Implementação de um sistema fotovoltaico híbrido com anti-ilhamento

Abstract

The usage of photovoltaic systems has been growing exponentially in the last years, due became a more accessible system, highly spread and it takes an average of five years to be self-paid. Due to the current standards, it is possible to insert the excess of electrical energy produced by the panels in the electrical net, bringing credits as a benefit, and they may become discounts in the electric energy bill. But, when a blackout occurs, the system stops the operation of the consumer unit of working with photovoltaic energy, in order to prevent eventual accidents caused by having the electrical network energized. So, when a blackout occurs all the energy produced by the photovoltaic system would be wasted, because it cannot be stored and neither be consumed. Therefore, the goal of this study is developing a photovoltaic system that has a battery bank and an anti-islanding system, this system must detect a failure in the electric net and still be able to feed the consumer unit with the energy stored in the battery bank, with no contact with the electric net.
