Critical review Of SCADA And PLC in smart buildings and energy sector

Abstract

SCADA systems proves to be a promising technology to automate dynamical systems. Many automated systems around the world are built using the principle of SCADA. The Open-SCADA gathers, archives, visualizes, and transmits data among other functions. With SCADA-packages, you can save time developing large distributed systems by using pre-built components. It is also possible to modify your local operating system by using built-in tools and configuration. The Programmable Logic Controller (PLC) on the other hand has the benefits of simple function, fast speed, high dependability, high noise resistance and excellent stability, which serve to be highly advantageous for automated control applications. There is a wide range applicability of PLC in our present market. The studies examined the application of PLCs in engineering studies, energy production research, controlling and automating industry. PLCs certainly have limits, but data show that they have more pros than cons. Thus, PLC may be utilized for any application, whether the control system is basic or complex. This paper along with detailed review of SCADA and PLC discusses about power distribution & SCADA system architecture, the proposed control & monitoring scheme deployed in a real-time network which ensures that at any point of time, power supply is available through proper breaker interlocks at every level of switch boards in their respective substation. To ensure this, even at the SCADA communication network redundant OFC cable and ethernet switches are maintained at every level of RTU’s. A detailed case study of how PLC and SCADA are deployed in critical building application is further elaborated.
