radial sweep 中文意思是什麼
radial sweep
解釋
徑向掃描-
Though adopting the - coordinate transformation in the control equations and mode - splitting technique, the external mode ( surface gravity waves ) is solved by the improved double - sweep - implicit finite difference method ; the internal mode ( internal gravity waves ) untilizes the eulerian - lagrangian method, which improves the implicit - difference scheme for the vertical direction. the newly developed 3d numerical tidal model with implicit scheme has been successfully applied in the radial sandbanks area
基於過程分裂法及垂向坐標伸縮變換，外模式採用改進型雙步全隱有限差分dsi法，內模式採用歐拉?拉格朗日公式，改進了三維垂向隱式格式，成功地建立了南黃海輻射狀沙脊群海域三維全隱格式潮流數學模型。 -

摘要前推回推法是放射形配網潮流計算最基本的演算法。 -
Tests on a practical radial distribution system have shown that, the proposed method is as robust as, but more efficient than the back / forward sweep method
文中以一個實際的中等規模配電系統為例，分析、比較前推回推法、導出的近似牛頓法、經典牛頓法等的收斂性和計算速度，證實上述研究結論。 -
The content including : ( 1 ) according to the radial structure and multilayer characteristic of distribution network, a novel layer - by - layer backward / forward sweep method id developed. the branch power / voltage loss of the same layer can be parallel computed without relabeling buses and branches, that greatly increases the speed of load flow calculation
其主要內容如下： （ 1 ）針對配電網路的樹狀結構和層次特性，研究了一種新穎的分層前推回代潮流演算法，該演算法不需要網路節點和支路的特殊編號，可以并行計算同一層次所有支路的功率損耗和電壓損耗，從而大幅度提高了潮流的計算速度。
