应用离散规划算法的电力变压器优化设计

A Nonlinear Discrete Programming Algorithm for the Optimum Design of Power Transformers

本文应用非线性离散规划算法求解三相电力变压器电磁参数的优化设计。所得的设计参数可以在实际中直接使用。文中以主要有效材料费最小为优化目标、以规定的变压器性能指标、材料性能及工艺要求和设计变量的上、下限等作为约束,建立优化数学模型。应用离散规划算法所得的计算结果与连续规划经过园整的结果进行了比较。

A nonlinear discrete programming algorithm is adopted to optimize electro-magnetic parameters of three-phase power transformers in the sense of minimizing costs of main materials subject to performance requirements constraints and upper or lower limits on design variables. The transformer design results by using the discrete programming are compared, to those obtained by the continuous programming and rounding-off technique. The optimum discrete solutions can be used directly in engineering practice without rounding-off processing.
