Tripping logic SMPPTRC

Identification

Function description
Tripping logic

Application

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
