NEED FOR R&M

As regards 500MW simulator is concerned,the computer and hard panel with instructorstation were supplied by M/s Siemens AG .Theyare no more in the simulator business.I/O

interface system were supplied by M/s TataPower. They are not in a position to give timelysupply of I/O cards and reliability is notfoolproof. Procurement and proper functioningof these cards have been taking even 2 years.The

prices of I/O cards are very high, on the groundthat most of the components used are nowobsolete & have to be procured at a higher cost.

We are facing same problem in 200MW

simulator.

Views about R&M: Minutes on the discussion of technical team in NTPC

held on 06/08/04-R&M of the existing 200mw & 500MWsimulator are required as advised by D(Opn.) and ED(OS).

Letter ref 01/PMI/Sim.upg/2004-Minutes of meeting,where D(HR) was present-It was felt that simulator200MW & 500MW are panel based and new technology(CRT based) simulators have come up in the market,wewould immediately go to renovate both the simulator.

M/s RTEDELTEC Corp. ,supplier of UPS system onKorba visits-Your unit have been out of production over20 years and there are no spares/parts available for them.My suggestion for you to replace your unit with a current

model.

NEED FOR R&MNTPC

NEED FOR R&MNTPC

New NTPC projects & other power utilities areoperated from LVS/OWS system and olderstations either from a totally hardwired UCB or

a mix of both. Thus operators tuned with bothtypes of experience are required over at leastten years from now.Hence, R&M of thesimulator by porting of existing software intonew hardware platform and augmenting it by

adding LVS/OWS based platform is the mostfeasible solution to the problem.

In view of foregoing, it is suggested thatR&M both the simulator may please be taken up

at the earliest

R&MACTIVITIES

The proposed R&M activities includes :

Replacement of existing ENCORE/GOULDsimulation and DAS computers by latest

servers.Replacement of I/O interface system with

latest DCS/PLC based system.

Replacement of obsolete panel hardware as on

required basis. Incorporating the LVS/OWS based operator

HMI.

Establishing network connectivity to PMI, so

that training may be provided at PMI.

NTPC

R&M PROCEDURES

As has been done in our DAS R&M cases,thewhole R&M activity is proposed to be done inseveral phases/steps in order to minimize thedown time.

Most of the software work can be done onthe new hardware platform and connectivityto the panel can be done with minimum down

time of say 15 days or less.During that time training will be continued

with existing configuration.

NTPC


13/19

PHASE-Replacement of existing ENCORE/GOULD

DAS and simulation computers by latest

PCs,servers,LAN switches,laser printers etc.Porting of the existing software system on to

the new hardware platform.

Replacement of I/O interface with latest

DCS/PLC based system .Up-gradation of panel hardware like meter,

recorders,indicator etc. on as required basis.

Replacement of annunciation system with

LED based system.

NTPC

R&M PROCEDURE(contd.)


14/19

R&M PROCEDURE (contd.)

PHASE- Fine tuning of simulation models to the present

state of the plant incorporating all modification

and up-gradation of plant, that may have beenimplemented over the years.

Up-gradation of instructor station facility likeautomated trainee exercise,grading functions.

One set of LVS/OWS based system may beinstalled in the existing computer room.

Connection will have to be established betweenthe simulator & plant DAS for analyzing plant

data.


15/19

R&M PROCEDURE (contd.)

PHASE- After the completion of all the R&M

activities the network connectivity may beprovided to PMI, so that both the simulatoroperation may be demonstrated at PMI.

Connectivity of Sipat simulator with PMI is

already envisaged so it can be extended toKorba.

BENEFITS WITH R&M

TANGIBLE BENEFITSAfter R&M we will have 4 panel, that will

accommodate more no. of trainees.

Simulator training cost (for 2 weeks) withLVS/OWS system is Rs.50,000/- as comparedto Rs.30,000/- with conventional system.

As on previous available data no. of traineesfor 2 weeks program = 1100(aprox.).,assuming that half of these traineesare for LVS/OWS based system.

Approx. cost of simulator training

=Rs.4,40,00000/-

BENEFITS WITH R&M

INTENGIBLE BENEFITS :The simulator training gives a feeling of

operating a real power plant with no fuel cost,

no wastage of time,no losses and repairs. It rises the level of proficiency and

confidence.

Training in emergency handling helps in

saving down time of plant.Training in efficient operation helps the

operator in improvement of overall efficiencyand life expectancy of plant equipment.
