ATPDraw latest version (7.6) August 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.

 

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 Karaagc (PS-dq0) implemented. No saturation or output of MFORCE/MANGLE at this point. Very similar results at 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.

  • 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 license for ATP can be obtained free of charge by applying from this web-site.
