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(jié)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(jié)電量計算方法。以某供電局為例,進行輸電線路改造的節(jié)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(chǎn)生不同的節(jié)電潛力,在實際的改造過程中應根據(jù)經(jīng)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(jié)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
