132/33 KV Main Step-Down Sub-Station-5 inaugurated at RSP

Rourkela: As a part of the power augmentation package of the ongoing modernization and expansion programme of Rourkela Steel Plant (RSP), the newly constructed 132/33 KV Main Step-Down Sub-Station-5 (MSDS-V) was inaugurated by S N Roy, ED (Works) on Tuesday here.

MSDS-V comprises a 132 KV Gas Insulated Sub-station (GIS), four 63 MVA 132/33 KV Transformer, two 33 KV Indoor Switchboard and several other state-of-the-art facilities. The 132 KV GIS is not only the first of its kind in RSP but also in the State of Odisha. Set up by M/s Siemens Limited this sub-station is fed from CPP-II as well as from MSDS-II (Grid Power) through new 132 KV double circuit transmission lines.

With MSDS-V coming to stream an alternative path for evacuation of power from CPP-II is now available at 132 KV level. The 132 KV GIS is a trouble free system requiring very little maintenance as compared to the conventional 132 KV Air Insulated Sub-station. Also, there is no safety hazard involved in GIS as all the live parts are encapsulated.

MSDS-V shall serve as the power centre for all Rolling Mill loads ensuring uninterrupted power supply to three major units namely Cold Rolling Mill, Hot Strip Mill and Plate Mill. Besides, power for the entire Steel Township shall be fed from this sub-station. Now that existing Rolling Mill loads have been taken off from MSDS-III after commissioning of MSDS-V, the existing MSDS-III with its expansions is ready to feed power to the Expansion Units like Coke ovens Battery-6, Blast Furnace-V, Sinter Plant-III, Caster, Ore Bedding and Blending Plant etc.

Among others, Dipankar Basu, ED (P&A), R K Nehru, ED (MM), M K Das, ED (Projects), S K Acharya, ED (Projects), S K Jain, ED (Projects) from SAIL Corporate office and other senior officers from RSP, MECON & Siemens were present on the occasion. A K Bihari, DGM (Projects) leader of the Projects (Electrical & Civil) of this project coordinated the programme.
