Supervisory control and data acquisition (SCADA) is an industrial control system which is used in many modern industries like energy, manufacturing, power, water transportation, etc. SCADA systems organize multiple technologies that allows to process, gather and monitor data at the same time to send instructions to those points that transmit data. In today’s world, almost anywhere you can observe SCADA systems, whether it’s a waste water treatment plant, supermarkets, industries or even in your home.

SCADA systems range from simple to large configurations. Most of the SCADA applications use human machine interface (HMI) software that permits users to interact with machines to control the devices. HMI is connected to the motors, valves and many more devices.

SCADA software receives the information from programmable logic controllers (PLCs) or remote terminal units (RTUs), which in turn receive their information from the sensors or inputted values which we have given manually. SCADA in a power system is used to collect, analyze and monitor the data effectively, which will reduce the waste potentially and improve the efficiency of the entire system by saving money and time.

As the power system deals with power generation, transmission and distribution sectors, monitoring is the main aspect in all these areas. Thus the SCADA implementation of power system improves the overall efficiency of the system for optimizing, supervising and controlling the generation and transmission systems. SCADA function in the power system network provides greater system reliability and stability for integrated grid operation.
