    Abstract: 本研究藉由配電線路損失分析簡化模型,以達到提升損失分析之效能,並利用配電系統自動圖資及設備管理系統資料庫中完整之配電設備資料,透過拓樸分析及節點減量技巧,建立簡化之配電線路模型架構。其中本研究以負載特性為基礎,根據抽樣用戶之用電資料庫,整理住宅、商業及工業類型用戶用電資料,以統計分析推導各類型用戶標準化日負載模式,同時配合用戶服務資訊系統之用戶售電資料,依據標準化日負載模型,並利用系統資料庫所提供之線路變壓器與用戶電號的對應關係,推估線路變壓器每小時負載量。將簡易之線路模型結合線路相關資料,利用電力負載潮流程式,計算線路損失,以建立相關資料,裨便掌握配電線路出口供電量、線路長度、變壓器容量、線路供電電壓與線路損失之對應關係,估算不同類型線路之損失。根據上述計算結果分析得知,都會區之線路損失由於線路較短,但用戶數眾多,且線路變壓器負載較重,故變壓器損失及低壓線路損失較高;而在郊區之饋線則大多為長距離之架空線,供給用戶分散較廣,其線路損失亦會較高。因此對於台灣電力公司而言,若能透過配電饋線損失分析模式,則將能迅速估算配電饋線之損失,以提供各區處改善配電系統運轉效率之參考。This paper is proposed to study the distribution system loss through a formulation of simplified modeling. To enhance the efficiency of loss analysis, the distribution system operation data can be effectively obtained by retrieving component information from database system of Taipower distribution system, while the topological analysis as well as the node reduction is also applied to identify the network configuration. In the project, the load survey study is used to derive the typical load patterns of various customer losses. The monthly energy consumption of customers by each transformer, which has been retrieved from the database system, can be used to derive the hourly loading of each distribution transformer. The power load flow program can be applied for different types of distribution feeders to solve feeder loss. In this way, the distribution loss analysis can be more effectively solved based on the feeder load demand, length, transformer capacity and voltage level. With short feeder length and voluminous customers served by the distribution feeders in urban area, the transformer loss and secondary line loss contribute most of distribution feeder loss. On the other hand, the line loss of rural distribution feeder is more significant because of longer distribution lines serving more scattering customers. With the distribution system loss modeling, the distribution system loss can be estimated easily, hence serving as a useful reference to enhance the operation efficiency of distribution systems.
