| 中文摘要 | 本文提出實際的電容器規劃策略來降低配電系統電阻損並且改善配電饋線電壓剖面。首先,藉由非線性規劃技巧來推導最佳電容器的大小和並聯電容器的安裝位置當作計算參考。其中目標函數是由尖峰負載損、能量損和電容器成本所組成;而運轉限制殊如匯流排電壓剖面和離散的電容器大小。三相負載潮流程式中考慮導體間互耦合效應、相間的不平衡負載、具有主饋線和分歧線的配電系統結構,來增強電腦模擬的準確性。根據饋線的典型日負載曲線,發展出固定式及切換式等兩種實際的電容器規劃,來決定電容器適當的大小、位置和切換時間等,達到更有效地虛功控制以降低電阻損。為了驗證本文方法的有效性,選擇一條實際的臺電饋線來作電腦模擬。求得實功損和電壓剖面以及饋線的運轉效率,估算出本文電容器規劃策略的成本效益。本文所提方法和臺電現行採用的虛功補償策略,相比之下,証明本方法對於配電工程師在完成虛功控制和規劃時,是有效率且是實際的工具。 |
| 英文摘要 | A practical capacitor planning strategy to reduce system resistive losses and improve voltage profile for distribution feeders has been proposed in this paper. At first, the capacitor design method by applying nonlinear programming technique is formulated to derive the optimum size and installation location of shunt capacitor banks as the evaluation reference. The objective function is consisted of peak load loss, energy loss, and capacitor cost, while the operation constraints such as bus voltage profile and discrete capacitor size are considered throughout overall solution procedure. A three-phase load flow program, which includes the mutual coupling effect between conductors, unbalance loading among phases, and the feeder with configuration of laterals, is applied to enhance the accuracy of computer simulation. According to the typical daily load duration curve of the study feeder, the practical capacitor planning by considering both fixed and switched type capacitors are developed to dectermine the proper size, location, and switched time of capacitors so that the resistive loss introduced by the reactive power flow can be effectively reduced. To Demonstrate the effectiveness of the proposed method. one practical feeder in Taipower distribution system is sclected for computer simulation. The real power loss and the voltage profilc are solved and the operation efficiency of the study feeder is determined to estimate the cost benefit of the proposed capacitor planning strategy. As compared with the present strategy adopted by Taipower for reactive power compensation, it is found that the proposed method does provide more efficient and practical tool for distribution engineers to achieve better reactive power control and planning. |
