Abstract
La finalidad de este trabajo es ofrecer una mejora al plan de mantenimiento de plantas fotovoltaicas PMGD dependiendo de la zona de Chile donde se encuentran localizadas. Se utiliza como base la revisión del histórico de fallas de siete plantas fotovoltaicas PMGDs distribuidas a lo largo de diversas regiones de Chile.
El proceso se inicia con un análisis taxonómico que hace evidente la complejidad de un sistema fotovoltaico. Luego se procede al estudio de modos y tasas de falla que afectan a los subsistemas de equipos que componen el sistema fotovoltaico. Estos resultados, en conjunto, constituyen un análisis de criticidad desarrollado mediante la aplicación de una matriz de criticidad, que tiene como objetivo identificar cuál de los subsistemas de un parque fotovoltaico PMGD presenta el nivel más elevado de criticidad al momento de fallar.
Una vez establecido el componente crítico, se lleva a cabo un análisis detallado empleando la técnica FMECA y se determinan los agentes climáticos que contribuyen con mayor probabilidad a la ocurrencia de fallas de alto y muy alto riesgo en el componente crítico. Los resultados de este análisis se traducen en una propuesta de mejora para el plan de mantenimiento existente. El objetivo primordial de esta propuesta es reducir la incidencia de fallas críticas, y dicha estrategia se adapta según la zona geográfica en que se encuentre ubicado el proyecto fotovoltaico.
The purpose of this work is to provide an enhancement to the maintenance plan of PMGD photovoltaic plants depending on the region of Chile where they are located. The historical failure records of seven PMGD photovoltaic plants distributed across various regions of Chile serve as the basis for this study. The process begins with a taxonomic analysis that highlights the complexity of a photovoltaic system. Subsequently, an analysis of failure modes and rates affecting the subsystems of equipment composing the photovoltaic system is conducted. These results collectively form a criticality analysis developed through the application of a criticality matrix, aimed at identifying which subsystem of a PMGD photovoltaic plant exhibits the highest level of criticality at the time of failure. Once the critical component is identified, a detailed analysis is carried out using the FMECA technique, determining the climatic agents that contribute most likely to the occurrence of high and very high-risk failures in the critical component. The results of this analysis translate into a proposal to enhance the existing maintenance plan. The primary objective of this proposal is to reduce the incidence of critical failures, and this strategy is adapted according to the geographical zone in which the photovoltaic project is located.
