Guia técnico 3 — Alimentação de energia

Conhecer os procedimentos envolvidos no abastecimento de energia é de vital importância e é por essa razão que o tema é abordado neste terceiro guia técnico. Explica-se esta abordagem de forma totalmente qualitativa, complementando o segunda guia, por forma a lograr eficiência energética através de uma operação analítica da alimentação de energia.

Electrical energy supply 03 Power guide 2009 / book 03 INTRO The convergence of physical means, established rules and shared procedures ensures the provision of safe, abundant and high quality electricity. Everyone understands the need to improve this level of service, but its underlying complexity calls for serious consideration: distribution systems, equipment and infrastructures, neutral earthing systems, controlling disturbance, power factor compensation, etc. are just a few of the essential subjects. The production, transmission, control and protection of electricity (from distribution systems through to the terminal connection of receivers, and including the transformation, metering and distribution stages) must be carried out in a totally safe way, taking care not to pollute it (which is a new aspect). Electricity is a shared commodity that must be protected just like air or water. It is therefore important to avoid using it indiscriminately and discharging all types of disturbance onto the system. Deterioration of the power factor, harmonics, transients, etc. have a harmful effect on the signal and disadvantage all users. The quality of energy is now controlled by strict standards, but these will doubtless have to change further to control aspects of electromagnetic compatibility that are constantly changing with the introduction of new production technologies (wind-powered, solar, etc.) or operating technologies (power electronics, DC, etc.) The solutions offered...
