【摘要】：随着电力电子技术在新能源、高速机车、直流输电等大容量电力变换领域的广泛应用,其可靠性问题成为学术界和工业界的研究热点。基于因果模型的可靠性分析方法虽然在研究早期提供了原理层面的阐述,但在多物理场强耦合的复杂工况中的应用价值较低,而基于数据模型的可靠性研究方法尚处于初级阶段。该文提出将大数据处理技术应用于大容量电力电子系统可靠性研究的新思路,充分借助电力变换装置的海量历史运行数据,引入机器学习、数据挖掘和人工智能等大数据科学的最新理论成果,从数据泛在关系出发开展可靠性研究。论文详细阐述电力电子系统的大数据特征,并总结电力电子系统大数据应用中的若干关键技术。此外,论文从器件装置系统等多个层面深入分析大数据处理技术在大容量电力电子系统可靠性研究领域的潜在应用。大数据基本理论和方法的应用将提供一种通过数据关系间接理解原理本质的研究方法论的思维转变,有望为电力电子系统的可靠性研究开辟新途径。
[Abstract]:With the wide application of power electronics technology in new energy sources, high-speed locomotives, direct current transmission and other large capacity power conversion fields, Although the reliability analysis method based on causality model provided the explanation of the principle in the early stage of the research, the application value of the reliability analysis method in the complex condition of multi-physical field intensity coupling is low. However, the reliability research method based on data model is still in its infancy. In this paper, a new idea of applying big data processing technology to the reliability research of large capacity power electronic system is put forward, which makes full use of the massive historical operation data of power conversion device. By introducing the latest theoretical achievements of big data science, such as machine learning, data mining and artificial intelligence, the reliability research is carried out from the point of view of data flooding. Some key technologies in the application of big data in power electronics system are summarized. In this paper, the potential application of big data processing technology in reliability research of large capacity power electronic system is analyzed from several aspects, such as device / device system and so on. The application of basic theory and method of big data will provide a kind of. The change of thinking in the methodology of understanding the essence of principle indirectly through data relations, It is expected to open a new way for the reliability research of power electronic system.
