Research on Simulation Calculation method and Energy-conserving analysis of Energy-Saving Conductors

摘要

Line losses are needed to be calculated before overhead transmission lines put into operation, and meanwhile AC resistance of wires determines its resistive losses and transmission capacity. In this paper, we compared several commonly used methods of AC resistance, obtain their advantages and disadvantages, and optimized choose the resistance calculation parameters. Finally, calculates the resistive losses of high conductivity steel core hard-drawn aluminum wire, aluminum alloy core aluminum wire and mid-strength aluminum alloy stranded wire in order to verify the accuracy of the algorithm, and provides a powerful data reference for the selection and design of wires in the future.
