Scada systems automating electrical distribution

  1. 1. SCADA Systems Automating Electrical Distribution Presented by: SHUBHAM SAINI
  2. 2. INTRODUCTION WHAT IS SCADA?? SCADA (supervisory control and data acquisition system) refers to the combination of telemetry and data acquisition. SCADA encompasses the collecting of the information via a RTU (remote terminal unit), transferring it back to the central site, carrying out any necessary analysis and control and then displaying that information on a number of operator screens or displays. SCADA system consists of one or more field data interface devices ( RTUs or PLCs).A communication system such as radio, telephone, cable, satellite,etc. A central host computer sever or severs (also called a SCADA center, or Master Terminal Unit (MTU)).
  3. 3. COMPONENTS OF SCADA The SCADA system usually consists of the following subsystems: • A Human–Machine Interface(HMI) is the apparatus or device which presents process data to a human operator, and through this, the human operator monitors and controls the process.
  4. 4. • A supervisory (computer) system, gathering (acquiring) data on the process and sending commands (control) to the process. • A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects. THERE ARE BASICALLY TWO TYPES OF RTU:  Single Board RTU.  Modular RTU.
  5. 5. • A programmable logic controller, PLC or programmable controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. • Communication infrastructure connecting the supervisory system to the remote terminal units. Various process and analytical instrumentation
  6. 6. WORKING OF SCADA A SCADA system for a power distribution application is a typically a PC- based software package. Data is collected from the electrical distribution system, with most of the data originating at substations. Depending on its size and complexity, a substation will have a varying number of controllers and operator interface points. Data from the PLC and the devices is then transmitted to a PC-based SCADA node located at the substation. Ethernet-based and are implemented via the Internet, an intranet and/or some version of cloud computing.
  7. 7. Main Functions of SCADA
  11. 11. CONCLUSION SCADA provides management with real-time data on production operations, implements more efficient control, improves plant and personnel safety, and reduces costs of operation. 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.
