The streamlining of processes from a fully automated, self-healing network is obvious. Outage times can be reduced dramatically, and the numbers of customers impacted can also be cut down.
But the vast majority of FLISR's in use today are field-distributed, hardware-centric versions. These cost much more per end point customer being served, and the expense is linear. In other words, both the initial purchase and operation & maintenance costs do not decrease as the system grows.
ADMS provides a dynamic, model-based system, so the operations technology (OT) cost drops off dramatically once you have the ADMS model built from GIS and operating. Adding more schemes in your system is automatic from the OT perspective as you purchase and install additional (lower cost) switch gear in the field.
With this model, GE is powering our customers’ industry-leading use of ADMS-based FLISR, and we have the best overall success rate of getting full systemwide ADMS deployed -- the essential underpinning of self-healing FLISR.
For one North American GE IOU customer running FLISR in production with closed loop operation, FLISR was able to restore 9,488 customers in less than 2 minutes during a thunderstorm. The following week it restored 5,308 customers in less than 1.5 minutes.
In a single year this customer had 32 successful FLISR events with a 3-minute average restoration time, with approximately 20,000 customers restored automatically.
At the same time, FLISR’s data insights help better target the efforts of crews reconstructing switches or addressing faults in the field. Further, when FLISR is running on the network and providing intelligence to the switches (directly to automated switches or smart sensors) or funneling the relevant information to the crews handling manual switches, the computational and engineering power needed to determine the best plan of action in an outage is minimized.
FLISR is quick and efficient at figuring out what is happening and what should happen and adapting as the environment and inputs change. With FLISR isolating faults, making decisions, and doing it that much faster, utilities are finally getting the tools they need to get back up and running fast in the face of unprecedented weather wackiness.
