WHAT IS SCADA??
Scada is ” SCADA is a system operating with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station).”
WHAT IS POWER SYSTEM AUTOMATION
Power-system automation is the act of automatically controlling the power system via instrumentation and control devices. Substation automation refers to using data from Intelligent electronic devices (IED), control and automation capabilities within the substation, and control commands from remote users to control power-system devices.
INTELLIGENT ELECTRONIC DEVICE
Any device incorporating one or more processors with the capability to receive or send data/control from or to an external source (e.g., electronic multifunction meters, digital relays, controllers)
INSTRUMENT TRANSFORMERS
Instrument transformers are used to sense power system current and voltage values. They are physically connected to power system apparatus and convert the actual power system signals, which include high voltage and current magnitudes, down to lower signal levels
TRANSDUCERTransducers convert the analog output of an instrument transformer from one magnitude to another or from one value type to another, such as from an ac current to dc voltage.
METERA meter is an IED that is used to create accurate measurements of power system current, voltage, and power values. Metering values such as demand and peak are saved within the meter to create historical information about the activity of the power system
DIGITAL FAULT RECORDERA digital fault recorder (DFR), is an IED that records information about power system disturbances.It is capable of storing data in a digital format when triggered by conditions detected on the power system. Harmonics, frequency, and voltage are examples of data captured by DFRs.
PROTECTIVE RELAY
A protective relay is an IED designed to sense power system disturbances and automatically perform control actions on the I&C system and the power system to protect personnel and equipment.
SMART METER
In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load.

CONCLUSION
The government of India has decided to integrate all the state power utilities. Unified load dispatch Centre has to be build. So automation has lot more advantages as it increases efficiency and increase standardization. India is moving ahead toward automation are you??
