FLISR from ACS achieves automated restoration at SVEC

Atlanta – May 2, 2018 – Suwannee Valley Electric Cooperative (SVEC), announced that they had their first successful automated restoration occur on March 23rd, following the installation and implementation of their ADMS system provided by Advanced Control Systems (ACS).

Automated restoration occurs when there is a permanent fault on the power lines that results in a power outage, followed by a system automatically detecting the location of the fault, automatically performing switching to isolate the fault, then automatically performing switching to re-route power in order to restore power to those customers who
are out, but are not in the section of lines where the fault exists. Automated restoration typically restores power in less than 1 minute to those customers who are out of power, but not in the section of lines where the fault exists,versus the traditional restoration times.

Suwannee Valley Electric Cooperative, in Live Oak Florida, is a not-for-profit cooperative that provides safe, affordable and reliable electric service to more than 18,500 member-owners in the Florida counties of Columbia, Hamilton, Lafayette, and Suwannee. The decision to implement an ADMS system was driven by the Cooperative’s commitment to continuous improvement of service reliability and outage restoration times for its members. “It is satisfying to witness the FDIR portion of SVEC’s reliability plan improve service to our member owners” says Kurt Miller, Director of Engineering for SVEC. “SVEC is looking forward to completing systemwide FDIR in 2019 with Volt/Var optimization and peak demand management to follow in 2020” says Kurt.

“The decision to move to an ADMS platform is a big decision for any utility” says Kevin Sullivan, CEO of ACS. “We’re honored that SVEC chose ACS as their partner in this eff ort, and it’s always exciting to see a utility reach the milestone of their first automated restoration. Now SVEC can look forward to vast improvements in their service reliability for years to come”.

Advanced Control System’s Centrix vs. Irma

Advanced Control System’s Centrix vs. Irma

Centrix fault detection, isolation and restoration saves 82 million customer minutes in a day.

Hurricane Irma challenged the operations of a regional utility with the widest spread storm ever to hit the state in one day. The utility operates an automated feeder restoration system from Advanced Control Systems which detects service faults caused by the storm, then isolates the faulted network segments and restores power through its self-healing technology, within seconds.

This technology saved – in one day – 82 million customer minutes that would have been interrupted by long term outages caused by Irma. The previous five-year total saved 67 million customer outage minutes using Centrix. ACS’ Centrix with Fault Detection Isolation and Restoration protected 763 feeders, serving 1.3 million customer meters. In total, 78,963 customers were restored through Centrix self-healing networks.

PRISM Outage Management System vs. Harvey

PRISM Outage Management System vs. Harvey

How ACS’s pioneering PRISM system handled hurricane force outages

In September 2017, Hurricane Harvey blew through Texas, causing damage and widespread power outages. An ACS customer in South Texas provides electrical generation to electric co-ops serving 241,000 members in forty-two South Texas counties, so when power is not available, those 42 counties are without electricity. The utility had an added challenge – their control center is located on the river, which flooded. Utility employees had to spend the night in the plant, since the roads were closed, but they still managed to restore most of the widespread outages within 3 days.

The ACS PRISMTM SCADA/OMS system operated perfectly. The newly-installed OMS system worked throughout the storm’s duration, automatically generating service tickets and managing crew assignments with mobile capability. The topology processor provided a dynamically colorized version of Google Map of the outage areas, using GridVuTM. An abnormal amount of event alarms and outages were time-tagged and processed in the PRISM SCADA system. The number of customers out of service was calculated and displayed, giving state agencies and officials a view of everything that was happening. ERCOT (Electric Reliability Council of Texas) was even able to access the web site and view the status of the outages for the entire service area – to the degree that ERCOT did not have to call the utility for updates, leaving all hands free to keep the lights on and restore power. The customer said the ACS PRISM system helped save the day from an operational viewpoint.

The PRISM OMS application with a geographic outage map, applied to a transmission system, is unique to electric transmission (EMS) networks. ACS pioneered Transmission OMS, pertinent to transmission operations with a multi-Voltage level model (built with DASmapTM), map graphics and the transmission specific logic of trouble call analysis.
