Impact of automation on enhancing energy quality in grid-connected photovoltaic systems

Virgilio Alfonso Murillo Rodríguez NOE VILLA VILLASEÑOR José Manuel Robles Solís OA Guirette-Barbosa (2023, [Artículo])

Rapid growth in the integration of new consumers into the electricity sector, particularly in the industrial sector, has necessitated better control of the electricity supply and of the users’ op-erating conditions to guarantee an adequate quality of service as well as the unregulated dis-turbances that have been generated in the electrical network that can cause significant failures, breakdowns and interruptions, causing considerable expenses and economic losses. This research examines the characteristics of electrical variations in equipment within a company in the industrial sector, analyzes the impact generated within the electrical system according to the need for operation in manufacturing systems, and proposes a new solution through automation of the regulation elements to maintain an optimal system quality and prevent damage and equipment failures while offering a cost-effective model. The proposed solution is evaluated through a reliable simulation in ETAP (Energy Systems Modeling, Analysis and Optimization) software, which emulates the interaction of control elements and simulates the design of electric flow equipment operation. The results demonstrate an improvement in system performance in the presence of disturbances when two automation schemes are applied as well as the exclusive operation of the capacitor bank, which improves the total system current fluctuations and improves the power factor from 85.83% to 93.42%. Such a scheme also improves the waveform in the main power system; another improvement result is when simultaneously operating the voltage and current filter together with the PV system, further improving the current fluctuations, improving the power factor from 85.83% to 94.81%, achieving better stability and improving the quality of the waveform in the main power grid.

Los mapas nunca se han dibujado solos. Desde Cipango hasta Santafé, pasando por la ciudad de México, la de Michoacán o barrios inadvertidos como Xocotitla, siempre han existido unos ojos para describir o medir los territorios. Entre las varas, millas, cartas de navegación, croquis o fuentes cartográficas no sólo hallamos distancias, sino también abismos culturales. En este libro los planos participan de una historia contextual: revelan tanto el horizonte cultural de quienes los elaboraron como de sus usuarios. Se muestran paisajes narrados, vividos y representados: desde las notas de Marco Polo a las rutas de Cristóbal Colón, hasta los proyectos futuristas irrealizados en Bogotá, pasando por la presencia de las trazas renacentistas en las urbes prehispánicas, la división por cuarteles o por el reparto de tierras comunales indígenas, todo nos invita aquí a compartir una apasionante reflexión sobre cómo se construye el pasado desde el mundo visual de los planos.

Development of a thermoelectric test for electrical contactors

PABLO OROZCO CORRAL FRANCISCO JAVIER IBARRA VILLEGAS NOE VILLA VILLASEÑOR (2023, [Artículo])

In the economic model in which we develop, there is a dependence on the means of transport that every day is increasing and due to the importance of electrification in the issue of efficient and clean transportation, has caused the need for companies supplying components for automotive manufacturers to evolve and develop new technologies to stay ahead of the needs of their customers being in full evolution towards electrified transport. This evolution extends not only to manufacturing but to the test methods that currently exist, since automotive standards require suppliers to test in laboratory, the components they sell to their customers to ensure their correct operation.

THE RIGHT TO THE CITY AND URBAN-RURAL LINKAGES. COMMUNITY PARTICIPATION IN THE METROPOLITAN AREA OF TUXTLA GUTIERREZ, CHIAPAS.

Briseida Corzo Rivera Gabriel Castañeda Nolasco (2023, [Artículo, Artículo])

Access to water is a common struggle of the communities in the state of Chiapas, with the effects of urban expansion these struggles increase and with them the challenges that these populations already face, having a greater impact on the rural environment. The struggles to satisfy this basic need are a factor that has triggered processes that promote community participation. Based on a qualitative analysis, this paper compares two existing forms of participation in the rural communities of the Metropolitan Area of Tuxtla Gutierrez that allow the population to manage actions to improve their quality of life. The objective is to analyze how these processes promote or restrict the empowerment of the community and allow progress, not only in the population's access to water, but also in the construction of the right to the city. From the urban-rural linkages, the right to the city is discussed beyond the city, addressing other territories. The study identifies factors that show changes in the participation of the populations and strengthen the community, as well as factors in the relationships of the community and of the community with other actors that limit the scope of the processes.

