Powerformer have some changes in constract with the conventional generator ， subsequently it also have some new problems in order to have an economical ， efficient ， credible development and application the structure and the philosophy of electromagnetism of powerformer will be on speaking terms changes electrical design ， magnetism design ， thermal design and structural design are have some new changes above all ， the electromagnetism parameter and the harmonic magnetomotive force of powerformer are studied in this paper first ， it mainly utilizes analytics to deduce formula of slot leakage reactance it considers three instances ， including monolayer - slot ， multilayer isometric - slot and multilayer anisometric - slot then ， the analytics and the fem are utilized to calculate slot leakage reactance of stator winding of prototype of powerformer and compare their results second ， the theory of utilitzing fem to calculate the reactance of powerformer is simply introduced ， including stable reactance ， transient and subtransient reactance specially ， the saturated influence of the stable reactance is considered then ， the results are analysed final ， it mainly introduces the influence of harmonic magnetomotive force of stator winding and analyses the harmonic magnetomotive force of stator winding then ， it mainly analyse harmonic magneto - motive force of stator winding through arranging various arrays of stator winding and observe their influence
基於上述原因，本文對powerformer的電磁參數以及定子繞組諧波磁勢進行了研究。首先是用解析法推導出powerformer定子繞組槽漏抗的計算公式，考慮了單層圓形半閉口槽、
多層等半徑圓形半閉口槽和
多層不等半徑圓形半閉口槽三種情況，並對powerformer樣機的定子繞組槽漏抗用解析法和有限元法進行了計算，並比較其結果；其次，
簡要介紹了有限元法計算powerformer電抗參數的原理，包括穩態電抗、瞬態電抗和超瞬態電抗，對穩態電抗考慮飽和影響，對結果進行分析；最後，介紹定子繞組諧波磁勢對電機運行性能的影響並對定子繞組諧波磁勢進行了分析。然後通過對定子繞組進行不同排列來分析定子繞組諧波磁勢，看看繞組排列對諧波磁勢的影響。

Arcuated built - up system bridges are one of bridge structural styles, which are used extensively at present. on one hand, because of complexity and diversity of this kind of structure, current engineering experiences have not satisfied design requirements no longer. on the other hand, towards this kind of structural system traditional methods simplify complicated structures into planar structures, these methods neglect apparently spatial action among members, especially those primary bearing load members along lateral direction of bridges
拱式組合體系橋梁是目前廣泛採用的一種橋梁結構形式，一方面由於拱式組合體系橋梁結構的復雜性和
多樣性，現有的工程經驗已不能滿足設計需求；另一方面對于這種結構體系過去的傳統做法是將復雜結構
簡化成平面結構，這種做法顯然忽略了構件之間的空間作用，尤其是沿橋橫向存在主要承力構件。
