Figure 103: Aided Distance POR scheme
The POR scheme is enhanced by POR Trip Reinforcement, and POR Weak Infeed features.
4.2.1
PERMISSIVE OVERREACH TRIP REINFORCEMENT
The send logic in the POR scheme is arranged so that for any trip command at a local end, the local protection
sends a Channel Aided signal to the remote end(s). This facilitates fault isolation at each terminal as quickly as
possible. The send signal is generated by the Any Trip command, and it is sent on any channel that is being used.
