A. Control Authority Transfer Scheme for NTAMC/RTAMC/Backup NTAMC

Both the SAS Gateways shall be configured to report independently to three control centers of NTAMC system (Main NTAMC, Backup NTAMC & RTAMC) simultaneously. There shall be a Control Center Authority Transfer scheme implemented such that at a time, only one Control Center shall be able to Control the Substation. Any Control center shall be able to takeover supervisory control authority from the substation gateway for either / both main system / auxiliary system after substation is manually put in remote mode from local station. The information regarding which control center is having the control authority shall be known to all the other control centers. The total points in the substation will be categorised in two Groups either as "POWER" or "AUXILLIARY". The Control Authority transfer to a Control Center shall be possible for any of the groups i.e. POWER or AUXILIARY or both. This takeover control logic shall be implemented in the SAS Gateway.

B. Substation Level Local/Remote Switch

A Substation Level Local/Remote switch shall be provided prefarably in SUX BCU Panel in control room. The function is to transfer the supervisory control from SUBSTATION level to the CONTROL CENTER level. The controls shall be from SUBSTATION if the switch is in LOCAL position. It will be from the CONTROL CENTERs (Main NTAMC /Backup NTAMC / RTAMC) if the switch is in REMOTE MODE. The Control Authority Transfer shall be applicable when in REMOTE MODE.

C. Station ID shall be a unique number for each substation to be provided by NTAMC Control Center

D. A Dummy Circuit Breaker to be provided in the Aux BCU Panel in Substation Control Room to test healthiness of the communication link including Substation Gateway / RTU from NTAMC control center. The associated control & monitoring indication to be hard wired to Aux BCU for the same.
