In the light of this stark reality of a country like Nigeria which is constantly plunged into pitch darkness all year round, it has become expedient for a sustainable and urgent remedy to be sought if our country will ever think of rubbing shoulders with the economies of the world. It is this pathetic scenario, we find ourselves in that it has given rise to this paper which tends to review possible ways and means of redressing the ugly trend. This paper examines the prospects and possible applications of Smart Grid Technology (SGT) to the Nigeria Power System. Nigeria Power System consists of 28 buses, 32 Transmission lines and 10 generating stations, with a view to reduce the high active and reactive transmission losses. The study shows that smart grid system will make the present network more efficient and reliable by connecting different sources of distributed generators into the existing grid. Basic requirements necessary for the application of SGT using the Nigeria Power System as a case study were discussed.展开更多

Parameters measured include supply voltage, stator coli temperature and casing temperature. For the temperatures of both stator and casing, temperature sensors were used. The sensor senses the temperature and sends its output to the analogue to the digital integrated circuit for further processing. The supply voltage is also moni-tored by a circuit and integrated circuit. The project on completion was tested and the parameters displayed on the portable computer. The objectives of the project are: The supply system can measure the following parameters: supply voltage, stator coil temperature, casing temperature. Display the data on the PC screen with the possibility of settings to establish range, limits and alarm indicators when these are exceeded. The program should be able to save data of the log entry with time on a dedicated file as record for future analysis.展开更多
