The paper describes the development of substation Emulator for Electric Power Distribution System (EPDS) in Nigeria using Akure as the case study. The line diagrams of Akure EPDS were transformed into a PC-based Distribution Network with each node representing the various substations. The geo-information attributes of these substations were captured and integrated with the digitized map of the network. To facilitate real-time data gathering, Remote terminal units were connected to the substations to monitor the status of the substations using threshold passing algorithm and communicate the distribution control centre whenever changes are observed. The information is used by the developed engineering software to update the digitised network. The system provides the opportunity to study the dynamic behavior of Akure EPDS
