One of our power utility customers wanted to use
advanced Numerical Relays which can do protection, CB control as well as metering functions for a power distribution automation project.
As per the conventional scheme, these relays could be interfaced to the RTUs thru RS485 in the substation and linked to the control centre over a comm link.
Can this scheme of using RTUs be dispensed with and only keep Numerical Relays to behave as RTUs, as some of the relays offered by reputed mfrs claim that they are compliant to any protocol? Our
apprehension is that will there be anything that we miss if we "dont go" for the RTU in this scheme?
Thanks in advance for the response.
