中文摘要 | 本論文之目的旨在發展一套電腦模擬程式,於含有諧波污染的三相不平衡配電系 統中,研究並聯補償器裝置位置及容量之最佳歸劃。論文首先將虛功補償執行非線性歸劃, 在維持系統電壓失真因數(HDF)於合理的操作範圍條件下,決定並聯補償器之虛功補償量之 裝置模式,使系統中饋線各級頻率下之電力和電能損失以及電容器投資成本所組合而成的目 標函數值最低。然後利用三相諧波分析程式計算電容器補償後系統之諧波失真因數,並據以 計算應裝置濾波器之最佳位置與其組成元件,如電抗器及電容器之額定容量及額定電壓。 論文中將考慮多重諧波源、三相不平衡及線間耦合效應,以增進模擬之準確性,此外電 容器容量將考慮成實際之固定化規格。最後將以一條實際的工業饋線進行分析模擬,以驗證 所提研究方法之效率與準確性。 |
英文摘要 | The objective of this project is to decide the optimal location and size of shunt capacitors and filters for the three-phase unbalance distribution systems with harmonic distortion. In this project, the problem of reactive power compensation is first formulated as a nonlinear programming of minimization of real power loss, energy loss and capacitor cost under harmonic voltage constraint to decide the optimal locations and sizes of shunt capacitors. The three-phase harmonic load flow program is then applied to solve the total voltage harmonic distortion factor (THD) of capacitors compensated system to decide the locations of filters. Finally, the tuning frequency of the single- tuned filter and the capacity and voltage ratio of the corresponding reactor and capacitor are determined so that both the harmonic distortion and the reactive power compensation can be solved simultaneously. To demonstrate the performance and effectiveness of the proposed methodology, a practical distribution feeder with several large industrial customer will be selected for computer simulation. |
