023

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. The ULM model is a phase domain, frequency dependent transmission line model without a constant transformation matrix assumption based on the work by Morched-Gustavsen-Tartibi "A universal model for accurate calculation of electromagnetic transients on overhead lines and underground cables", TRPWD, 1999. It is the only model in ATP that will give correct induced voltages in a cable system. The ULM model in ATPDraw 7.5 is implemented in the LCC object and uses overhead line and cable parameter based internal calculations and Vector Fitting directly implemented in ATPDraw. Usage of the model is thus simple and equivalent to the other line/cable models supported. 
  • Updates in LCC Section
    • Dialog let the user control if Frequency and Ground Resistivity should be set or inherited from the Template.
    • Updates the template data if changed when the final ATP is created. Previously, a Template could be deleted and replace by another Template having the same name but different content without being noticed. Now, the section is forced to followed the named Template in the project.
  • Support of import of series impedance (Z) and shunt admittance (Y) matrices as function of frequency to the LCC object. The matrices can thus come from external sources like FEM software. Internal scaling with length and fitting to PI, Bergeron, JMarti and ULM is supported.
  • Multi-run improvements. The missing LIS-file observed in some extensive multi-run cases seems to originate from system overloading. The new version slows down GUI updates while running the simulation, and this seems to improve the situation. Failed simulations are reported at the end of the log-file (not new in v7.5).
  • XML-project file error related to variables corrected. CapAngle loaded.
  • Internal solver. A limited internal transient solver with steady-state initialization and frequency scan available. Press Ctrl-key when running the simulation to activate.
    • Supports around 70 components, but no controls, machines and BCTRAN/XFRM.
    • Uses nodal admittance matrix formulation based on trapezoidal rule of integration. Voltage sources and switches modeled by augmentation.
    • Sparse system matrix with partial LU factorization. No limits on size.
    • Object oriented data structure enables simpler future expansions.
    • Uses interpolation for switching and segment change events in the core of the timestep loop. Potential robust handling of power electronics and pseudo nonlinearities.
    • Supports ULM with steady-state initialization and frequency scan.
    • Creates a debug window with all plots and simulation times, but also a pl4 file.
  • New User Manual updated to cover new features, espcially in line/cable modeling.
  • Patch 1 fixes
    • SWIT_3XT error in Solver
    • Number of cables in LCC was disabled. Works on Data page only.
  • Patch 2 fixes
    • LCC Pipe data was not properly stored in v7.5 (pipe data moved to cable data page).
    • PI_CAB3S component was not written to ATP-file unless copies (wrong initial type).
    • Internal solver plot window updated with context menu and cursor.
  • Patch 3 fixes
    • Harmonic source (HFS_SOUR) access violation error
    • Clarke transform (ABC2xyz) sign error in beta-component
    • New differential relay (W1RELAY87TT) for 3-winding transformer, instantaneous type according to Gajic.
    • Internal Solver has JMarti model in LCC implemented. In the process an inaccuracy in the transmission line buffer handling was fixed and this improved the ULM implementation as well.
    • Internal Solver has synchronous machine T59/58 according to Karaagac (PS-dq0) implemented. No saturation or output of MFORCE/MANGLE at this point. Very similar results as native ATP versions, but less oscillations. Initialization according to Theory Book.
  • Patch 4 fixes
    • LIB-files were not written to disk for User Specified components (Exa_6 and Exa_11 examples)
    • Internal solver
      • ULM & Sections not properly handled if equal sections
      • RL couples lines had incorrect steady-state representation
      • Synchronous machine model fixes. MFORCE/MANGLE output. No saturation.
  • Patch 5 fixes
    • LCC Matrix Import with frequency dependent shunt admittance Y=G+jwC
    • Help files for machines updated
    • Internal solver SM-model optimized (still no saturation). No crash for unsupported components.
  • Patch 6 fixes
    • Accidentally misalignment of record structures. Reported showing up as problem loading projects with BCTRAN.

