How Small Utilities Are
Finding Success With Advanced
Distribution Management Systems
(SCADA) system; fault location, isolation, and service
restoration (FLISR); and other distribution management
systems applications for many years. This case study
discusses the following results achieved by the utility:
* a decrease in the System Average Interruption Frequency Index (SAIFI) of 32%
* a nearly 50% decrease in the System Average Interruption Duration Index (SAIDI)
* 20% less time spent by field crews on outage repairs.
The case study reviews how the utility was able
to increase employee confidence in ADMS applications and quickly train operators and other users. It
also shares lessons learned to help other small utilities
install an ADMS successfully.
✔ Case Study 2: This case study profiles a utility that is just
beginning its ADMS journey. It wants to use a SCADA
system to control DERs. To make the project affordable,

it has partnered with a government entity on a project to
evaluate models for integrating grid-friendly DERs. The
case study assesses the utility's motives for enacting an
ADMS, the required initial work, and its advice to utilities on funding and prioritizing ADMS projects.
✔ Case Study 3: This case study features a utility halfway
through its ADMS journey. Due to the terrain, 20% of
its distribution lines must be overhead with exposure
to vegetation, which causes outages that can trip both
overhead and underground portions of lines. The utility first upgraded its SCADA system to an integrated
ADMS platform and applied FLISR to gain reliability
improvements through automation. This case study discusses the infrastructure required to enable the ADMS,
the importance of interoperability and platform selection (see Figure 1), lessons learned, and the value the
utility has seen, to date, with its implementation.
