摘　　要：铁芯电抗器振动的主要原因包括铁芯的麦克斯韦力及硅钢片的磁致伸缩效应。为了准确地建立硅钢片磁致伸缩模型,基于Jiles-Atherton磁滞模型,并根据软磁材料的二次畴转模型理论,建立铁磁材料磁致伸缩模型,采用自适应模拟退火(adaptive simulated annealing,ASA)算法提取模型中的多个参数。在确定磁致伸缩模型有效性的基础上,利用多物理场仿真软件构建考虑磁致伸缩模型的干式铁芯电抗器振动计算模型,分析铁芯电抗器铁芯的振动分布特点,结合拉丁超立方抽样实验方法与Kriging模型建立能够准确预测铁芯振动位移的优化模型,在均衡铁芯电抗器电磁及振动特性的情况下使得铁芯上的金属导体用量最小化,获得电抗器铁芯的最佳结构。并对比分析优化前后电抗器模型的特性,优化数据显示,电抗器铁芯部分的金属导体用量相较于优化前降低9.21%,且此时的电感仅改变了0.31%,同时优化后铁芯振动减少18.18%,满足电抗器电磁及振动要求。The main reasons for the vibration of iron core reactor include the Maxwell force of the iron core and the magnetostrictive effect of the silicon steel sheet.To accurately establish the magnetostrictive model of silicon steel sheet,the magnetostrictive model is established based on the secondary domain transition model of soft magnetic materials combined with the Jiles-Atherton hysteresis model,and adaptive simulated annealing(ASA)algorithm was used to extract multiple parameters in the model.Based on confirming the validity of the magnetostrictive model,the multi-physics simulation software is used to construct the vibration calculation model of the dry-type iron-core reactor considering the magnetostrictive model.The vibration distribution characteristics of the iron core are analyzed,and an optimization model that can accurately predict the vibration displacement of the iron core is established by combining the Latin hypercube sampling and the Kriging model.In the case of balancing the electromagnetic and vibration characteristics of the core reactor,the amount of metal conductors on the core is minimized,and the optimal structure of the core of the reactor is obtained.The characteristics of the reactor model before and after optimization are compared and analyzed.The results show that,after optimization,the amount of metal conductors in the core of the reactor is reduced by 9.21%;the inductance error is only 0.31%;the vibration of the core is reduced by 18.18%,which meets the electromagnetic and vibration requirements of the reactor.
