中文摘要 | 本文提出系統性負載特性調查程式來研究溫度變化對電力系統負載需量的影響。藉由各類型用戶典型日負載模型,配合各類型用戶售電資料,推導臺電系區處日負載模型。為驗證推估負載組成的準確性,模擬的結果將與SCADA系統所收集到的實際負載量來進行比較。根據用戶用際耗電量與溫度資料,進行統計學迴歸分析,亦即每一用戶相對於溫度變化之負載需量被感性皆析。當溫度變化時,藉由各類型用戶之溫度敏感性,更新各類型用戶對區處負載貢載度,同時形成區處新的負載模型。為調查溫度對配電系統運轉的影響,選擇一修臺電配電饋線來進行電腦模擬。應用溫度敏感度計算每一配電饋線窅載匯流排的負載需量,同時執行三相負載潮流分析,獲得溫度變化應新的饋線負載量及饋線實功損失。 |
英文摘要 | A systematic procedure is proposed to study the effect of temperature change to the power system load demand by using the typical load patter customer classes. The billing data of all service customers are retrieved to derive the daily load profile of the selected Taipower district. To verify the accuracy of the estimated load composition, the simulation results are compared to the actual load profile collected by the SCADA system. The sensitivity analysis of lad demand with respect to the temperature change for each customer class is performed by statistic regression according to the actual customer power consumption and temperature data. The load contribution by each customer class is updated by the corresponding temperature sensitivity and integrated together to form the new lad profile of a service district with temperature change. To investigate the temperature effect to the distribution system operation, one of the Taipower distribution feeders is selected for computer simulation. The power demand at each load bus of the distribution feeder is calculated by applying the temperature sensitivity and the three-phase lad flow analysis is then executed to find the new feeder loading and power loss with the temperature change. |
