一种改进型电力线路导线截面选择的设计方法

针对目前按照经济电流密度法选择的导线截面偏大的问题,设计了一种新的截面优化选择方法来减小偏大值以得到相对较合理的截面。实例计算结果验证了该方法的正确性和有效性,从而为导线截面的设计提供了新途径。

An Improved Design Method of the Conductor Section Selection of Power lines

In view of a little large conductor section of economical current density selection,a new kind of optimal secticn selection is designed to reduce higher value to get rational section.The calculating result of the example has proved validity and availability of the method.Thus a new way of the conductor section design is given.