ATPDraw previous version (7.3), May 8, 2021

  • General update of sample frequency in Power System Toolbox. Sample frequency not restricted by simulation time step anymore.
  • Original COMTRADE object updated with the same sampling (up and down) approach as COMTRADE1 and COMTRADE2
  • Updates in multiple runs for LCC containing constant parameters. Avoids punch file creation and maintains multi-core operation. Speeds up this type of simulation significantly.
  • Plots. Improved appearance with right handle. GDI+ drawing. No Zoom rectangle after double-clicking. Copy bitmap. Vertical cursor included. Choose other series for x-axis (instead of time).
  • Sidebar. Extended width. Changes on simulation page. Different selection of time-domain vs. frequency scan with extended parameters in both. Removed some options to provide more room for Variables.
  • Variables. Extended in sidebar with optional column for parsed values for user selectable simulation number KNT. Better control and debug possibilities for Variable Values.
  • Variables. New selector @FILEA connects to an attached file in the project instead as on disc used by @FILE. @FILE selector extended to allow full path and not only ResultDir folder.
  • Variables. Maintained when pasting or importing (sub-)circuit.
  • EMTP_OUT. Selected UM machine number stored properly. UM TO TACS machine number left adjusted in ATP file.
  • Read old v3 projects (adp-file) with LCC/XFMR/BCTRAN data.

ATPDraw previous version (7.2), Sept. 12, 2020

  • New LCC approach without DataBaseModule (DBM) $INCLUDE. Node names inserted directly into the punch files. This allows a much larger number of phases (DBM approach restricted to 999 cards). New choice of Embed or $INSERT available, Embed recommended for small cases. Choice to cloned objects removed (same Name, copy content?). For $INSERT, all LCC components will get unique punch files written to disk with identified ‘1’..’n’ added to the component’s name. For old circuits, re-run of ATP is enforced to create new punch files.
  • Bug fix related to sectionalized PI-equivalents in LCC.CableConstants. Improvements in Verify.
  • Input dialog of TATPDrawPlot object updated with easier access to plot color, legend name and right axis and easier setting of axes and background. The advanced ChartSettings option moved in the back.
  • Open/Save dialogs not drawn in themed style (better user control, in file dialogs).
  • FluxN probe properly referenced in Selection menu.
  • UMSYN object showed wrong time constant Tq0’ instead of Td0’’ for Salient DQ-damper rotor.
  • In the optimization module, the Simplex Annealing setup is corrected and the error about the GA.txt file does not appear.
  • For multi-run cases, ATPDraw writes LIS-file error messages to the log-file and allows the user to abort the LIS-file scanning or skip sub-sequent LIS-file error boxes.
  • Main form of ATPDraw shown in the middle of the screen (not desktop) at startup.
  • MODELS input pl4 added.
  • Patch 1:
    • Fixes the hanging background process when using the native 'Windows' skin.
    • Support copy graphics (Ctrl+W) for Plots.
  • Patch 2:
    • Upgrade to newer compiler 10.4.1
    • Update in Plot, better handling of time axis with ms etc.
    • Critical fix when using Plot in combination with simulation error and non-existing PL4-files. Caused program crash with runtime 217 error.
    • Improved performance when reading PL4 file, and skipping those not subscribed to.
  • Patch 3:
    • Improvements in COMTRADE part for multiple runs. Previous versions stored all data for all runs in the COMTRADE object and this could result in some unexpected crash for large cases. Now, only the last run is stored inside (used in View/Copy) unless 'Merge results in multiple runs' is checked.
    • The COMTRADE object has the possibility to save the result as MatLab .mat v4 files. This supports multiple runs and allows a flexible way (user defined names and sampling frequency) to transfer results to MatLab.
    • The problem with invisible Additional objects when opening old project files from ATPDraw v4 is corrected.
  • Patch 4/5:
    • Proper handling of advanced Plot settings (problem with axis limits in patch 3-4). Direct call of advanced settings from context menu.
  • Patch 6:
    • Selection|'Read PCH file..' works also RL-coupled lines.
    • Lines PI and RL with 4 and 5 phases added to Standard component library.
  • Patch 7:
    • Significant change in the component UMIND. A change in v6 has been reverted back to the original topology with rotor reactance concentrated at the stator. This is how the fitting, torque plotting, and help file assumes it. It seems to be a mistake to locate the reactance at the rotor winding 1, at least without changing the fitting as well.
    • Single-phase Bergeron cable models do not get a correct punch file by ATP (missing transformation matrix or transposition flag problem). 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.
  • Patch 8:
    • Correction of variable handling in LCC and LCC_ objects. Previous versions did not recognize the variable unless the page containing the variable was active when OK was clicked.
  • Patch 9:
    • Correction of multi-circuit LCC PI-model individual circuit transposition. Previous versions gave a factor 1/3 wrong mutual zero-sequence impedances.
    • Correction of LINEPI6S help file in description of parameters. Minor update of other LINEPI help files for capacitance.
    • Bug fix in HFS_SOUR model supporting copy/paste of data.
  • Patch 10:
    • Correction of serious mistake in transposition of PI overhead line models in LCC. Accidentally a reactance value was mixed into the capacitance calculations.
    • Updates of the variable handling in LCC/LCC_ related to patch 8, ref Forum 5996. This speeds up the calculation process for multi-run cases without variables in the LENGTH, FREQ and GRNDRES data, for example Exa_21.acp. The speed-up in cases with LCC variables, requires a larger fix that comes in v7.3

