Based on the adaptive interference canceling theory and the concept of space vector , an adaptive fundamental positive / negative sequence component and harmonic component detecting method is developed . due to the close loop structure , this method has quite good robustness , and can meet the requirement of the asymmetrical control of hvdc - vsc well 運(yùn)用自適應(yīng)干擾對消原理和空間矢量的概念,提出了一種基波正序分量、基波負(fù)序分量及諧波分量的自適應(yīng)檢測方法,并進(jìn)行了詳細(xì)的理論分析,為研究hvdc - vsc的不對稱運(yùn)行控制奠定了基礎(chǔ)。
Based on the concept of space vector , an open loop detecting method for the fundamental negative and positive sequence components as well as the harmonic components is developed , which combining the conventional detecting method based on filters and the concept of space vector . this method can overcome the defaults of the conventional detecting method , and can meet the requirement of the asymmetrical control of hvdc - vsc 基于空間矢量的概念,提出了一種開環(huán)的基波正序分量、基波負(fù)序分量及諧波分量的實(shí)時(shí)檢測方法,這種方法可以看作是空間矢量的概念與傳統(tǒng)的基于濾波器的諧波檢測方法的結(jié)合,它能夠克服原有的基于濾波器的檢測方法的不足,可用于hvdc - vsc的不對稱運(yùn)行控制。
