特高压线路棒形悬式复合绝缘子表面电位分布极不均匀,绝缘子高压端金具附近绝缘子护套表面局部电场强度很大,加速了绝缘子的老化。工程上通常用安装均压环的方法来解决该问题。均压环结构参数决定了其均压效果,为得到较优的均压环参数,需要对其管径、环径、罩入深度的优化设计进行研究。由于复合绝缘子的结构特点使得单元数量较多,求解耗时长,常规遗传算法应用于该课题具有优化过程耗时较长的问题,因此使用改进的优化算法对均压环参数进行优化。改进的RBF-GA混合算法综合了RBF神经网络任意函数逼近能力和GA算法的全局优化能力 ...

盆式绝缘子是高压气体绝缘设备重要的绝缘部件,其性能优劣直接影响高压设备的稳定运行。针对盆式绝缘子,以提升整体电场分布均匀性为优化目标,基于有限元迭代计算的方法,提出盆式绝缘子电场综合优化方案,通过优化算法改变盆体结构和梯度材料介电常数,得到绝缘子最优电场分布。仿真结果表明,对比匀质盆式绝缘子,在满足机械性能情况下,综合优化后体/表层梯度盆式绝缘子凹凸面最大场强降幅分别为35.79%、30.59%和29.28%、29.51%,优化效果显著。
