Design of Main Step-Down Distribution Sub-Station(MSDSS)[33/6.6 kV in relation to the projected load & voltageregulation]

Design & Lay-out of above switch yard and inter linkingsystem networking. Design of Sub-Transmission Lines (33 kV), HT Lines (6.6 kV)and LT (0.415kV) lines including conductor/cable/ supportingstructures. Design of protection & control for 33 kV, 6.6 kV & 415 Voltsystems.

System connectivity should be sustainable, reliable and

affordable.

Development of Sub Transmission-system (33 kV) is toensure quality of supply, along with bringing down thetechnical losses to an optimal minimum value .

By quality power supply mean voltage regulation with in alimit laid by Grid code.

Optimal use of existing network infrastructures ofTransmission Utility (OPTCL) and/ or concerned Distributionlicensee.

Direct connectivity from Grid S/S interface for Concentratedload (Cluster points) & minimum linkage with DISCOMsnetwork except for those isolated schemes.


5/26

Create common asset with reduced financialliability and would take care technical needs ofcluster points.

Network development should be in integrated

manner, so as to, conserve ROW & would meet thefuture loads of the MLIP- Concept of IntegratedOptimal Strategy & Optimal location of MSDSS/DSS.

Phasing of works can be done depending upon the

materialization of Projects.

Compliances with OGC (Odisha Grid Code) &Distribution (Supply) Code & other relevantregulations in force.

High sub-transmission losses.

Redundancy (N-0)

EHT Back-upAll three Grid S/S need system augmentation including capacity addition.

Compliance with

OERC (Condition

of Supply)

Code,2004

Cluster being considered an Unit, Power supply shall be at 3 , EHT (System Load exceeds 15 MVA)

New Grid

Facilitate to comply with the Planning criteria ( Voltage regulation & system loss)Facilitate Reduction in System Loss & thereby reduce anticipated Energy charges payable by the Beneficiaries.

Benefit of additional power availability in the command area & enhance power reliability , quality of power

supply.


22/26

Following phasing proposed: Phase-I ( schemes with out system constraints)

Group-I (11 schemes), that shall initially fed from nearbySaintala Grid. [ ID (15,260,13), 11, (12,262), (261,10),(33,263,34)].

Subsequently these schemes shall be pooled into new dedicatedGrid to form a single source of supply for entire Cluster, for bothoperation & billing.

Phase II ( schemes that attribute to poor VR)

Group-II (4 schemes), that shall be developed in tandem withdevelopment of new 132/33 KV, (2x12.5) MVA Grid S/S in theproject area. [ ID31,264, (32,265)] or linked to local DISCOMnetwork.

Note: All schemes are under the jurisdiction of WESCO

except (ID 31 & 32) that fall under SOUTHCO
