General Description of Project
Project:
Stacker Reclaimer to CCR IO Communication using Wireless
Customer Information:
NTPC Korba, Dist. Bilaspur.
Solution for Wireless Communication by:
Sheetal Wireless Technologies Pvt. Ltd., Pune.
PO No:
4000043908-M55-1017 dated: 21/05/2010
Objective:

• KSTPS, NTPC Korba, : In Coal handling plant Stacker Reclaimer were using
control Reeling Drum (Flexible control Cable ), CRD motor, slip rings for
carrying field IO signals to CHP control room for monitoring and controlling of
the machines .
• To avoid frequent breakdown of machines due to break in control cables , to
increase the system reliability and to avoid routine maintenance cost , NTPC
has opted the wireless solution for establishing the communication link
between Stacker Reclaimer and Control centre .

WHY WIRELESS:
• To reduce the Installation time
• To make use of the flexibility which only wireless can offer
• Ease & Speed of deployment
• Easy for expansion
• Cost reduction, compare to cabled solutions
• Negligible maintenance cost
• Ease of implementation and installation
• Real-time Alarm Annunciation

System Selection Criteria & Consideration
For the above communication system, license free band is considered due to following reasons
• IEEE 802.11g is Open Standard: So License is not required .
• 54Mbps Signaling rate over 20MHz channel.
• AES Encryption technique is used for data security.
• 12 digital signals are transmitted from each stacker for status Indication & 4 Digital signals are transmitted from CHP CCR to each stacker to control multiple processes.
• The device provides flexibility to user to go online to access remote PLC, Edit Upload & download the PLC programs remotely.
• This system provides full duplex Voice communication between stacker PLC cabin & CHP CCR for communication between Operation team & machine operator, which was not provided by the previous system.
• This system can be terminated in Plant EAPBX as well.
• Huge bandwidth can be used for video surveillance of stacker machines as future expansion.
