Electrical power density calculation for public street lighting in the city of Cuenca

Abstract

The trend of the world today is oriented to the search for systems that consider a rational and efficient use of energy, where resources are used to the maximum, maintaining the quality of goods and services. The public lighting system is not exempt from this reality being necessary to evaluate it under an energy efficiency indicator that allows us to know if an adequate use of energy is available. The indicator used in this work is the Density of Power for Street Lighting (DPEA) proposed by the Technical Regulation of Lighting and Public Lighting (RETILAP), this indicator considers the total load connected for lighting and the total area illuminated in meters Squares (W/m²).

The main objective of this work is to present a summary of the calculation of the DPEA for the road network of the city of Cuenca and based on this, to identify the ways that comply with this criterion. In order to achieve this objective, a measurement of the parameters necessary for the calculation of the DPEA was carried out and in this way to present the pathways that use energy efficiently. With the information obtained, a minimum DPEA was also established that allows to know if the roads are correctly illuminated, however, given the different conditions under which the measurements were made, the results must be analyzed and contrasted in future research.
