电力设备在运行中受到电、磁、热、力及流体等多物理场的综合作用,多物理场耦合仿真对保证电力设备设计最优性以及运行可靠性不可或缺。在电力设备多物理场计算及软件开发时须攻克材料非线性建模、快速瞬变多空间/时间尺度问题等效方法、多场耦合作用机理及数学模型的建立、大规模微分代数方程组(DAE)的稳定高效求解等关键问题。为此,分别从材料参数等效、多场耦合计算技术、大规模跨尺度计算、DAE方程组求解等方面介绍了自主软件开发过程中应该重点关注的研究内容和算法技术。为促进基于数值仿真的数字孪生技术在电力设备领域的应用,总结分析了集成几何/仿真分析于一体的等几何分析法、模型降阶方法和基于数据驱动的多物理场仿真方法等新型技术。最后,针对国产计算机辅助工程(CAE)软件存在的问题,分析了国内外多物理场软件开发技术发展现状,并对研发国产电力设备多物理场计算软件作了展望。
Power equipment is subject to the combined effects of multiphysics fields such as electricity
magnetism
heat
force
and fluid during the operation. Multiphysics coupling simulation is indispensable to ensure the optimal design and operation reliability of power equipment. In the multiphysics field calculation and software development for power equipment
it is necessary to overcome the key issues such as the modeling of material nonlinearity
fast transient methods with multiple space and time scales
multi-field coupling mechanism and the establishment of mathematical models
and stable and efficient solving of large-scale and differential algebraic equations (DAE). Therefore
the research subjects and algorithms that should be focused on in the process of independent software development are introduced from the aspects of material parameter equivalence
multi-field coupling calculation technology
large-scale cross-scale calculation
and DAE solution. To promote the application of digital twin technologies based on numerical simulation in the field of power equipment
new technologies such as the isogeometric analysis method integrating geometric/simulation analysis
reduced-order model method
and data-driven multiphysics simulation method are summarized and analyzed. Finally
because of the problems in the indigenous computer-aided engineering (CAE) software
the development status of the indigenous and overseas multiphysics software development technologies is analyzed
and the development of multiphysics calculation software for indigenous power equipment has been prospected.
