    摘 要:針對重過載線路導致輸電線路損耗增大的問題,建立輸電線路改造節電量計算模型,并給出了該模型中增加一條并列運行線路、增加一條不等截面導線、增大導線截面以及線路升壓四種方案的節電量計算方法。以某供電局為例,進行輸電線路改造的節電量計算和分析,結果表明采用不同的模型進行重過載線路改造會產生不同的節電潛力,在實際的改造過程中應根據經濟、可行性等因素考慮使用多種方案。
    關鍵詞:輸電線路改造;節電;重過載線路

    Abstract: Aiming at the problem that heavy-loaded and overloaded circuits increased the loss in transmission lines, this paper established the reconstructed calculation models for the transmission lines and gave four kinds of electricity-saving calculation plans, including adding a parallel operation line in the model, adding a different constant section line in the model, increasing conductor cross section and uprating transmission line voltage. With certain power supply bureau as an example, this paper carried out electricity-saving calculation and analysis of transmission lines. The result shows that taking different models to reconstruct heavy-loaded and overloaded transmission lines will operate different electricity-saving potentials. In actual improvement process, different kinds of methods should be used in consideration of economy and feasibility etc factors.
    Key words: transmission line reconstruct; electricity-saving; heavy-loaded and overloaded circuit
