x Control and power cable lists for AC/DC power distribution ,earthing andgrounding requirements.

Layout Engineeringx Control Rooms layouts, Control equipment rooms, Battery Rooms, UPS

rooms, SWAS rooms etc


8/20

Projects Being Engineered Concurrently( In-House)

x New -14

x R&M -3

x Diverse DCS Systems -6

x Functional testing in a year-10-12

x These figures will increase substantially for projects

to be engineered in future.

C&I EnggEngg. Activities a snapshot


9/20

Stringent targetsx C&I Specification preparation time w.r.t zero date has

come down from 6 months tonow -4 in bulk tendering projects)

x Documents review & approval time reduced

x Cost reduction in all packages including C&I

x

Minimization of Project to Project Variants ( Eg,C&I Layout)

x FAT time reduction though scope of testing

increased

C&I Engg. ActivitiesC&I Engg. Activities a snapshoa snapshot


10/20

` Tender Phase Two Stage Bidding ( Specification better tuned to

contemporary systems)

Standard Specification Module ( Streamlining the Specs.Preparation process)

` Engineering Phase

Specialization based Dept. Structure ( Detailed focus onspecific area; continuity & consistency in Engg.; single ptinterface to sites)

Standardization in Engg. Process.


11/20

Pre-engineering of systems UPS, 24V DC charger.

All logics/ loops tested in laptops with the vendor before

Integrated test.

Major Design Features test for DCS before FAT.

Standardization of Documents (Interconnection Drawing

etc).

Standardization of Control Room/ Control Equipment

rooms layout. Automation in Engg. Process (ICS generation for main

plant & offsite).


12/20

` In On-going Projects

x

Practice/ Concept

Uniform Control System for main plant as well as offsite ( DCS Platform)

for ease of maintenance, uniform HMI, optimized operation.

Uniform Logics Philosophy/ Tagging for Offsites in line with main plant.

Facility of remote operation of hydro plant from Corporate Centre.

Multiplexing of Programmer room hardware for space saving and

optimized usage.


13/20


Practice/ Concept

Reduction in Control Hardware

Testing and Commissioning Tool of DDCMIS for site activities

PADO Results dissemination back to DDCMIS & to any PC on Plant

Intranet

Online Control loop tuning software in Station C&I package.

Contd..
