APS, Bridge Energy Group Create Geospatial Visualization System

BRIDGE worked with APS to correlate and process data from 900 substations, 1200 transmission lines and 75 generating units.

BRIDGE Energy Group's  new Geospatial Visualization System has been deployed by APS in its energy control center. To improve situational awareness and enhance operators’ ability to proactively respond to potential problems, BRIDGE transformed thousands of data elements previously available only in table format into a visual display of the Arizona transmission grid.

BRIDGE worked with APS to correlate and process data from 900 substations, 1200 transmission lines and 75 generating units, delivering it to the control center transmission and balancing authority operators in near-real-time. The data are then displayed geospatially in map layers and graphically via dynamic dashboards.

“GVS provides our operators with greater situational awareness by providing a geospatial view of our transmission system. This allows the operators to assess and respond to real-time conditions and real-time contingency results more rapidly, enhancing reliability for our customers,” said Sarah Kist, director of Transmission Operations & Maintenance at APS.

GVS was designed to augment existing control systems. It is based on a combination of available commercial solutions, system integration and transmission operations expertise. The new method of grid monitoring collects data from a variety of systems and sources -- enabling the operational health of 842 contingencies to be visualized -- in real-time -- on a geospatial map. Using the layered geo-surface map, APS quickly evaluates hundreds of assets at a glance, while receiving visual alerts or “blooms” for components that exceed normal operational thresholds.
