Geographic data and drawings

Electrical case files describe equipment and operating values. Geographic and drawing files describe where to display that equipment. Tellegen uses PowerIO’s GeoLayer for both, keeping the coordinate system explicit.

GeoJSON, CSV, and AUX files can supply geographic bus positions and line routes. PowerWorld PWB files can also contain geographic bus locations. PowerWorld PWD files supply drawing positions and polylines. A drawing appears on a plain canvas; geographic coordinates appear on the map.

Drop companion files together, or select a case before attaching another file. The attachment report lists matched equipment and unmatched objects. A later attachment to a demo creates a local copy, preserving current demand changes, line capacities, and the current result. No unrelated recent case is selected.

When a case has both geographic data and a drawing, use Map or Diagram to choose the view. Save a Study to retain both layers, line paths, and the current camera position. Drawing coordinates stay in their source units.

Shared GeoJSON

A GeoLayer uses a FeatureCollection with Point and LineString features. The powerio_geo member records geographic, projected, drawing, or unknown coordinates. Equipment matches by stable identity, source ID, name, or branch endpoints. BMOPFTools bus_from and bus_to names are accepted.

PowerIO reads the proposed BMOPFTools embedded bus[id].geo and line[id].geo values. Explicit BMOPF output retains geometry under extras.geojson, which is permitted by the currently identified draft schema. This supports edited coordinates without claiming that the Task Force has approved new schema fields.

Download geography exports geographic positions and routes. Download drawing exports the selected drawing as a GeoLayer. Both can be reopened by other PowerIO consumers.
