摘要
本文在理论分析的基础上,提出了交替修正优化电荷的电量和位置参数与FLETCHER—优化模拟电荷法相结合的电极优化新方法。实际算例表明,该方法的收敛性能明显优于单纯修正电荷位置的电极优化法,降低了对电极初始形状和模拟电荷初始参量的要求,并且还避免了单纯修正电量方法困电荷位置固定而可能产生的优化失败问题。应用本文方法对GIS内部的母线端子进行优化设计,获得了令人满意的结果。
Based on the theoretical analysis, a new approach for optimising electrode contour is described, which combines the correction of coordinates and magnitudes of optimization charges with Fletcher-Optimized Charge Simulation Methed. Practical calculation indicates that the convergence of the new approach is obviously superior to that of the other algorithm which only corrects the locations of optimization charges. It also denotes that the optimization results obtained by the described approach are more ideal in comparison with another algorithm which merely uses the values of optimites charges as optimization variables. The difficuties caused by fixing the locations of fictitious charges have been overcome. The restrictions on choosing the initial contours of electrodes and the initial parameters of simulation charges are reduced.By means of the edscribed approach on optimization calculation has been made on metal-clad bus terminal in GTS. The result is found to be very satisfactory.
