AEP IEC-61850 History
• UCA/IEC-61850 since late 1990’s
• MMS since early 2001 for SDR’s
• 1st Process Bus pilot project in 2007
• 2nd Process Bus pilot project in 2012
(Roberts, Sys1 - GE)
• 1st all fiber protection and control system
at Flag City (2015-2016)

1st Process Bus Project – Corridor
• 2007 worked with GE to pilot the installation of
the GE Brick at Corridor 345kV substation
• Bricks and GE relays were installed
• Goal of the project was to build confidence in the analog
values and time stamping for protection
• Lessons Learned
• Few faults at 345kV for data gathering
• Did not wire in tripping outputs for trip time comparison
• Provided a comparison for cost savings associated with
eliminating control cable to substation equipment
• AEP Protection Engineers learned very little and
built ZERO confidence in the ability to use the
GOOSE portion of IEC-61850 for protection
tripping functions 3
2st Process Bus Project – Roberts
• 2012 worked with GE to pilot fully integrated
protection system
• 2 Transformer Zones
• 2 Bus Differential Zones
• 8 Distribution Feeders
• System was in parallel with AEP Standard
protection system
• Wired contacts at the breaker to confirm trip
times over fiber connection
• Reviewed many fault operations on distribution
lines and gained confidence in system

Roberts Continued
• AEP Protection Engineers were able to build confidence in
the digital signals supplied to the brick from the relays. All
oscillography data confirmed in service hard wired
protection system trips to be 1 – 2 ms faster
• AEP Protection Engineers were able develop a high level
confidence that an installation using this platform will
provide cost savings
• AEP Protection Engineers were able confirm test procedures
that would be necessary to successfully commission a fully
integrated protection system using this hybrid IEC-
61850/Process Bus solution WITHOUT using specialized test
equipment

1st All Fiber P&C Substation - Flag City
• Distribution substation protected and controlled
entirely by fiber-optic technology
• Applying IEC 61860 coupled with GE Hard Fiber
technology
• Fiber optic cables replace about 85% of copper wires
in the substation (9000’ vs. 58000’)
• GE Bricks / GE UR provide entire substation
protection with no backup copper system

Network
• LAN consist of two Ethernet switches for failover redundancy
• SCADA, Engineering Access, 61850 MMS, Switch Management,
GOOSE, PTP

Factory Testing
• Factory tested at MEPPI the GE Bricks in May
• Wiring check
• Verified all inputs operate as specified
• Factory tested the DICM at Systems Control in June
• Wiring check
• Verified protection, alarms, monitoring, network

Next Steps
• September – DICM and switchyard equipment will be
installed and powered up
• Plug and work – Install fiber patch cables between
switchyard and DICM Fiber Splice Cabinet
• Re-test relays – Similar to Systems Control visit, relays
will be tested with GE Bricks
• In-service 12/1/2016
• New project at Roberts station
• Install SEL TiDL to validate technology
• Consideration for second relay system for
Transmission applications (Redundancy)
21
Roberts Sys2 – SEL TiDL
• Like 2013 GE Hard Fiber project, AEP must
validate SEL TiDL by installing and
monitoring performance
• Installation shall be completed by end of 2016
• TiDL will provide AEP transmission a
redundant and independent point-to-point
system to replicate existing relay standards
