确定架空线路控制气象条件的多目标优化法

Multi-objective Optimization for Climate Condition Control of Overhead Lines

架空线路应力控制气象条件的判定,需要考虑控制气象条件及弧垂限制等条件,一般采用临界档距判定法或试推比较法处理.本文建立了解决该问题的多目标优化数学模型,并采用罚函数法求解模型,算例证明了相对于传统方法的优越性.

In order to judge the climate condition control of overhead - line stress, it is of necessity to take account of climate condition control and hang-arc-distance restraint. The common way in which this problem was coped tended to be dividing-distance judgment or try-deducing comparison. And this paper proposes a teaching model of multi-objective optimization with the use of penalty function method. The examples testified the superiority to traditional methods. The presented algorithm is of great significance both in theory, and in engineering practice.
