SCADA SYSTEM –BENEFITS DERIVED (Contd.)Accurate reports for future planning of State Transmission

System.Saving in running cost by optimizing operation &

maintenance cost & reducing risk of failure of sub-station equipments.

Identifying potential risks to take preventive action in advance.

Accurate centralized information help in quality monitoring of power supply. Improved services to customer.

Longevity of equipment’s life by real time monitoring.Overcoming shortage of man power by automatic data

logging and generation of all system reports.Preparation of precise MIS & Performance Standards of

Transmission System for State Regulatory Commission. 8

ACHEIVEMENTS OF SCADA PROJECT Establishment of SCADA Control Centers at

Jabalpur, Bhopal & Indore with integration of Remote Telemetry Units (RTUs) at 313 Nos. EHV Sub-stations

Successful testing of RTUs delivered under the project for simultaneous reporting to three Master Control Centers through combination of Wide-Band OPGW-PLCC Channels and GPRS link using separate logical data bases in addition to reporting to Local Data Monitoring System (LDMS).

Implementation of SMS information system for Tripping of EHV Lines and Transformers.
