Arquitectura Tecnológica para la digitalización de datos y obtención de KPIs aplicados a la Calidad de Energía y Eficiencia Energética en Generadores Marinos

Abstract

Abstract: This research aims to design a technological architecture for the digitalization of operational data and the generation of key performance indicators (KPIs) aimed at evaluating power quality and energy efficiency in marine generators. The study was applied to a power generation system based on Yanmar 6N21LV engines, with the purpose of transforming operational electrical variables into meaningful information to support the energy management of the vessel. The proposed architecture is structured into four functional layers: measurement and data capture, communication and data acquisition, information processing, and visualization for decision support. At the field level, electrical measurement devices register operational variables such as active power, voltage, current, frequency, and power quality parameters. Data are acquired through Modbus RTU communication over an RS-485 interface and processed using energy models implemented in software, including interpolation algorithms based on the manufacturer s specific fuel consumption (SFC) curves. The findings confirm that the digitalization of electrical data combined with energy performance KPIs significantly improves the visibility of generator operational efficiency and provides a technical foundation for optimizing energy management, reducing fuel consumption, and supporting decision-making processes in marine power generation systems.
