SCADA or Supervisory Control and Data Acquisition is a system for monitoring and controlling generation, transmission and distribution of electrical power and energy. SCADA is a centralized system comprising of the following components: (1) host computer and database servers often known SCADA Center or MAster Station that gather and process data from remote terminal units distributed over the system, (2) a number of interface devices known as remote terminal units (RTUs) connected to sensors, programmable logic controllers (PLCs), switches, relays, etc., (3) a two-way communication system using standard protocols for transferring data and control signals between master station and the field devices and (4) a host of software and hardware providing the human-machine interface (HMI) function to operators in the SCADA.


SCADA is used for real-time collecting data from monitoring devices and remotely controlling equipment.
