Tripping logic

Application

In SAM600-IO the SMPPTRC function is used for combining the trip signals from different bay
level IEDs into one. The start and direction functionality should not be used.
All trip signals from the different protection functions shall be routed through the trip logic. All
start signals and directional information can be routed through the trip logic as well. In its
simplest form, the trip logic will only link the TRIP signal to a binary output and make sure that
the pulse time is long enough.
Tripping logic SMPPTRC offers three different operating modes:
• Three-phase tripping for all fault types (3ph operating mode)
• Single-phase tripping for single-phase faults and three-phase tripping for multi-phase and
evolving faults (1ph/3ph operating mode).
• Single-phase tripping for single-phase faults, two-phase tripping for two-phase faults and
three-phase tripping for three-phase faults (1ph/2ph/3ph operating mode).
The logic also issues a three-phase tripping command when phase selection within the
operating protection functions is not possible, or when external conditions request three-
phase tripping.To meet the different double, 1½ breaker and other multiple circuit breaker
arrangements, multiple identical SMPPTRC function blocks are provided within the IED. In such
installation, use one instance of SMPPTRC function per circuit breaker.
If the OHL is connected to the substation via more than one breaker, one SMPPTRC function
block should be used for each breaker. For example when single-phase tripping and
autoreclosing is used on the line, both breakers are normally set up for 1/3-phase tripping and
1/3-phase autoreclosing. Alternatively, the breaker chosen as master can have single-phase
tripping, while the slave breaker could have three-phase tripping and autoreclosing. In the case
of a permanent fault, only one of the breakers has to be operated when the fault is energized a
second time. In the event of a transient fault the slave breaker performs a three-phase
reclosing onto the non-faulted line.
The same philosophy can be used for two-phase tripping and autoreclosing.
To prevent closing of a circuit breaker after a trip, the function offers a lockout function.
