GEOSPATIAL MODELING OF ELECTRICITY DISTRIBUTION NETWORK IN IFE CENTRAL LOCAL GOVERNMENT AREA, OSUN STATE, NIGERIA

Abstract

Electric utilities have a need to keep a comprehensive and accurate inventory of their physical assets, both as a part of normal service provision (extending the network, undertaking maintenance, etc.) and as a part of their obligation to inform third parties about their facilities. Complexity of electrical distribution power system is a good reason for introducing new information technology - GIS (Geographic Information System) that carries out complex power system analyses (e.g., fault analysis, optimization of networks, load forecasting) in acceptable amount of time. In pursuance of an understanding of the electricity distribution network, the Geographic Information Technology approach was adopted. GIS provides a better scenario in the management and monitoring of electricity distribution facilities so as to provide adequate power supply for the resident sector of the economy. The aim of the project is to generate a geospatial model for electricity consumers and facilities to provide a better understanding towards effective distribution and conservation of electricity. This involves locating and mapping all the facilities involved in distributing energy to the end-users. This modeling involves the collection of both the geometric and attributes data of all the entities identified including that of the consumers. The GIS technology adopted involves the use of computer based wares. A Hand-Held GPS was used in acquiring positional data. These data were formally integrated into computer based software for several analyses. The database generated contained information on the facilities and residential consumers. Series of spatial query operation was carried out to provide answer questions that lead to effective management and monitoring of the distribution facilities. Further analyses such as determining the trend/pattern of the rate in consumption of energy by the households within the study area were carried out. Areas of short-comings were identified and proposed locations/sites were generated in the service areas that needed new facilities. The end products are maps, tables and project report. It was however ascertained from the results that GIS is a competent and effective tool for managing/monitoring electricity distribution network. It also provides a better understanding towards effective distribution and conservation of electricity. In this context, the wrapping up shows that GIS makes map revision and digital mapping easier and some useful recommendations were proffered.
