摘要
构建合理的谐波源模型有助于深入分析谐波源机理、准确评估接入影响,指导谐波问题的治理。首先将现有谐波源建模方法分为基于机理分析的方法、基于概率统计的方法和基于机器学习的方法,并以此为出发点归纳总结了现有的谐波源模型及其应用场景。其次,阐述了新型电力系统中的超高次谐波现象、次同步谐振现象以及谐波耦合交互现象,指出现有谐波源模型在相关方面的研究仍需深入,并讨论了模型理论研究的工程化应用以及模型的评价机制。最后,指出谐波源模型高频化模型的进一步研究、机器学习在建模领域的深度应用以及谐波源模型在其他领域的应用是未来研究的发展趋势。
Building a reasonable harmonic source model is helpful to analyze the mechanism of harmonic source,accurately evaluate the impact of integration,and guide the governance of harmonic problems. In this paper,the existing harmonic source modeling methods are divided into mechanism-based method,probabilistic and statistical method,and machine learning method. On this basis,the existing harmonic source models and their application scenarios are summarized. Then,the phenomena of supraharmonics,subsynchronous resonance and harmonic coupling interaction in the novel power system are described,and it is pointed out that the study of the existing harmonic source models in related aspect is still needed. Afterwards,the engineering applications of the model theory and the evaluation mechanism of the model are discussed. Finally,the trends of future research are predicted,including high-frequency harmonic source model,deep applications of machine learning in the modeling field,and the application of harmonic source model in other fields.
