| description | Abstract This paper investigates the application of time-based fault tolerance techniques in solar photovoltaic (PV), DC–DC converter, battery, and permanent magnet synchronous motor (PMSM) systems. The fault tolerance techniques are like open circuit switch-level, leg-level, module-level, and measurement-level. By leveraging time-based monitoring and analysis, these techniques enable early detection, isolation, and recovery from various faults, enhancing system reliability and availability. The study focuses on fault scenarios within the 0.15–0.3 time per/second frame, a critical window for rapid fault response. Specific techniques, including time-based fault detection, isolation, and recovery strategies are explored in detail. The OPAL-RT HIL testing platform is used to validate the simulation results and conduct tests to evaluate the efficiency of various methods. The results demonstrate the performance of the fault-tolerant systems and the implementation of effective time-based techniques in solar PV applications. Finally, this work can be useful for researchers who want to learn how solar PV systems, batteries, and PMSM systems behave in fault situations followed by the conclusion. |
