Understanding kml and pwt file formats
KML (Keyhole Markup Language) is an XML-based file format used to display geographic data in mapping applications such as Google Earth and Google Maps. It stores geographic features like points, lines, polygons, and images with their coordinates and attributes.
PWT (PowerWorld Transmission Line Data) is a proprietary file format used by PowerWorld Simulator, a software tool for power system simulation and analysis. PWT files typically contain data about transmission lines, including their electrical properties and geographic layout, for use in power grid modeling.
How to convert kml to pwt
Direct conversion from KML to PWT is not natively supported by most GIS or power system software, as these formats serve different purposes. However, you can follow a multi-step process to achieve the conversion:
- Extract transmission line data from KML: Use GIS software like QGIS to open your KML file and export the relevant line features (representing transmission lines) to a CSV or shapefile format.
- Format data for PowerWorld: Open the exported data in a spreadsheet editor (e.g., Microsoft Excel) and arrange the columns to match the PWT format requirements (typically including fields like line name, endpoints, resistance, reactance, etc.).
- Save as PWT: PowerWorld Simulator allows importing line data from CSV or Excel files. Use File → Import → Transmission Line Data in PowerWorld Simulator to import your formatted data and then save the project as a PWT file.
Best software for kml to pwt conversion
- QGIS: Free and open-source GIS software for extracting and exporting KML data.
- Microsoft Excel: For editing and formatting data to match PWT requirements.
- PowerWorld Simulator: The only software that can create and save PWT files. Use its import features to bring in your formatted data.
There are no direct online converters for KML to PWT, so using the above workflow is the most reliable method.
Summary
While there is no one-click solution for converting KML to PWT, using GIS and spreadsheet tools in combination with PowerWorld Simulator allows you to transfer geographic transmission line data into the PWT format for power system analysis.
