Future work will focus on detecting other types of faults in grid-tied NPC inverters, thereby enhancing the comprehensiveness and applicability of fault detection strategies in grid-connected converters. The authors declare no conflicts of interest.
An ANN based FDL employing DWT based fault feature mining for grid connected PV inverters is proposed, which incorporates thermal overstress and wear out failures in IGBTs using MATLAB/PLECS integration. This work develops two classifiers, which are able to work in both component failure and degradation conditions.
System behavior is analyzed for parameter identification and anomaly detection. Based on this system behavior, the information obtained can be utilized for real-time or online health monitoring (OHM) . To ensure improved reliability, FDL techniques are employed in grid connected PV systems.
Figure 19 presents an image of the real-time experimental setup where MATLAB was used for the MPC with fault detection and inverter models. In this setup, two real-time systems with identical characteristics are used. The grid-connected three-phase NPC is initially modeled on a personal computer using MATLAB.
