摘 要:针对重过载线路导致输电线路损耗增大的问题,建立输电线路改造节电量计算模型,并给出了该模型中增加一条并列运行线路、增加一条不等截面导线、增大导线截面以及线路升压四种方案的节电量计算方法。以某供电局为例,进行输电线路改造的节电量计算和分析,结果表明采用不同的模型进行重过载线路改造会产生不同的节电潜力,在实际的改造过程中应根据经济、可行性等因素考虑使用多种方案。

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