Structural analysis evaluationfor rollers of chassis dynoUsing finite element software

Jesús Emmanuel López Rizo ALFREDO CHAVEZ LUNA JAIME GONZALO SANTANA ESQUIVEL (2023, [Artículo])

This paper discusses the design considerations for a chassis dynamometer, focused on the rollers system used for measuring the power and torque of a vehicle in a university-level workshop. The design must prioritize factors such as safety, ease of use, adaptability to diverse types of vehicles, and the inclusion of safety systems to protect students and the vehicle. The work suggests adaptative features for the design, such as an adjustable fastening system and a compact and portable design, to adapt the structure into a university laboratory. The study also describes common methods for measuring engine power and torque using a chassis dynamometer, and the accurate and reliable measurement systems used for this purpose. This concludes with a discussion of the manufacturing methods used for the chassis dynamometer and a static analysis of the maximum effort capacity in each roller using Von Mises and Goodman fatigue theories. Developing a chassis dynamometer, in accordance the current patents available for workshop practices in a university is essential for providing students with comprehensive training.

Do provisioning ecosystem services change along gradients of increasing agricultural production?

Ronju Ahammad Stephanie Tomscha Sarah Gergel Frédéric Baudron Jean-Yves Duriaux Chavarría Samson Foli Dominic Rowland Josh Van Vianen Terence Sunderland (2024, [Artículo])

Context: Increasing agricultural production shapes the flow of ecosystem services (ES), including provisioning services that support the livelihoods and nutrition of people in tropical developing countries. Although our broad understanding of the social-ecological consequences of agricultural intensification is growing, how it impacts provisioning ES is still unknown. Objectives: We examined the household use of provisioning ES across a gradient of increasing agricultural production in seven tropical countries (Bangladesh, Burkina Faso, Cameroon, Ethiopia, Indonesia, Nicaragua and Zambia). We answered two overarching questions: (1) does the use of provisioning ES differ along gradients of agriculture production ranging from zones of subsistence to moderate and to high agriculture production? and (2) are there synergies and/or trade-offs within and among groups of ES within these zones? Methods: Using structured surveys, we asked 1900 households about their assets, livestock, crops, and collection of forest products. These questions allowed us to assess the number of provisioning ES households used, and whether the ES used are functionally substitutable (i.e., used similarly for nutrition, material, and energy). Finally, we explored synergies and trade-offs among household use of provisioning ES. Results: As agricultural production increased, provisioning ES declined both in total number and in different functional groups used. We found more severe decreases in ES for relatively poorer households. Within the functional groups of ES, synergistic relationships were more often found than trade-offs in all zones, including significant synergies among livestock products (dairy, eggs, meat) and fruits. Conclusions: Considering landscape context provides opportunities to enhance synergies among provisioning services for households, supporting resilient food systems and human well-being.

Este trabajo refiere a la historia de San Francisco Xocotitla, un antiguo pueblo indígena, actualmente ubicado en la alcaldía Azcapotzalco, en la Ciudad de México. Su documentación remite a una de las dos parcialidades en que quedaron asentados los barrios de indios luego de la fundación novohispana de la Ciudad de México. San Francisco Xocotitla – también denominado San Francisco Xocotitlán o simplemente Xocotitla– ocupó un extremo de la parcialidad de Santiago Tlatelolco, al noroeste de la urbe. Su historia y transformaciones espaciales se vinculan al pasado de Azcapotzalco, una jurisdicción ampliamente investigada. Aunque escasos, los escritos y planos sobre esos poblados ignorados por la historia, añaden información sobre cómo se desenvolvieron ante los sucesivos reordenamientos urbanos. Esas imágenes invitan a reconocer distintas maneras de comprender aquel mundo.
