Industrial revolution worldwide. It has resulted in social changes too and raised the standard of living we examine a future distribution system capable of solving problems caused by the connection of numerous distributed generators. A supervisory-control-and-data-acquisition (SCADA) system for this distribution system should be economical, flexible, and reliable, and should execute a real-time process. In this seminar report, we propose a SCADA system using mobile agents for flexibility. In addition, we show two types of communication protocols that make agent migration more fault-tolerant, and perform experiments where the SCADA system executes earth fault protection within the required time. These results indicate that the SCADA system based on our proposed technologies should be capable of fulfilling the real-time processing requirement. While writing the report on my seminar, I was wondering that Science and technology are as ever expanding field and the engineers working hard day and night and make the life a gift for us
