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
