论文摘要
电力电子转换器已被广泛用于航空航天系统，直流传输，分布式能源，智能电网等，电源电子转换器的可靠性一直是学术界和行业的热点。执行电力电子转换器开放电路故障和智能故障诊断以避免次要故障，减少操作和维护成本，并提高电力电子系统的可靠性，这一点很重要。首先，分析和总结电力电子转换器的故障特征。其次，对电源电子转换器中的一些基于AI的故障诊断方法和应用示例进行了审查，并提出了基于随机森林和瞬态故障特征的故障诊断方法，用于三相功率电子转换器。最后，指出了未来的研究挑战和基于AI的故障诊断方法的方向。
Power electronics converters have been widely used in aerospace system, DC transmission, distributed energy, smart grid and so forth, and the reliability of power electronics converters has been a hotspot in academia and industry. It is of great significance to carry out power electronics converters open-circuit faults monitoring and intelligent fault diagnosis to avoid secondary faults, reduce time and cost of operation and maintenance, and improve the reliability of power electronics system. Firstly, the faults features of power electronic converters are analyzed and summarized. Secondly, some AI-based fault diagnosis methods and application examples in power electronics converters are reviewed, and a fault diagnosis method based on the combination of random forests and transient fault features is proposed for three-phase power electronics converters. Finally, the future research challenges and directions of AI-based fault diagnosis methods are pointed out.
