A new automated compact substation for distribution system in Malaysia

This project has developed a new distribution automation system and remote metering system. It is a customized distribution automation system (DAS) for secure fault isolation at the low voltage (LV) downstream, 415/240V by using the Tenaga Nasional Berhad (TNB) distribution system. It is the first DAS research work done on customer side substation for operating and controlling between the consumer side system and the substation in an automated manner. Most of the work is focused on developing very secure fault isolation whereby the fault is detected, identified, isolated and cleared in few seconds. Supervisory Control and Data Acquisition (SCADA) techniques has been utilized to build Human Machine Interface (HMI) that provides a graphical operator interface functions to monitor and control the system. Microprocessor based Remote Monitoring Devices have been used for customized software to be downloaded to the hardware. Power Line Carrier (PLC) has been used as communication media between the consumer and the substation. As result, complete DAS fault isolation system has been developed for cost reduction, maintenance time saving and less human intervention during faults. This research has developed Automated Meter Reading (AMR) system in addition to DAS

Novel Automated Fault Isolation System on Low Voltage Distribution Automation System

This novel automated fault isolation system has been developed and integrated into a new customer side distribution system of 415/240V. The distribution system is based on the Tenaga Nasional Berhad (TNB), the Malaysia's power utility company especially the distribution system. Supervisory Control and Data Acquisition (SCADA), Remote Terminal Unit (RTUs) and power line communication (PLC) system have been used and developed for detecting, fault locating, fault isolating, fault segregating and power restoration in terms of hardware and software. Open loop distribution system is the distribution configuration system used as TNB distribution system. It is the first distribution automation system (DAS) based on fault management research work on customer side substation for operating and controlling betweenthe consumer side system and the substation
