Using Edge computing to reduce costs
GE Gas Power Controls uses GE Digital’s Edge technologies in its HRSG (Heat Recovery Steam Generator) Life Monitoring application (version V3), which performs key life expectancy calculations to estimate life consumption of HRSG components that are often subjected to significant operating cycles, thermal transients, long-term high temperature operation and condensate build up, and more, resulting in fatigue and creep of critical components. The application runs on top of GE Digital’s Predix Edge platform and uses GE Digital’s Proficy Historian Edge for time-series data storage at the edge. It is deployed globally in conjunction with both GE and non-GE HRSGs, improving performance and reducing costs.
Edge computing to assist a remote workforce
Predix Edge eliminated a huge data ingestion barrier and allowed a North American energy company to more than double the collected tag volume per monitored site. GE Digital’s Power Generation and Oil & Gas Services team is doing an in-place upgrade of the fleet, minimizing downtime, enabling data collection growth, and removing migration barriers. The greater data collection rates will enhance outage optimization planning and reduce downtime.
Each site takes just 15 minutes on average to migrate from the legacy technology to Predix Edge, and GE Digital plans to deploy Predix Edge across all 28 power generation systems as the project extends to wind assets. The cloud administration capabilities of the Predix Edge collection system also help offset the strain of a remote workforce during the COVID-19 pandemic.
In the two examples above, both companies were able to achieve a higher ROI, leverage the security features architected into Predix Edge and Proficy Historian Edge, manage devices at scale, flexibly apply their edge solutions and leverage turnkey and offline capabilities by consuming Predix Edge as a baseline for edge computing and data ingestion scenarios respectively.
