SCADA means supervisory control and data acquisition.
It is a type of software application program for process control.
SCADA is a central control system which consists of controller's network interfaces, input
or output, communication equipments and software.
SCADA systems are used to monitor and control the equipments in the industrial process which
include manufacturing, production, development and fabrication.
In this video we will show you what is scada and Working Procedure of SCADA.
Normally Scada system could be a centralized system that monitors and controls entire area.
it's purely software package that's positioned on top of hardware.
A supervisory system gathers data on the method and sends the commands control to the method.
The Scada could be a remote terminal unit that is additionally referred to as RTU.
Most control actions are automatically performed by RTUs or PLCs.
The RTUs include programmable logic device which may be set to specific demand.
as an example, within the thermal powerhouse the water flow is set to specific value or
it is modified according to the need.
Now will we show Working Procedure of SCADA system?
The SCADA system performs the following functions.
Data Acquisitions.
Real time system consists of thousand of components and sensors.
It is very important to know the status of particular components and sensors.
For example, some sensors measure the water flow from the reservoir to water tank and
some sensors measure the value pressure as the water is release from the reservoir.
Data Communication.
The SCADA system uses wired network to communicate between user and devices.
the real time applications use lotof sensors and elements that ought to be control remotely.
The SCADA system uses internet communications.
Alldata is transmitted through internet using specific protocols.
sensing element and relays don't seem to be able tocommunicate with the network protocols
thus RTUs wont to communicate sensors and network interface.
Information Or Data presentation.
The normal circuit networks have some indicators which can be visible to control but in the
real time SCADA system, there are thousand of sensors and alarm which are impossible
to be handled simultaneously.
The SCADA system uses human machine interface (HMI) to provide all of the information gathered
from the various sensors.
Monitoring or Control.
The SCADA system uses completely different switches to operate} every device and displays
the status at the control area.
Any a part of the method will be turned ON or off from the control station using these
switches.
SCADA system is implemented to work automatically while not human intervention however at essential
thingsit's handled by man power.
Applications of SCADA system.
Power generation, transmission and distribution Water distribution and reservoir system
Public buildings like electrical heating and cooling system.
Generators and turbines Traffic light control system
