3BTELECONTROL FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
M has an absolute value greater than 1. Here over reach has been achieved so
the offered results are not accurate since no actual impedance parameters have
been considered for the location of the fault.
2.3. TELECONTROL FUNCTIONS
2.3.1. SMART P2P PROTOCOL
smART P2P is a communications protocol for the smART P500 relay that allows for a
fast, optimized and reliable information exchange. This information exchange is used for
the remote control among relays in order to conform protection systems that take in to
account the status of another relay in the decision making process as for example in the
teleprotection systems (POTT, PUTT, etc). The states received from the other end can
be combined into local states in order to allow or block trips as well as any other
interesting application. The Figure 2-55 show this applications.
Now only allows the use of this protocol in RS-232 later port of protection, with the
configuration shown in Figure 2-54
