“…Based on this behavior of the electrical power demand, the energy consumption in both conditions was calculated, as well as the energy losses when the TIM was powered by the PVS, applying equations ( 6), (7), and (8) as proposed by (Angarita et al, 2019). Egrid represents the energy consumed by the TIM when powered by the electric grid, expressed in watts (W).…”

This study aims to determine the energy efficiency of three-phase induction motors (TIM) powered when operated with photovoltaic systems (PVS). The environmental advantages of photovoltaic systems (PVS) are very well known. However, there are still challenges related to energy quality, electricity generation instability, failure in frequency regulation, instability in reactive power, and harmonics generation. However, the impact of PVS on TIM efficiency has not been thoroughly explored. This research compares a TIM's electromechanical characteristics and efficiency when powered by a conventional electrical grid versus a PVS. Experimental studies revealed that when powered by the PVS, the TIM experienced increased voltage and higher voltage and current harmonics compared to grid power. These electrical difficulties, attributed to the PVS inverter, resulted in a 2.7% decrease in TIM efficiency compared to grid power. Modeling conducted under actual load variation conditions demonstrated a 2.6% increase in energy consumption when powered by the PVS compared to grid power. Based on these findings, PVS installers are advised to consider the energy quality provided by these systems, as it may affect the efficient operation of TIM, leading to increased energy consumption.

“…They are a systematic documented procedure with the objective on minimize energy costs., without affecting production and quality by defining objectives, policies and procedures that will be are maintained and improved (Schulze et al, 2016;Kanneganti et al, 2017). ISO 50001, supports the guidelines to develop an EnMS, based in a flexible framework that allow companies to integrate energy efficiency systems into their management practices (Angarita et al, 2019). The model covers four steps: energy policy, energy Source: Prepared by the authors based on data from: (Benedetti et al, 2018;Šešlija et al, 2011;Saidur et al, 2010;UPME, 2013;UPME, 2014;UPME, 2014 planning, implementation and checking, based on de Deming Cycle (Plan-Do-Check-Act), all of them are incorporated into a continuous improvement cycle as is shown in Figure 2 ( Gopalakrishnan et al, 2014;ISO 50001, 2011;Correa et al, 2014).…”

Compressed air is one of the most widely used application energies in the industry, such as good transportability, safety, purity, cleanliness, storage capacity and ease of use. In many countries, compressed air systems account for approximately 10% of the industry's total electricity consumption. Despite all its advantages, compressed air is expensive, only between 10% and 30% of the energy consumed reaches the point of final use. Energy is lost as heat, leaks, pressure drop, misuse, among others. Energy efficiency measures such as: reducing compressor pressure, lowering air inlet temperature, adequate storage capacity, recovering residual heat from the air compressor and reducing leakage, can produce energy savings between 20% and 60%, with an average return on investment lower than 2 years. This paper analyzes the main energy efficiency measures that can be applied in the CASs, the potential energy savings, implementation costs and return rate of each of them are being calculated giving a necessary tool for companies in their objectives to reduce greenhouse gas emissions and energy consumption.

El presente trabajo se trazó como objetivo realizar una caracterización energética en la Empresa de Mantenimiento a Grupos Electrógenos Fuel Oil de Pinar del Río, Cuba donde se detectó un elevado consumo de portadores energético en los motogeneradores Hyundai HIMSEM 9H25/33S. Se aplicaron herramientas matemáticas propuestas en la bibliografía acordes a este tipo de estudios (Diagrama de Pareto, Pruebas de Normalidad, Histogramas, entre otras). Los datos recolectados referentes al consumo de combustibles, lubricantes, agua y electricidad se procesaron mediante el software SPSS y una hoja de cálculo en Microsoft Excel. Se identifica como puestos clave la nave de motores, lugar donde se concentra el conjunto de equipos que consumen más del 80 % de portadores energéticos, siendo el Fuelóleo y Diesel los más representativos. Dentro de los equipos claves destaca el caso del Motor 7 pues presenta un bajo consumo en Toneladas Equivalentes de Petróleo (TEP), sin embargo, al estimar aproximadamente el consumo por hora se aprecia que presenta un valor de 5.85 TEP, el cual es muy superior a los demás motores que ronda una media de 2.91 TEP. Se concluye que la empresa debe seguir trabajando en el control sistemático del uso final de energía; aumentar la superación técnica de los operarios y responsables de áreas, además, durante el año 2021 el índice de consumo de combustible se comportó de manera homogénea, presentando poca variabilidad, pero se demostró que la media de la muestra de índice de consumo difiere de lo estipulado por el fabricante.
