Análisis de calidad y confiabilidad de la energía eléctrica en el IESS Hospital de Especialidades Carlos Andrade Marín

Abstract

In this work, a power quality and a reliability analysis of the Carlos Andrade Marín Hospital (HCAM) of the IESS, one of the Level 3 hospitals in the country, is achieved. The international standards and criteria of the European Committee for Standardization (EN 50160); the International Electrotechnical Commission (IEC 61000-3-2, IEC 61000-2-4, IEC 61000-4-30); the Institute of Electrical and Electronic Engineering (IEEE-1110, IEEE-1159, IEEE-519) and the country's Regulation and Control Agency (ARCONEL 005/18) are used for the study; The measurement point of the quality analysis is the output of the Linear Electron Accelerator and a FLUKE 435-II energy analyzer is used, because it allows to reduce downtime. The measurement period includes the days from July 22 to 30, 2019, satisfying the minimum required interval of 7 days given by the EN 50160 standard. Based on the results, grounding improvements are proposed, which will allow eliminating the problems of neutral conductor. Later, an analysis of the load distribution, the uninterruptible energy systems, UPS, and a reliability analysis based on the Zone- Branches reliability methodology in MATLAB are also performed. For this last analysis only the Nuclear Medicine area and the Central Block of the HCAM are considered, while for the previous ones all the hospital areas are considered. In addition, the equivalent system, of the Nuclear Medicine area and the Central Block in PowerFactory 15.1, is modeled to assess the current state of the transformers versus the expected state with the improved proposals. To complete this work, the acquisition of transient protection equipment such as TVSS, static compensators such as D-STATCOM and even the installation of a new lightning rod is proposed. All this comprehensive analysis will benefit the institution both economically and technically, by improving quality and reliability indices and reducing electrical system failures. Users will also benefit, being treated by a hospital that meets the technical standards of electrical energy quality.
