Jemena sets “self-healing” network technology live – Software

A multi-12 months plan to create a “self healing” electricity network grew to become reality this week for vitality corporation Jemena, as it switched on a fault area, isolation, and service restoration technique (FLISR).

Intelligent assets manager Perry Rogers instructed iTnews that Jemena determined in 2017 that the two its NSW gas network and its energy community in Melbourne needed control methods that have been additional aligned with the electronic environment.

The old regulate infrastructure, Rogers spelled out, utilized “a great deal of components components made by the seller at the time”, and it was time to “move to a lot more standardised IT componentry”.

Jemena made the decision in early 2018 to deploy an state-of-the-art distribution management program (ADMS) platform from OSI.

With that foundational technologies in area early past 12 months, Rogers claimed, progress of the FLISR application on prime began in earnest.

In which Jemena has the communications infrastructure and units that communicate with FLISR, the software package gets telemetry from the network which implies fault problems, these kinds of as a excursion on the community.

“A fault can be the trip of a device, FLISR will detect that, evaluate the disorders on the community, and make a selection regarding how most effective to restore provide to buyers, as immediately as doable, and isolate the fault to as little a portion of the community as possible”, Rogers stated.

As soon as a fault is isolated, FLISR analyses energy flows on the network to select a ideal route to restore power to as a great deal of the community as doable, applying remotely-managed field switches.

With faults isolated to smaller locations, the number of clients impacted is minimised.

Electrical energy network operations manager Tim Pullens claimed the FLISR process will “help us achieve our goal of improving upon offer trustworthiness by 30 % by 2023.”

For most faults, Rogers explained, outage times would be diminished to “momentaries”, rather than sustained outages.

The procedure depends on Jemena acquiring swap gear on the community that is “FLISR-friendly”, he mentioned. 

“We now go into an asset management program to deploy far more distant-managed switchgear, which will allow FLISR to be much more powerful about the network, in excess of time,” Rogers explained.

That rollout will be completed over the next two yrs.

It also implies that what customers working experience when there’s an outage will be additional consistent, across the community.

“FLISR automation is not a man or woman – it’s an automated method,” Rogers mentioned.

“Effectively it will do the similar factor any time of the day or evening, with the exact consistency”.
