- Slide 3
- Simulate two line terminal substation in lab For testing,
training, and demonstration purposes Use SEL (Schweitzer
Engineering Labs) line relays Simulate Breaker in Hardware HMI
(Human Machine Interface) Control, status, and alarms of breakers
Learn about: DNP (Distributed Network Protocol), SEL RTAC
(Real-Time Automation Controller ) HMI interfaces
- Slide 4
- One rack was built as complete line terminal DNP functionality
needed to be added Second rack needing to be rebuilt from
scratch

- One line diagram Breaker Status and Control Individual Breaker
Pages Breaker Status and Control System Voltage Reclose Enable
Carrier Cutoff
- Slide 8
- Breaker status Color indicates open or closed Breaker control
Double click breaker to bring up open or close commands
- Slide 9
- Separate Page for each Breaker Breaker Status and Control Other
commands that are used at substations
- Slide 10
- SEL-3530 RTAC Connects to PC via USB or Ethernet Used DNP over
Ethernet to communicate with SEL-421 and SEL-411L relays Used DNP
over RS232 to communicate to SEL-321 relay
- Slide 11
- SEL-421, 411L, 321 System is setup with one line-relay per
breaker Communicates with RTAC via DNP Trips, closes and receives
breaker status via 125 Volt DC discrete circuitry Used our company
standard relay inputs and outputs
- Slide 12
- Existing Rack Represents Single Line Terminal SEL-421 and 311C
redundant line terminal relays SEL-351S breaker relay Reclosing,
Breaker Failure, etc. Only SEL-421 Communicates to RTAC DNP Over
Ethernet Trips, closes and receives breaker status via 125 Volt DC
discrete circuitry
- Slide 13
- Used custom logic SEL-421 to simulate four breakers Reasons for
421 Availability Buttons, lights, timers are contained in one unit
Easier wiring than original plan Programming could be expanded to
allow for different failures Breaker failure, Slow trip, fast
reclose, etc.

Status (52A) OUT205:Opposite state of Out201 IN205: Closes Out201
IN101 or IN201:Opens Out201

- Choosing hardware and laying out wiring Obtaining hardware and
software Learning to use the SEL graphical logic to get breaker
simulator working Getting logged in and communicating to all
devices Passwords, baud rates, and IP addresses werent always easy
to find Learning to use DNP map in relays
- Slide 20
- Learning about RTAC as absolute beginner SEL has a helpful
video series on YouTube that starts at more basic level than the
manual Getting first status point working from relays Getting first
control point working from relays Learning to use Diagram Builder
Getting diagram to display
- Slide 21
- Get DNP to SEL-321 working Bring back more alarms and statuses
to HMI Add different types of failures to breaker simulator
