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.

基于时基容错技术的太阳能光伏系统可靠性改进设计与实现。

本文研究了基于时间的容错技术在太阳能光伏（PV）、DC-DC变换器、电池和永磁同步电机（PMSM）系统中的应用。容错技术有开路开关级、支路级、模块级和测量级。通过利用基于时间的监控和分析，这些技术可以实现早期检测、隔离和从各种故障中恢复，从而增强系统的可靠性和可用性。研究的重点是0.15-0.3秒帧内的故障场景，这是快速故障响应的关键窗口。详细探讨了具体技术，包括基于时间的故障检测、隔离和恢复策略。利用OPAL-RT HIL测试平台对仿真结果进行验证，并对各种方法的有效性进行测试。结果证明了容错系统的性能和有效的基于时间的技术在太阳能光伏应用中的实现。最后，这项工作对于想要了解太阳能光伏系统、电池和PMSM系统在故障情况下的行为的研究人员是有用的。
