针对消磁站沿地磁东西方向建设时地磁场的补偿问题,研究了横向地磁补偿线圈的布置方案及优化问题,提出了补偿线圈部分交叠放置的布置方法,并采用Powell法对补偿线圈中的补偿电流进行了优化。实验结果表明:线圈交叠放置确实能改善横向地磁的补偿情况,而如果将交叠线圈中的电流作为独立变量分别进行优化时,横向地磁的补偿效果将得到明显的改善。
To solve the problem of compensating for the geomagnetic field around a degaussing station which lies in the east-west geomagnetic direction, this paper makes a study of the layout and optimiza- tion of transverse compensation coil and proposes a method of laying out partially-overlapping compen- sation coils. And Powell is used to optimize the current in the compensation coil. Experimental results show that partially-overlapping compensation coils can improve the compensation for transverse geo- magnetism and that the compensative effect of geomagnetism will be greatly increased if the current in each compensation coil is optimized when it serves as an independent variable.
