摘要

電業自由化的環境下，輸電系統的使用費用，將由使用者公平合理的分攤。本論文以負載潮流分析結果和電路學的理論為基礎，推導出系統中使用者在各線路的電流分解量，以獲得各線路的損失分解量。並依據各使用者在線路上造成的損失多寡計算出各使用者在該線路的使用率，以決定分攤線路使用費之比例。這種方法可以克服以往採用電力流量或電流量計算線路使用率時，因其非線性之關係導致成本分攤的失真。

Under the deregulation environment of power industry, the costs of transmission service should be fairly allocated to users. Based on the power flow results and circuit theory, this thesis is to calculate the contribution of line loss by decomposing line current which is related to the corresponding users in order to determine the ratio of transmission utilization. The proposed strategy that is different from the existed methods adopts the decomposed transmission line loss to avoid the non-linear relation of power flow or current which causes cost allocation distortion.
