Desenvolvimento e avaliação de um sistema piloto de microgeração hidroenergética na rede de abastecimento de água de Curitiba

Abstract

The energy scenario in Brazil requires the search for alternatives for power generation more efficient and sustainable way. In this context, the sanitation companies have locations and devices, like control valves, which have potential energy waste that water can offer. Thus, an solution to use that potential energy is the replacement of valves by an electric power microgeneration system, so that it can, yet, impose the pressure drop required in the supply network. Considering that the existing bibliography is limited to potential analysis and laboratory experiments, the objective of this final project is to develop a pilot project, implement it and evaluate it as its operation and the power that it will be able to produce. Therefore, the system must be composed of a pump working as a turbine and an asynchronous induction motor working as generator and self-excited by capacitors. Based on methodologies proposed by researchers of the field, criteria were established to choose the installation location, for your sizing and operational evaluation. Once properly sized the necessary equipment, an executive project was designed to implement the pilot system. With the installation of the system, power generation was obtained with acceptable voltage and electrical frequency by ANEEL’s standards, with power 17,83 kW and 54% of efficiency. The results obtained with the implementation of this study validate the methodology applied and prove that this is a viable alternative to energy use in water supply systems.
