FirstEnergy Distribution Automation


Collectively each of these DA implementations

add up to greater than 25% improvement in

overall circuit CMI

■ FISR

– Fault Isolation Service Restoration

1. Electronic Recloser isolates fault to

fewer number of customer

2. Automatic Restoration completes partial

restoration

3. Control Center puts the crew on the

repair quicker

FE Integrated Volt/Var Control

Reliability focused

• Maximize Power Quality - Optimize voltage

levels, flatten voltage, prevent voltage sags

• Reactive Support - Provide reactive support to

the transmission system

• Respect Voltage Limits - 106% to 98% of

nominal, minimizes device operation

Energy efficiency / cost savings focused

• Loss Minimization - Flatten voltage, reduce

losses - both kW & kVAR

• Minimize Demand - Reduce kW while still

providing acceptable voltage


Integrated Volt/VAR Control


Reduced customer energy usage and improved power quality through

automated voltage management

Benefits of an Integrated Smart Grid Solution

CIGRE / FirstEnergy DOE Experience, Grid of the Future 23

■ Provides line of sight for grid operators all the way down to

the consumer endpoint

– DA & IVVC devices can be coordinated to optimize results

– AMI meters provide service level voltage

– IVVC can help synchronize voltages

■ Adds flexibility to accommodate distributed generation,

storage potential and other advanced distribution

technologies

Questions


Appendix


27

■ Traditional circuit design brought power from a generating source

to the substation and then to end use customers

Reclosers R1, R3, R6, R7

Breakers A1, A2, B1, B2

Circuit Ties for DA


Circuit Ties (continued)

■ Customer Benefits: allow customers to be served from multiple

sources; facilitates modern grid architecture

28

Example: Fault

occurs between A2

and R3; Customers on

remainder of circuit

can be restored by a

manually closing a

normally open switch

shortening the duration

of their outage


Circuit Ties w/

Manual Switches

Still Requires a

Truck Roll

Reconductoring for DA

■ When creating new circuit ties, wire size needs to be increased

to accommodate new power flows on the lines

■ Customer Benefits: facilitates power flows from multiple sources;

improves the resiliency of the line making it better able to

withstand adverse weather conditions

29

Line workers reconductoring a circuit


Reclosers

■ Reclosers divide up the distribution circuit into small sections

■ Customer Benefits: improved restoration times and fewer

outages by isolating faults to smaller groups of customers

30

Example: Fault

occurs between

A2 and R3; R3

automatically

opens; R9 or R4

automatically

closes and
