Intelligent distribution automation system

Abstract

Supply disruption such as overloading will cause interruptions of electricity power supply to customers. This research presents the development of a customer side distribution automation system (DAS) for operating and controlling low voltage down stream of 415/240V by using the Tenaga Nasional Berhad (TNB) distribution system. An embedded Ethernet controller is used as Remote Terminal Unit (RTU) to act as converter for HMI to interact with digital input and output modules. The Supervisory Control and Data Acquisition (SCADA) system software includes software modules such as graphic editor, database setup, alarm configuration, trending tools and communication setup. HMI monitoring system is correctly showing the fault point and generates the correct alarm messages for the operators to be acknowledged. The SCADA system developed provides automatic fault isolation, monitoring and controlling functions for the operators and data collection for future analysis.
