Our client, an energy provider in the Southeast, sought assistance from Patrick's geospatial services team for their Interactive Volt Var Control (IVVC) project. This project involves integrating load tap changers, voltage regulators, and capacitor banks using controls, telecommunications, and IT systems. Performing these integrations conserves energy by flatting demand and reducing system losses while ultimately reducing costs. A careful analysis is required to integrate a circuit and locate where it should be placed. The analysis is run utilizing our client’s GIS. Critical data elements that must be checked to ensure compliance are the phase and size of a transformer, as well as the phase and wire size of tap lines. To verify that the data was useful for GIS analysis, our client utilized drone technology to conduct inspections. The drones were used to fly the primary backbone conductors of the project circuits and collect high resolution imagery of the equipment along the circuit. The client then had linemen inspectors review the aerial photography and compare it with location data in the GIS.

To complete the inspections, Patrick's geospatial services team created an ArcGIS Web Application (WebApp) within their ArcGIS Portal environment. The WebApp allows inspectors to review the drone imagery and mark locations of discrepancies between information in the photos and their GIS. “Comment” points are then used by a GIS technician to update their GIS. The inspectors have a tool that improves identification and reporting of asset maintenance needs and concerns. The inspector can locate and denote maintenance needs as they inspect. ArcGIS Desktop is then used to create a maintenance report that includes the photo, an overhead aerial of the site, and a street map that can be used to generate a work order.
