Self Healing Grid

Yukon Feeder Automation is an advanced Self Healing software system that can be deployed across the distribution network that integrates real-time data from the distribution system to detect disturbances, automatically reconfigure the system to isolate the disturbance and minimize the total number of customers impacted.

The Self Healing Grid is a system comprised of sensors, automated controls, and advanced software that utilizes real-time distribution data to detect and isolate faults and to reconfigure the distribution network to minimize the customers impacted.

One of the main goals of a Self Healing Grid is to improve system reliability. This can be accomplished by reconfiguring the switches and reclosers installed on the distribution feeder to quickly isolate the faulted section of the feeder and re-establish service to as many customers as possible from alternate sources/feeders.

Self Healing solutions typically need to reconfigure the system within one to five minutes. To accomplish this it may require communications bandwidth in excess of what is typically provided by AMI systems (5-8 kbps). A utility can enable feeder automation solutions using a mix of higher bandwidth radios, cellular, fiber optic and WiMAX or BPL. Cooper Power Systems offers flexible communications options allowing the utilities to leverage existing communication infrastructures and upgrade to newer communication infrastructures in the future.

Many utilities also want to leverage the use of existing switches/reclosers and associated controls as far as possible. Therefore, vendors must be capable of reviewing existing equipment, recommending upgrades and performing the upgrade work if required and integrating to as much legacy equipment as is reasonable.

Enterprise applications such as SCADA/DMS must be able to access status of feeder devices, the state of the feeder as well as disable/enable automation functionality. The automation solution that is implemented for enabling automation can also be used to manage the connectivity of the feeder IEDs to the enterprise.

Utilities often require that operational and non-operational data from the feeder IEDs is made available to Engineering, System Planning and other defined groups within the utility, without traveling to the IED. Self Healing Grid solutions such as Yukon Feeder Automation should have provisions for the required integration of data and tools that can be used to analyze the data.

Cooper Power Systems Self Healing solutions improve feeder reliability by re-configuring switches or reclosers to isolate the faulted portions of the system and restores the healthy feeders to improve reliability performance (SAIDI, SAIFI).

Cooper Power Systems also offers the following types of Self Healing solutions, click on the link below to learn more:

Loop Scheme Reclosers (LS)
Using loop scheme reclosers provides automatic feeder isolation and loop sectionalizing without the need to utilize communications.

Automatic Source Transfer (AST)
Automatic Source Transfer quickly transfers load from one source to an alternate source for critical loads such as hospitals and process industrials. This utilizes logic shared between two controls to increase the response times and can transfer in 8-10 cycles.

Premium Power Quality Services
These services allow critical customer centers such as commercial and industrial parks to be served from multiple sources. High speed operation isolates the fault with minimal or no impact on customers.
