中文摘要
本論文針對台電系統之停限電運轉圖資管理系統(Outage Management Systems, OMS),利用相別量測器(Phase Measurement Unit, PMU),進行配電變壓器相別之量測,以確認現場設備正確之相別。此外亦發展多點對多點之電力線載波(Power Line Carrier, PLC)關聯性檢測器,以辨識配電變壓器所供電之用戶,可提供未來各區處完成配電變壓器與受電用戶連結關係之確認,有效提高配電系統OMS之資料準確性,如此將可提升低壓事故之搶修效率,並支援配電變壓器之負載管理。
論文中選擇鳳山區處四條饋線,擷取配電系統OMS資料庫所登錄之饋線區段導線相別和變壓器相別。再進行導線及變壓器相別全面量測及核對,為支援配電系統之三相負載潮流分析,本論文亦開發人機介面以自動擷取饋線相關資料,透過網路拓樸分析及節點減量,建立簡化之配電饋線網路架構。根據用戶資訊系統(Customer Information System, CIS)之用戶售電資料,配合不同類型之用戶典型日負載模型與變壓器及用戶之連結關係,推導變壓器每小時之負載量。最後考慮配合配電調度中心(Distribution Dispatch Control Center, DDCC)所收集之饋線出口每小時實際供電量,修正變壓器每小時負載量以作為三相負載潮流分析匯流排之負載資料。將簡化之饋線網路模型結合所有匯流排之負載值,執行三相負載潮流分析程式並應用於配電饋線三相不平衡電流分析之研究上。
Abstract
The objective of this thesis is to update the outage management system (OMS) in Taipower by verifying the phasing of distribution transformers and the connectivity of customers served by each distribution transformer. The GPS based phase measurement unit (PMU) is used to measure the voltage phasing of the transformer. The power line carrier (PLC) based identifier has been developed to support the identification of distribution transformer and all the customers served.
In the thesis, four practical distribution feeders in Fengshan District of Taipower are selected for the update of distribution transformer phasing of OMS system for the update of distribution transformer phasing of OMS system. After correcting the phasing of distribution transformer in the OMS database, the attributes of distribution components are retrieved for the OMS system. The network configuration of distribution feeders is identified by exacting the topology process and node reduction to prepare the input data for load flow analysis. With the monthly energy consumption of customer from the customer information system (CIS) and the typical load patterns of various customer classes, the hourly loading of each transformer can be derived. By retrieving the actual power data of test feeders from the distribution dispatch control center (DDCC), the three phase load flow analysis is executed to solve the three phase currents of trunk line sections, laterals and distribution transformers. The three phase currents solved can therefore be applied to derive the strategy of three phase balancing of distribution feeders.
