UDC assisted PG&E develop a schematic model and perform the subsequent conversion of the GIS data using an offshore team of 30. UDC performed DAT (data acceptance testing) of all 4,400, 500-scale schematic diagrams. Over one million primary features were edited and white spaced according to a set specification as developed by UDC and PG&E.
PG&E’s objective for this project was to develop and maintain a schematic model representation of its GIS to aid departments such as outage management and engineering. UDC provides the manpower and expertise to maintain this vital system ensuring that the schematic model is never more than one to two working days out of synchronization with the GIS. UDC performed the original model setup and subsequent schematic data conversion and continues to give ongoing program support.
UDC currently maintains the converted electric schematic dataset by completing any GIS edits that affect the primary network represented in the dataset. Six UDC technicians maintain the schematics changes made daily (SUPs) by editing the placement of affected schematic features and moving required annotation using Esri’s schematic editing tools. Edits are made according to a specification defining feature and annotation white spacing rules and guidelines. Annotation is checked to ensure it is associated with the correct feature.
- Over 33,000 schematic update polygons (SUPs) are processed annually.
UDC’s Wisconsin team provides production manpower, project management and system troubleshooting as well as works with PG&E IT to perform UAT (user acceptance testing) of periodic updates and enhancements to the model.