ATPDraw previous version (7.1), July 18, 2020:

  • Upgraded to latest compiler version Delphi 10.4 Sidney. This supposedly solves high DPI screen problems, right-click context menu and current projects under Windows menu.
  • Significantly updated COMTRADE support with arbitrary sampling. Three different versions with various 3-phase and/or analog-digital inputs. COMTRADE moved to Selection menu|Probes&3-phase.
  • Flux-linkage probes for both 3-phase and single-phase, with initialization at t<0.
  • Plot object for direct, embedded plotting. Multiple-run support. NEWPL4=0/2 only.
  • Patch 2:
    • Fixes the exception error when start-up without network connection.
    • Fixes the scaling problems of toolbar and main menu after restore.
  • Patch 1:
    • Fixes error related to open certain projects containing LCC-objects (related to icon update). Strange bug related to new compiler issue.
    • Reverts the attempt of high DPI awarness and self-scaling. ATPDraw is now scaled by system on high DPI-screens as in older versions. Really no point to go self-scaling anyway without updating all icons.
    • Update the COMTRADE 3-phase component with the Peñaloza sampling algorithm. Exa_26.acp is not updated, however.

    • COMTRADE file generator added (found under Power System Toolbox). Downsampling and up to 18 analog and 9 digital channels supported in ascii or binary IEEE 1999 format. Tested with SIGRA software.
    • Additional new components; ABC2DQ0D, ABC2DQ0I, ABC2XYZ, CAR2POL
  • Patch 6 (does NOT include help- and project file fixes from patch 1-4) corrects the following
    • Serious double transposition error for PI-type cables with Snaking checked.
    • Connections between different phases, when Cancel was pressed in the Connection dialog got white color and thus appeared invisible.
    • W!RELAT87T when plotting the trip zone (View) asociated Istep2 with the differential current instead of the restraint. It only involved the plotting not the trip logic.
    • TRAPCHRG source got incorrect icon when Amplitude was set to -1
    • Statitical tabulation On checkboxes didn't repond correctly.
    • When loading old circuit, ATPDraw incorrected checked the Variables with the Internal Parser which fails for RAN and GAUSS function (maybe more).
  • Patch 5 (does NOT include help- and project file fixes from patch 1-4) corrects the following
    • SPLITTER having user specified node names on the single-phase side is managed.
    • LCC (template) objects with the same name get equal LENGTH, FREQ and GRNDRES data enforced.
    • Line&Cable/'Read PCH file' identifies line length for Clarke and KCLee lines.
  • Patch 4 (includes patch 1-3) fixes the incorrect storage of BCTRAN nonlinear core characteristics.

    • Several component dialogs (nonlinear, USP, Additional) could not show the built in text editor when it was already open via ATP|Edit ATP File or ATP|Show LIS-file ('Cannot make a visible winow modal' error message). This applies also to Preview option in the Output manager.
    • The same fundamental error shown up even more seriously after simulations in the case of showing simulation errors and when the 'capture screen output' option in the ATP Connection setup was used. It could lead to the mysterious runtime error 217 crash.
    • The TRAFO_S component keeps the RMS setting from the input dialog.
  • Patch 2 fixed the following issues:
    • Extended help file ATPDraw.chm with better access from ATPDraw. The help file system is also available online.

    • XFMR bug-fix:
      • Typical Core with inner winding of different rating than primary gave matrix calculation error.
    • Transposition of PI-equivalents in LCC. This is not natively supported by ATP, but ATPDraw now does this manually. Supports individually transposed circuits also for more than two circuits.
    • 6-phase RL and RLC lines with individually transposed circuits.

  • ATPDraw.scl (definition of standard components)
  • ATPDraw.chm (help file)
  • ATPDraw.ini (ini-file) (delete to use standard set-up)
  • Example files 1-28 in /Projects. Zipped binary files with extension acp.
  • A few example library files in the /USP, /MOD, and /BCT directories
  • ATPDraw stores its settings in ATPDraw.ini preferably located in %APPDATA%/atpdraw (documents and settings/user/application data/atpdraw)

ATPDraw is only a pre-processor to the ATP package which requires a licence. A separate post-processing tool is also required. ATPDraw can be set up to execute ATP and a plotting program directly via ATP|ATP Connection (F10). A licence for ATP can be obtained free of charge from the EEUG organization.
