The objectives in the background may pursue different approaches when determining the optimum or mostly recommended percentage. The present work focuses on determining relevant technical and economic criteria that allow the definition of adequate wind penetration rates. In particular, a methodology is used that aims to obtain these percentages for this energy source, and renewable in general. In order to evaluate the methodology, the case of the Argentine Electrical System is analyzed for different degrees of penetration of wind power generation (one of the most preponderant resources), with the purpose of finding the optimum target value that is possible to reach in the definition of The planning of the short, medium and long term operation. The present work is the second of two articles, and the methodology described in the first one of “Criteria for determining the percentage of large-scale wind energy to interconnected systems — Part I: Methodology Proposal” is used.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121202700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such saving was achieved through an automated system of blinds or curtains that allow the entrance of natural light into a room of a building. The paper discusses the advantages of using an automated system in comparison to a conventional or mechanical one. The prototype system makes use of a logical and electromechanical architecture for its operation. The automation of this system seeks to maintain a level of comfort and adequate lighting based on the Mexican normative (NOM-025-STPS-2008) of the Ministry of Labor and Social Welfare. The system has three operating modes: manual, automatic, and programmed. In manual mode, the user can adjust the level (height) of the blinds according to a specific need. In the automatic mode, the user establishes a required set point of illumination and, through a photo-resistance module, the system seeks to reach such illumination level. In the programmed mode and upon the use of a calendar, the user decides the opening percentage of the blinds throughout the day and the week. In this paper, energy and emissions have been calculated based on the 2017 Mexican energy mix.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121854061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper shows efficiency optimization of IMD using interior point method (IPM) and direct vector control (DVC) in order to adjust rotor flux, magnetizing current and torque current magnitudes. Therefore efficiency is the objective function to be maximized which consists of the mechanical power (output power) and the input power (output power plus losses). The losses which are taken into account are: switching and conduction losses, in the inverter and stator copper, rotor copper, core, windage and stray losses of the induction motor; all of them in function of slip. At steady state the IPM looks for an slip which minimizes the losses or maximizes the efficiency, once the slip is known, the rotor flux is calculated and given as a reference of the PI flux regulator in the vector control. The parameters which are given to the IPM are the estimated torque and reference mechanical speed. Finally, the efficiency optimization has been simulated in Python and the vector control system with optimum rotor flux has been simulated in Matlab Simulink®.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129282601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing cross-arm materials such as wood, steel and fiber reinforced polymer (FRP) are showing signs of deterioration. In some cases, these cross-arm materials can be extremely heavy and difficult to handle or transport into remote access line locations. The Totally Insulated Framing (TIF) Systems recently developed offer a new approach when replacing the traditional cross-arm designs. The new TIF systems overcome the disadvantages of cross-arms, they are lightweight and provide benefits that include increased framing life cycle and improved safety. The new designs can also offer increased vertical ground clearances, allow use of shorter poles or increased power line operating capacity while also reducing Right-Of-Way (ROW) width requirements. Many utilities involved in extensive transmission line cross-arm replacements find it necessary to conduct this work using live line methods. Line crews are discovering that the equipment available to support the conductors during the change out have mechanical strength and other limitations. The recently introduced K-ARM system was developed to overcome these restrictions efficiently, effectively and safely. These live line “tool kits” offers advantages previously unavailable with other alternative equipment.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124456931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El acceso al internet demanda que los campus se interconecten administrando una única conexión a internet a través de un proveedor del servicio de forma local. El flujo de información entre las sedes requiere de una red de comunicaciones que permita el flujo de información a altas velocidades, lo que viene a configurar una red de respaldo para la red física con la que opera actualmente la Universidad. La tecnología FSO permite realizar configurar un enlace propietario, autónomo y de gran velocidad para que la Universidad pueda tener un sistema redundante de comunicaciones, además con la implementación de la red FSO permitirá el ahorro de recursos al no tener que contratar un canal dedicado con un permisionario de servicio portador de telecomunicaciones para la interconexión de las sedes de la UDLA.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133892188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
