基于适当正交分解的模型简化技术被应用于电准静态场方程的有限元公式。所提出的公式考虑了介电效应以及非线性导电效应。该实现基于二维轴对称模型。所应用的固有正交分解基于奇异值分解。显示了由恒定和非线性导电材料组成的轴对称高压避雷器的数值结果。
A model reduction technique based on the proper orthogonal decomposition is applied to a finite-element formulation of the electroquasistatic field equation. The presented formulation takes into account dielectric effects as well as nonlinear conductive effects. The implementation is based on a 2-D axial symmetric model. The applied proper orthogonal decomposition is based on the singular value decomposition. Numerical results are shown for an axial-symmetric high-voltage surge arrester consisting of constant and nonlinear conductive material.
