Abstract:
In today’s world most of the systems are operate on automation. Because of that the
automotive systems are most efficient. Automation means use of Programmable Logic
Controller (PLC) & Supervisory Control And Data Acquisition (SCADA) instead of
electromechanical devices. PLC & SCADA based distribution monitoring & control means
use of automotive system in electrical distribution system for monitoring the electrical
parameters (like voltage, current, power factor, etc) & controlling if any fault occurs in
electrical system with the help of personal computer (PC).
Electric power distribution system is an important part of electrical power systems in
delivery of electricity to consumers. Automation in the distribution field allows utilities to
implement flexible control of distribution systems, which can be used to enhance efficiency,
reliability, and quality of electric service. Presently, worldwide research and development
efforts are focused in the areas of communication technologies revolution and application of
IEC 61850 protocol in the distribution automation to make distribution automation more
intelligent, efficient and cost effective.
This report has proposed a model that illuminates the categories of data, functionality,
and interdependencies present in a SCADA system. Main concept of the project is data
acquisition and controlling by using SCADA software PLC. Here PLC is a medium between
electrical system and Personal Computer for SCADA to take input and output bits.By using
the parameters, we can easily control any load in our system to improve system operation,
system reliability, etc. alternatively, SCADA and PLC communication system make it
possible to integrate protection control and monitoring electrical parameter together for
maximum benefit. It also discusses about the present implantation philosophies and current
challenges in the distribution system automation. Further, EPRI ‘IntelliGrid’ project is
discussed as an example of advance distribution system automation. Finally, communication
aided advanced distribution system automation and its advantages are explained in detail.
