Two such tele-experiments are described which best comply with the objectives of case of use, student/tutor interaction, on-site viewing, real-time operation and safety against modifications. The first set-up is an intelligent inverter drive experiment using the Linux operating system and VNC as Internet access software. Both are cost-free. Linux offers the possibility to restrict access to certain applications, thus making it very safe with respect to system modifications, deliberate or nondeliberate. VNC provides a remote display system allowing the viewer to view a computing desktop environment from anywhere on the Internet. In order to interface with the tutor or other clients, a text editor, Pico, is installed. Since control of the experiment is done via RS232 serial link, Minicom is set up within VNC. The second set-up is a DC motor experiment using Windows98 operating system. Matlab/Simulink is used first to simulate and optimise the performance of the motor in a control loop. After achieving satisfactory results, the simulated motor is replaced by real hardware in the lab via the Internet using Real-Link/32. A microphone and web-camera is installed to provide audio/video feedback of the action of the motor.","PeriodicalId":215475,"journal":{"name":"11th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

El-Debeiky","doi":"10.1109/MELECON.2002.1014623","DOIUrl":"https://doi.org/10.1109/MELECON.2002.1014623","url":null,"abstract":"The electric utility planning process begins with the electric load forecasting, because of the advanced need for new utility plants. These long lead times require the utility planning horizon to be at least ten years long. Since utility decisions involve an economic analysis of the operating and investment costs, the utility planning horizon may range from fifteen to thirty years into the future. Forecasting load demand is a difficult procedure and combines art with science. The key contribution of forecasters is their knowledge of electricity consumers and an understanding of the way they use electricity and other competing energy forms. The problem gains special aspects in developing countries, such as Egypt, because of the high demand growth rate as well as the wide differences in the modes and levels of consumption in the various regions (governorates) in the country. In this study, several structures for neural networks are proposed and tested. They proved to perform as one of the best and most sophisticated load forecasting systems. In this study, the case of a number of neurons layers equal to 7 gives the best results with high accuracy with the least error. The forecasted peak loads and light loads, up to year 2010, for the six Regions of the Egyptian Unified Network; Alexandria, Delta, Cairo, North Upper Egypt, South Upper Egypt and the Canal, are obtained directly from one case by using actual and practical past ten years data.","PeriodicalId":215475,"journal":{"name":"11th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.
