5.3 LOAD SHEDDING PANEL

As described in clause 5.9.10 of the Functional specification no. FS 4019 (the functional
specification for control, relay, synchronizing and load shedding panel.)

NOTE

• All blank columns and Data marked with asterisk (*) shall be filled up by Vendor.
• The relays shall be of multi protection and multi metering electronic intelligent type (
microprocessor based numerical programmable logic relay ).
• This Data Sheet for TG incomer has not been provided and shall be developed by contractor
for purchase requisition based on requirement given in FS4040 and shall be submitted to
company for approval.
• At MNW, Alstom make load shedding panel is provided which is interfaced with HV drives
and generator cubicle of MNW but same is not working and needs to be disconnected.
After disconnection of interfacing of HV drives and generator cubicles of MNW, the same
shall be extended to MNP load shedding panel by providing and executing suitable
interface equipment and multi core cable.
• In addition to the generator annunciation points, contractor shall decide additional
annunciation points as per requirements mentioned elsewhere in bid package during
detailed engineering and provide the same in the generator control panel.
