Abstract

The interruption of the energy from the Public Grid, RPEE, is a constant threat for small, medium and large consumers. The simple acquisition of a generator with a motor does not do away with the threat of interruption of supply. The submitted project aims to effect the automatic switching on/off of a generator and also carry out the automatic changeover between the energy coming from the Grid (RPEE) and the energy produced by the generator to meet a demand. The hardware was conceived to be easily installed in various pieces of equipment existing on the market. Besides this, the project implements two more innovative functions. The first concerns the monitoring and remote access for the diagnosis, prevention and alarm in generator failures, allowing for the automation of the preventative maintenance of failures in the generator park installed in the field. The second function concerns the intelligence of the selection of loads in response to requested demands. The project proposes that the control and activating functions of the generator motor and the electro-mechanical or electronic change-over of energy between the Grid and the generator be implemented by a proprietary application- specific integrated circuit (ASIC). Other functions (for example, remote communication) should be carried out by commercial circuits, among them microprocessors. (AU)
