SCADA Communication System of Dhaka Power Distribution Company (DPDC)

Abstract

Supervisory Control and Data Acquisition (SCADA) is an acronym that stands for Supervisory Control and Data Acquisition. It is a centralized control system that is widely used in the power industry to monitor and regulate plant equipment, processes, and resources such as energy, water/wastewater, petrochemical, and manufacturing. SCADA was created and implemented to aid in the management and control of the country's essential infrastructure, complete with remote communications. SCADA communication is critical to the operation of this supervisory control system. The reliability of the SCADA system is thus heavily reliant on the SCADA communication sector. As a result, communication technology should be employed so that the reliability of the SCADA system is not jeopardized. Since 1998. ABB went on to develop it. Since its inception, the DPDC's communication sector has seen little progress. At the moment, the SCADA Communication sector is plagued by numerous issues that are rendering the entire structure obsolete. The communication structure is based on microwave links, and the purpose of this work is to propose a new communication technology known as Free Space optical Communication to improve system reliability. The transmission of modulated visible or infrared (IR) beams via the air to achieve optical communications is referred to as free space optics (FSO) or optical wireless. Free Space Optics (FSO) employs lasers to transfer data in the same way that fiber does, except instead of containing the data stream in a glass fiber, it is transmitted over the air. It provides a safe and cost-effective alternative to conventional wireless technologies.
