SUBSTATION ALARAM MONITORING SYSTEM
[attachment=25542]
SCADA
It supervises, acquires and control data received from various sensors and the sends that data to central computer.
Supervisory control:
Control of many individual controllers by automatic or human control systems.
Data acquisition:
It is the gathering of source data for data entry into the computer.
APPLICATIONS OF SCADA
POWER PLANTS
RAILWAYS
INDUSTRIES
ADVANTAGES OF SCADA
FLEXIBILITY
PORTABILITY
SECURITY
EFFICIENCY
DESIGN GOALS AND STRATEGIES
To disseminate tripped and non-tripped alarm accurately to reflect changing system conditions.
To disseminate alarm data in timely manner when needed.
To streamline and consolidate the process of telemetry data acquisition.
To promote SCADA data sharing.
To increase work effectiveness in regional offices and NLDC.
CONCLUSION
SAMS can be utilized to disseminate substation information quickly and accurately.
As a result power system break down would be alerted promptly and restoration time could be reduced.
SAMs also allows operational information to be shared among TNBT personnel.
With reasonable investment on development and maintenance, SAMs has proven to be a cost-effective and flexible system that can be incorporated into any future SCADA system.
