SCADA for Thermal power plant.
ABSTRACT :
Thermal power plant is one of the essential part of the power system. In the Thermal power plant the power is generated when water is boiled in the boiler as coal is ignited in the ignition chamber due to which the steam is produced which is given to the turbine which converts physical energy into mechanical energy then this mechanical energy so produced is given as input to the generator where the mechanical energy is converted into the electrical energy. This process is easy to explain but this process has to run continuously and consistently so that output from the generator is maintained constant. As generator output has to be maintained constant there is requirement of monitoring and controlling of this process.
In early days of mid 1930’s distributed control systems (DCS) where in use which had the ability to just control the system and did not contribute a lot in analysis of the system either in normal operation or in the fault condition.
In 1960 Allen Bradley introduced a concept called “SCADA”. SCADA is an acronym for Supervisory control and data acquisition. SCADA is not just a software nor a hardware it is the combination of the special hardware, software and protocols.
The SCADA for thermal power plant allows the owner of the plant not only to control and supervise the plant which is its features but also allows to operate the plant in the economical way. SCADA for thermal power plant overrides all the drawbacks of the conventional DCS based thermal power plant. It does not entertain more manual operations instead operates automatically hence overriding the human errors and minimizing the errors in the power plant operation.
