  以部分最优解为中间机关相信域并计较其相信度,只对那些有代价的相信域停止部分搜刮,疾速求出全局最优解,使得该算法加倍间接、靠得住,计较效力获得进步仍以35k V、5 000k VA双绕组无励磁调压电力变压器为例,按上节实际体例变压器优化法式,第一阶段,假设死心直径规模以340mm为中间(这里以D=340mm为例), 磁通密度取值1.7T~1.65T,按式(7)计较绕组匝数取值规模330匝~340匝,以空载消耗为方针值,可计较出绕组高度H0(临 界点 )和绕组辐向尺寸C,和对应死心窗高下限HW和中间距下限M对临界点。

  按变压器的三变量算法实际停止计较,在给定的绕组空间上,按最好排线法则对绕组排线,肯定绕组线规(a×b),并计较变压器负载消耗和高、高压绕组温升,并对高、高压绕组辐向尺寸停止批改,这里高压按1.05,高压按0.95批改。 D=340mm时的临界点负载消耗和高、高压绕组温升计较成果参考变压器空载消耗、负载消耗和高、高压绕组温升,自界说这些方针的最大许可值,可判定死心直径D=340m和绕组匝数W所对应的取值空间是不是存在解空间。
