紧凑型线路导线排列的多目标优化

MULTI-OBJECTIVE OPTIMIZATION FOR THE CONDUCTORCONFIGURATION OF COMPACT LINES

导线排列的优化是紧凑型线路设计的关键问题之一。本文介绍多目标优化技术，结合我国工程实际，对分裂导线布置的形状与分裂距离加以约束。文中对２２０ｋＶ安定一廊坊及５００ｋＶ紧凑线路导线的优化排列作计算并与常规线路比较，对不同排列方案的电气参数及电磁环境影响作了评估。

Compact tine can increase the surgei,npedance loading and transmission capacity densityand can reduce the corridor width siknificantly. Theconductor configuration optimization is one of the keyproblems in the compact line design. In the paper, themulti-objective optimization technique is introduced andthe shape and the spacing of the bundles are used asconstraints conforming with engineering proctice inChina. The optimized conductor configurations of the220 kV An-Lang compact line and 500 kV compact lineare compared with conventional lines. The electricatparameters and environmenial effect values of differentconfiguration schemes are assessed
