摘　　要：研讨了工厂和矿山的输电线路、均匀网络的最佳功率分配和最佳电流分配以及导线截面与电流的关系,给出 I=f(A)曲线。分析了导线电流 I 与导线电阻 r 的关系,得出I=f(r)的曲线.通过对最佳截面的选取进行计算和无功功率对输电系统的影响进行分析,得出了最佳运行的补偿方法,并且探讨了不同并联线路的最佳运行问题。In this paper, it is mainly discussed that the optimal allocations of the power and current of the transmission lines and uniformity networks in factories and mines, as well as the relationship between the wire section and current. On the basis of these, the curve of I=f （A）. is obtained. The relationship between the wire current I and the wire resistance r is analyzed and the curve of I= f（r）. is derived. Through calculating and selecting the optimal section and analyzing the influence of reactive power on the transmission system, a compensation approach of the optimal operation is obtained. The optimal operation subject of different parallel lines is also discussed.
