4. Quickstart Guide Plotter
The MTB Plotter is a tool that allows plotting of the generated RMS and EMT results.
The tool is located in the folder "plotter" which includes the main script "plotter.py", subscripts, a figure setup file and a configuration file.
Before running the main script, you should configure both the figure setup file and the configuration file itself.
4.2 Configuration of config.ini [MTB > v2.0]
The plotter configuration file, config.ini,
contains the following modifiable parameters:
| Parameter | Type | Default | Description |
|---|---|---|---|
| [config] | |||
| resultsDir | string | results | The relative path for plotter results folder |
| genHTML | boolean | True | Whether or not to generate HTML plot result files |
| genlmage | boolean | True | Whether or not to generate image plot result files |
| genCursorPDF | boolean | True | Whether or not to generated PDF cursor output files |
| imageFormat | string | png | Plot image format, either png or jpeg |
| htmlColumns | integer | 2 | Number of HTML columns produced |
| imageColumns | integer | 3 | Number of image columns produced |
| htmlCursorColumns | integer | 2 | Number of HTML columns produced |
| threads | integer | 10 | Number of Python threads for producing result files |
| testcaseSheet | string | -- | Path to testcases.xlsx (mandatory) |
| [Simulation data paths] | |||
| PathlLegendName | string | ..\export\MTB_XXX | Path1 for RMS or EMT data directory, e.g. RMS |
| Path2LegendName | string | ..\export\MTB_YYY | Path2 for RMS or EMT data directory, e.g. EMT |
| Path3LegendName | string | -- | Path3 for RMS or EMT data directory |
| etc. |
Note
If htmlColumns > 3, the HTML output will be a "subplot" with a common legend on the righthand side instead of each plot figure having its own legend.
Tip
The paths under the section header [Simulation data paths] can be appended to compare additional results from multiple models. Simply add a new line matching the folder containing the data one wants to plot.
The strings Path1LegendName, Path2LegendName, etc. used for each data path will be appended in front of all the signals names from that specified data path. It could be as simple as e.g.
- EMT
- RMS
or more elaborate if different versions of RMS and EMT results are being plotted to compare results from different versions, e.g.
- RMS_V04,
- RMS_V05,
- EMT_V04,
- EMT_V05,
- etc.
The plotter tool automatically categorizes results found in the paths of the [Simulation data paths] section header. An RMS result file is defined as a .csv file with the leftmost column named b:tnow in s and an EMT_INF result file (metafile) is defined as an .inf file with the first line starting with PGB(1). _EMT_INF_datafiles (*.csv) are assumed to be in the same folder as the .inf metafile. All files with extension .psout are assumed to be of type EMT_PSOUT, the new binary-based PSCAD output.
Note
The plotter tool also supports .csv and compressed .csv output generated by the psout_to_csv.py script
| Type | Enum | Description |
|---|---|---|
| RMS | 0 | PowerFactory standard .csv output |
| EMT_INF | 1 | PSCAD legacy .inf/.csv output |
| EMT_PSOUT | 2 | PSCAD new style .psout output |
| EMT_CSV | 3 | PSCAD .psout -> .csv support |
| EMT_ZIP | 4 | PSCAD .psout -> .zip, .gz, .bz2 and .xz support |
4.3 Configuration of figureSetup.csv
The figure setup file, figureSetup.csv, is used to configure individual plot figures. A maximum of three EMT signals per EMT result file, and three RMS signals per result file can be specified for each plot figure.
| Column | Description |
|---|---|
| figure | Figure number (currently not used) |
| title | Figure title to be used for each plot figure |
| units | Units to be displayed on the y-axis for each plot figure |
| emt_signal_1 | Name of first EMT signal to be plotted for each figure |
| emt_signal_2 | Name of second EMT signal to be plotted for each figure |
| emt_signal_3 | Name of third EMT signal to be plotted for each figure |
| rms_signal_1 | Name of first RMS signal to be plotted for each figure |
| rms_signal_2 | Name of second RMS signal to be plotted for each figure |
| rms_signal_3 | Name of third RMS signal to be plotted for each figure |
| down_sampling_method | Down sampling method to use [gradient (default) | amount | no_down_sampling ] |
| gradient_threshold | Only valid if down_sampling_method = gradient was selected (default = 0.5) |
| include_in_case | Comma separated list of values of all the cases the specific plot figure should be included in |
| exclude_in_case | Comma separated list of values of all the cases the specific plot figure should be excluded from |
Tip
If more than two result files are specified in the config.ini file, e.g. (say) two EMT result files and (say) two RMS result files, the plot figure legend could have up to twelve signals in the plot figure legend, and the plot itself could have up to six EMT signals and six RMS signals.
In such cases it would be better to maybe specify only one EMT and oneRSM signal per plot figure. For the above example, this will lead to only four signals in the plot figure legend, and only two EMT and two RMS signals per plot figure
Warning
If down_sampling_method = no_down_sampling is selected, the HTML files can become quite large and might take quite a long time to load.
Note
If include_in_case is left blank, the figure plot will be included in all cases/ranks And similar, if exclude_in_case is left blank, the figure plot will not be excluded from all cases/ranks
The default figureSetup.csv can be easier edited using Microsoft Excel,
Caution
The CSV file used Danish regional settings which implies ';' should be used as field separator
The default signal selection in figureSetup.csv are:
- Phase-phase voltages at POC
- Phase-ground voltages at POC
- Positive- and Negative-sequence voltages at POC
- Total currents at POC
- Id current at POC
- Iq current at POC
- Active power at POC
- Reactive power at POC
- Frequency at POC
- Id current at POC measured by pll
- Iq component current at POC measured by pll
- Id and Iq currents, and positive-sequence voltage at a terminal
- Direct measurement at the generating unit's terminals (delete if not used)
- Instantaneous Voltage from the EMT model
- Instantaneous Current from the EMT model
Execute the "plotter.py" script after config.ini, see section 4.2,
and figureSetup.csv, see section 4.3 have been configured. The plotter results will generated in the results folder as defined in the config.ini file.
For this example, Case Rank 38 is shown below.
For the HTML results, note that you are able to navigate between the hmtl results by utilizing the buttons at the top, either navigating to the previous or the next rank number in relation to the testcases.xlsx sheet. To enable quicker navigation between results further away from eachother in terms of rank number, make use of the "More Ranks" drop-down menu, this includes a list of every fifth plot that can be navigated to.
Additionally, shortcuts are added to navigate through HTML result ranks:
- Alt + Page Up = Navigates to previous rank.
- Alt + Page Down = Navigates to next rank.
- Alt + H = Displays help message.
