摘要 ：了新的術(shù)語，明確了對(duì)稱與諧波成分的關(guān)系。三相對(duì)稱集和不對(duì)稱集集合的分類。子介紹，名稱分別為對(duì)稱平衡臺(tái)，套對(duì)稱不平衡，不對(duì)稱平衡集和不平衡不對(duì)稱套表明，三相集可以解決的任何一個(gè)，兩個(gè)或三個(gè)對(duì)稱組件集。從四個(gè)案例研究的結(jié)果表明，這些子類和他們的解釋的對(duì)稱分量有助于理解有諧波分析的系統(tǒng)平衡和不平衡諧波源和負(fù)載。
關(guān)鍵字：非對(duì)稱集;諧波流動(dòng);諧波源;對(duì)稱分量套;對(duì)稱套。
任何周期波的形狀可以分解成或作為基波和諧波一系列的分析。
三相諧波分析，需要對(duì)諧波源之間，對(duì)稱分量輸入關(guān)系有清楚的了解（如調(diào)速，ASD負(fù)載）及其關(guān)系（對(duì)稱分量）從一個(gè)諧波源應(yīng)用程序所產(chǎn)生的線性系統(tǒng)諧波流動(dòng)。
引用數(shù)量有限的簡(jiǎn)要信息包含關(guān)于諧波及對(duì)稱分量。參考文獻(xiàn)1，提供了關(guān)于這一主題的段落，并使用與諧波及標(biāo)題'關(guān)系對(duì)稱分量'。它包括一個(gè)由一個(gè)簡(jiǎn)短的解釋性段落，支持表。表中的術(shù)語表達(dá)了積極的諧波，負(fù)，零序列。這些序列在平衡的三相系統(tǒng)諧波。指的標(biāo)題，而對(duì)稱的部分內(nèi)容是指平衡三相系統(tǒng)。這就是異常。從本質(zhì)上講，（特別是埃羅序列）對(duì)稱分量只適用于非平衡系統(tǒng)。下面的問題閱讀一段后參考。
(a) 是否對(duì)稱分量（特別是零序）在傳統(tǒng)意義上，適用于均衡和不平衡非正弦系統(tǒng)，這是從打破傳統(tǒng)？
(b) 什么條件，對(duì)稱，非對(duì)稱，平衡，非平衡和對(duì)稱的部件是什么意思
Abstract New terminology is introduced to make clear the relationship between harmonics and symmetrical components. Three-phase sets are classified in terms of symmetrical sets and asymmetrical sets. Subclasses are introduced with the names symmetrical balanced sets, symmetrical unbalanced sets, asymmetrical balanced sets and asymmetrical unbalanced sets to show that a threephase set can resolve to either one, two or three symmetrical component sets. The results from four case studies show that these subclasses and their resolution to symmetrical component sets improve understanding of harmonic analysis of systems having balanced and unbalanced harmonic sources and loads.
Keywords asymmetrical sets; harmonic flows; harmonic sources; symmetrical component sets; symmetrical sets
Any periodic wave shape can be broken down into or analysed as a fundamental
wave and a series of harmonics.
