Supervisory Control & Data Acquisition (SCADA)
Central Tech now offers classes in SCADA systems, advanced courses in Pipeline Electrical and Instrumentation, and a new class in Cyber-Security, which was developed through Central Tech to aid in preventing terrorist attacks on the nation’s pipelines. There will also be specialized long-term classes for those who want to work in the Control Room of an Oil and Gas company.
SCADA systems are used for monitoring and controlling gas and oil pipelines, power plants, water supply facilities, heat supply grids, and combined control centers for municipal suppliers. SCADA systems help achieve the flow of oil or gas along the pipelines, while monitoring pressure and flow, detecting leakage and fraud, and reducing operating costs.
SCADA system usually consists of the following subsystems:
- A human–machine interface or HMI is the apparatus which presents process data to a human operator, and through this, the human operator monitors and controls the process.
- A supervisory (computer) system, gathering (acquiring) data on the process and sending commands (control) to the process.
- Remote terminal units (RTUs) connecting to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.
- Programmable logic controller (PLCs) used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs.
- Communication infrastructure connecting the supervisory system to the remote terminal units.
