Estudo de um sistema de aproveitamento da energia armazenada na frenagem regenerativa elétrica em elevadores

Abstract

Due to the current planet situation, caused by the aggression to the environment, the search to the sustainable development is constant. For this reason, new ideas and projects, that uses the electrical energy in a economic or rational way, are extremely valued. In this context, is also valued the projects executions, including, besides to the rationalization of energy use, the known alternatives sources, in the way to preserve the primary energy sources. Therewith this principle was verified the possibility to use the energy stored through the regenerative brake at elevators. The regenerative brake isn’t still a concept widely broadcast, however, through the storage of generated energy, is possible to carry out, among another processes, the engine start-up coupled in booster pumps. In this way, were realized studies and collections that led up the formulation of a solution, looking for the use, in booster pumps, of the generated energy of the regenerative brake. Furthermore, in reasons of evidences, an experiment was realized, simulating the system proposed in the better used of generated energy in the process of regenerative brake in elevators. The solution proposed includes a command and control system, in order to guarantee the water supply, even when the regenerative energy, from elevators, is insufficient to attend the demand of process of pumping water.
