Monitoring bunker Level in Thermal power plant which was around 25 years old,with replacing old ultrasonic transmitter by modern day RADAR transmitter and inetegration of I/Os into existing system architecture.

1. NLC /TPS-II/STAGE-2 /BUNKER AUTOMATION/
RADAR LT PROJECT
• REPLACING OF EXISTING ULTRASONIC TRANSMITTERS WITH PROPOSED
RADAR LEVEL TRANSMITTER OF TOTAL 48 NOS. FROM UNIT-4 BUNKER
TO UNIT-7 BUNKER.
• ALL 48 ANALOG INPUTS WILL BE CONFIGURED TO THE EXISTING GE
FANUC 90-30 PLC SYSTEM NETWORK THROUGH NEW ANALOG INPUT
MODULES

2. BUNKER AT EL. 32 MTR
• NLC TPS-II Phase-2 has 4 boilers Unit-4 to
Unit-7
Each boiler has 6 bunkers
• Each bunker has 2 Level transmitters for
continuous Level monitoring as shown in fig
• Total of 48 nos. of Level transmitters for Unit-
4 to Unit-7
(2 Level tx *6 Bunkers * 4 Boilers)

8. SYSTEM UPGRADATION, ENHANCEMENT & MAX. AVAILABILITY
As GE Fanuc 90-30 CPU was an older version, further upgradation enables as
• Making the outdated components to present day updated technology
• Max. Reliability & availability of the system.
• Enhancing the availability & productivity
Requirements:
Risk assessment / Downtime / Process availability
