Optimização da matriz de iluminação pública na estrada circular de Maputo no troço Zimpeto - Albazine

Abstract

Rationalizing electricity consumption has been a priority almost everywhere in the world, and Mozambique is no different. One of the most viable alternatives for achieving this goal is the use of highly energy-efficient electrical devices. The method described above can be combined with renewable energy sources in order to achieve further gains. This project is the result of a study carried out on Maputo's ring road on the Zimpeto - Albazine section, with a view to optimizing the public lighting matrix on this stretch of road, where it was concluded that it is possible to save around two thirds of the energy that is spent at the moment when the public lighting matrix is based on VSAP lamps connected to the public network. From the study carried out, and with a view to rationalizing electricity consumption in the IP network, the use of a photovoltaic system combined with 70W LED lamps was defined as an alternative. The new IP array on this stretch of road adopts an OFF-GRID system. The first step was to carry out a load survey, followed by an economic study of the IP array with VSAP lamps, after which all the components of the new array were sized. The project ended with a financial impact study.
