an introduction to scada.

  1. 1. AN INTRODUCTION TO SUPERVISORY CONTROL AND DATA ACQUISITION Fundamentals and Implementation SUBMITTED BY: RISHABH SRIVASTAVA 100105027 ELECTRONICS AND INSTRUMENTATION.
  2. 2. DEFINITION OF SCADA “Supervisory control and data acquisition, or SCADA, is the control technology that enables the operator of a controlled industrial process or plant to obtain data from one or more of its distant facilities and send limited control instructions to those facilities”
  3. 3. BASIC COMPONENTS OF SCADA. Four basic components of SCADA: • Sensors • Remote telemetry units (RTUs). • SCADA master units. • The communications network
  4. 4. • BLOCK DIAGRAM FOR BASIC SCADA SYSTEM.
  5. 5. BASIC FUNCTIONS OF SCADA. A SCADA system performs four functions: • 1. Data acquisition • 2. Networked data communication • 3. Data presentation • 4. Control • 5. Human Machine Interface.(HMI)
  6. 6. HUMANMACHINE INTERFACE (HMI) • What is HMI? • Role of HMI. • What Does HMI Comprise?
  7. 7. COMPARISION BETWEEN DCS AND SCADA. FEATURES DCS SCADA DATA TRANSMISSON ONE WAY TRANSMISSON TWO WAY TRANSMISSON CONTROL FULL ELABOTAED, GENERALLY FULL CONTROL LIMITED OR SIMPLE CONTROL INTERVENTION LIMITED INTERVENTION FREQUENT AND IMMEDIATE INTERVENTIONS
  8. 8. DIFFERENT USES OF SCADA SYSTEMS: Mass transit: regulate electricity to subways, trams and trolley buses; to automate traffic signals for rail systems; to track and locate trains and buses; and to control railroad crossing gates. Manufacturing: manage parts inventories for just-in-time manufacturing, regulate industrial automation and robots, and monitor process and quality control.
  9. 9. DIFFERENT USES OF SCADA SYSTEMS(CONTD.): Electric power generation, transmission and distribution: Electric utilities detect current flow and line voltage, to monitor the operation of circuit breakers, and to take sections of the power grid online or offline. Buildings, facilities and environments: Facility managers use SCADA to control HVAC, refrigeration units, lighting and entry systems.
