Application of INSILCOTE RTV silicon

rubber coating at 132kV Bay of 35 MVA

TR-1 & 2 (Transformer Bushings, CT, PT

And circuit breaker)

NA

Hydrophobicity of INSILCOTE

inhibits the formation of

continuous moist conductive

layers on insulator surfaces. This,

in turn, limits the flow of leakage

currents, thus preventing the

creation of dry bands and partial

discharges – critical steps in the

flashover process.

S.No. Action Plan

1

APC Scheme of RAS & BWR need to be reviewed & updated/modification according to

the connectivity with SMP

2 Tie feeder -2,3,& 4 loading need to be maintained near to Zero MW

3 Close monitoring of cement plant start & stop

4 Auto/ frequency based laod shedding to be reviewed

5

Possibility of Load management for BWR & RAS generation and also daily priority of

cement plant loading

6 Power flow at tie feeders is dependent on the running availability of SMP unit-1&2

7 Relay co-ordination settings of all the tie feeders

8

Segregation of power flow in all the tie feeders in case of any outage of cement plant

load or any shorfall in generation

9 Bus voltage to be monitored and controlled at SMP, SP & RAS end individually

10

Preparation of separate SLD & APC schemes with Iso/ Droop mode for better learning &

understanding while running the whole system with SMP

11 Review of Iso/ droop logics of 2x50MW & GPP-2,3&4 when running in parallel mode

12 Possibility of running any one 50MW TG at iso mode and the other at droop mode

13 Cement Plant U-X & RNCU start & stop staus to be reviewed

14 Load flow analysis & study with different scenarios at E-tap

15

In case of any 132kV Tie feeder tripping , check the feasibility of 10/12.5 MVA

transformer charging for 2x50MW auxiliary

16 Cement Plant under frequency shedding to be reviewed

17

Switching ON/OFF the capacitor banks at cement plant as per requirement of MVAR

demand

18 Changeover of modes of running Generators AVR & governer mode in case of contigency

19

Rate of change of frequency (df/dt) settings at respective buses to be reviewed for all

cement plants (U-03 to 10)

20 Checking of the control wiring of the tripping of cement plant drives

21 Tap changer operation need to be reviewed at all points

22 MW set point to be disabled in case of any islanding condition

23

Allocation of man power in cases of C-shift at RAS PP CCR for better control &

monitoring purpose.
