PROPOSAL FOR A MANAGEMENT PLAN FOR THE MAINTENANCE OF THE ELECTRICAL ENERGY BACKUP SYSTEM OF THE PORTOVIEJO SPECIALTY HOSPITAL

Abstract

In the health sector, the quality and safety of the electricity supply play a very important role in the operation of hospitals and clinics. One of the fundamental aspects for the proper functioning of any type of hospital facility is the management of the electrical system, today it is more important than ever to design and operate electrical systems that not only have the maximum practicable efficiency, but also have the highest degree of security and reliability. But beyond this, special attention must be paid not only to the continuous supply of energy but also to its quality, referring to the distortions that may be present in terms of voltage or frequency variations. To guarantee proper operation, health centers must have an energy backup system that guarantees that electricity will not be affected or interrupted despite failures that may occur. In this study, the Portoviejo Specialty Hospital was taken as the research context, where qualitative, semi-quantitative and quantitative audits were carried out, to stage the maintenance problem in the electrical backup system. Taking into account that the electric power backup unit is made up of Generators and UPS, a criticality analysis was carried out on each one of them, analyzing various parameters, with the aim of finding the highly critical equipment and proceeding to evaluate them in addition to determine the maintenance tasks for each of them, considering the existing problems in the electrical system, where failures or stoppages in the generation system can occur at unexpected times. In the criticality analysis of the UPS, 5 components were obtained in a Critical state with ranges of 133.33 < Score ≤ 200; 5 teams were obtained in regular or Semi-Critical status with values ​​of 82, 87, 116 and 123 located in the range of 66.66 < Score ≤ 133.33. And 8 components were obtained in Non-Critical status with a value of 33, 58, 66 which are located within the range 6 ≤ Score ≤ 66.66. Likewise Based on the criteria evaluated in the criticality analysis, 5 components were obtained in Critical status with ranges of 136 and 156, located in the margin 133.33 < Score ≤ 200; 5 teams were obtained in regular or Semi-Critical status with values ​​of 99, 111, 126 and 123, located in the range of 66.66 < Score ≤ 133.33. And 2 components were obtained in a Non-Critical state with a value of 34 and 42, which is located within the range 6 ≤ Score ≤ 66.66. We understand as operations or critical loads everything that implies the continuity of the life of patients such as: operating rooms or intensive care, emergencies, laboratories, nursing stations, radiology, water treatment and vital medical equipment or systems, among others. In the case of normal operation, if there is a fault, the cut must not be greater than 60 seconds and for critical loads, the lack of energy cannot exceed 10 seconds, that is, the backup acts immediately when it comes to saving a person's life. The use of the Criticality analysis in the Hospital's Energy Backup System allowed us to make the right decisions and focus on the UPS and Generator equipment that is most critical, for which an FMEA was applied to both generators and UPS, with the aim of in order to perform better management to maximize its availability, maintainability and reliability.
