Reliability, availability, and condition monitoring of inverters of grid‐connected solar photovoltaic systems

Reliability, Availability and Condition Monitoring (RACM) evaluation has become a critical area of interest for researchers as the output power quality Photo-Voltaic (PV) system depend on reliability its components. In this paper, RACM grid-connected PV systems is presented. For this, Reliability Block Diagram (RBD) technique along with exponential probability distribution function used. The main objective work to identify weakest subsystem in order enhance reliability. condition monitoring will be helpful avoiding sudden breakdown unexpected maintenance system. An elaborate analysis presented beginning from sub-assemblies subsystems then overall addition, are ranked based their impact availability This decided importance measures. It observed that inverter forms solar novelty proposed method one can monitor health status or useful life regularly which not yet explored literature. Most papers have considered components non-repairable but redundancy concept helps increasing When results obtained compared existing methods, it discovered outperforms them.
