(b) Energy data disPlaY:

Energy parameters are displayed in workstation and r iewer PCs for rncters in various

f-eeders in the form of single line diagram'

(c) Data Logging and RePorts

linergy data wil l be logged in the server and Linergy consulnptiorl t 'epofts wil l be

generated for analysis. Reports wil l be geueratcd on daily, rnonthly or periodically

basis. Facil i ty to print rcports on laser printer wil l also be providcd. Thc tbllowing

repofts shall be Provided:

l) power generation / consurnption report - Shift wise, Daily, Weekly, Monthly and

yearly basis: For cach switchgear board, powcr consumption paratleters of

incoming / outgoing t-eeders shall be displayed. For all generators, power

generation parameters shall be displayed'

Z) Sipgle Line Diagranr: For each switch board, prcsence of energy meter / numerical

relay is indicated as brtnrap. Instantaneous values l ike V, A, PF, KWII, KVAR, F

shall be displayed below each feeder.

3) Load flow: Direction of load (active & reactivc power) flow alongwith the present

value of load (active & reactive power) shall be indicated for each switch board.

4) pLF- report - plant Loaci F-actor Report, Shifi wise, Daily, Weekly, Monthly and

yearly^basis: Plapt Loacl Factor reports are gcltcrated based on actual ge rlcration Vs

I{ated CapacitY.5) Breaker ON/OFF sratus: Breaker ON/OFF status shall be indicated on the

respective SLDs, whcrever such infonration is available throtrgh data

concentrators / package PLCs to EMS'

6) ILcal time wavefomr display (Online trends) firr select parameters shall be made

avarlable. The real t ipre wavefbrm display wil l clepcnd on the response time of data

.cquisit ion as the analog parameters are being acquired through data concentrators

/ package PLCs.
