INTRODUCTION

MATTRANS is a package of MATLAB(R)/Simulink (M-files and .mdl files) for solving transient stability. It is intended as a simulation tool for researchers and educators that is easy to use and modify. MATTRANS is designed to give the best performance possible while keeping the code simple to understand and modify. It was initially developed in 2008 and the files can be found at: https://www.ee.iitb.ac.in/~anil/download/Transient_Stability_Programs/. The MATTRANS has been developed on the basis of these files and tried to follow the DRY (Dont Repeat Yourself) coding principle as much as possible. The MATTRANS project has been initiated for the research project of "A comparative assessment of PMU Data based Catastrophic Indicators for Power System Stability Assessment". Currently, the paper is under the review process. The MATPOWER (http://www.pserc.cornell.edu/matpower/) coding design principles has been inspired to develop the MATTRANS, which inherently uses MATPOWER package to execute the steady-state power flow. MATTRANS can be downloaded from the https://github.com/gelliravi/MatTrans/archive/master.zip

TERMS OF USE

Please see the LICENSE file for the details. But here is the summary:

  • MATTRANS is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY.

  • While not required by the terms of the license, we do request that publications derived from the use of MATTRANS explicitly acknowledge that fact by citing as:

      ------- cite.bib file ------

  title = "{MATTRANS: A MATLAB Power System Transient stability Simulation Package}",

  month = {Jan},

  }
  ------- EOL: cite.bib file ------

GETTING STARTED

System Requirements

  • MATLAB(R) version 15 or later (available from The MathWorks, Inc. (http://www.mathworks.com/). The MATTRANS is tested on MATLAB R2015b (Simulink 8.6). However, various compatible formats of the Simulink models for the main transientStability.mdl have been exported. The codes automatically detect your Matlab(R)/Simulink version and automatically uses the concerned Simulink model file. Hope this resolves the crucial hectic of version compatibility problems. For any concerns, please contact: [email protected].

  • MATPOWER (http://www.pserc.cornell.edu/matpower/), which is needed to execute the steady-state power flow.

Installation

  1. Download the MATTRANS from: https://github.com/gelliravi/MatTrans/archive/master.zip

  2. Unzip the downloaded file. Move the resulting MATTRANS directory to the location of your choice. These files should not need to be modified, so it is recommended that they be kept separate from your own code. Let $MATTRANS denote the path to this directory.

  3. Add the following directories to your MATLAB path:

    • $MATTRANS - all MATTRANS functions
    • $MATTRANS/src - core MATTRANS files

Running MATTRANS

To run a simple transient stability on the 4 machine 10-bus system specified in the file case10.m (steady-state data) and case10dd.m (dynamic data), with the default algorithm options, at the MATLAB prompt, type:

Example 1:
runts(data.case10, data.case10dd)
% all case files are placed in the data folder. Hence, it is needed to use data prefix to find the folder.
% data.case10 - It is a .m file, which has steady-state network data and the format is same as MATPOWER 
case format.
% data.case10dd - It is a .m file, which has dynamic-data of the above network and the format is defined 
as MATTRANS casedd format.
% While execution it prompts the user to enter some inputs, which are:
    If NO action to be taken, PRESS ENTER for every prompt. Or else the following values can be tried.
    Fault initiation time (s), Tfault= 0.5
    Fault Duration,(s) Tclear= 0.1
    Faulted Bus: 9
    Line(s) to be tripped, [ , ]= 9

Example 2:
runts(data.case145, data.case145dd)
% While execution it prompts the user to enter some inputs, which are:
    If NO action to be taken, PRESS ENTER for every prompt. Or else the following values can be tried.
    Fault initiation time (s), Tfault= 0.5
    Fault Duration,(s) Tclear= 0.1
    Faulted Bus: 7
    Line(s) to be tripped, [ , ]= 16

For additional info:

  • help runts
  • Proper documentation of the MATTRANS will be provided as early as possible. Meanwhile, if any assisstance needed please don't hesitate to contact: [email protected]

WHAT'S IN VERSION 1.0

Below is a summary of the 1.0 of MATTRANS. See the CHANGES file in the docs directory for all the gory details.

  • New features:
    • Execution of Transient stability program, which uses both coding and simulation environment of MATLAB.

DOCUMENTATION

The detailed documentation of the MATTRANS will be added as early as possible. However, MATLAB's 'help' command can be used for the functionality of MATTRANS codes.

ACKNOWLEDGEMENT
