摘要:
介绍了一种采用遗传算法来设计中压室内支柱绝缘子的优化方法,所设计的绝缘子形状不仅改善了绝缘子内部和空气中的电场分布。还优化了绝缘子外部形状,以及基于多项式的算法优化,同时还创新的使用了分压器。该绝缘子使用了陶瓷电容,比使用圆支柱金属网的常规绝缘子更容易达到所需要的电容数值。利用MATLAB软件建立了绝缘子模型; 并用EleFAnT软件计算电场分布; 采用微分进化算法得到了绝缘子外部形状和内部元件位置的最优解。结果表明优化后的新绝缘子对于经济性和电气性提高较为有效。
Abstract:
An innovative method of post insulator design based on genetic algorithm is introduced. The new insulator shape improves the electric field distribution inside the insulator and in the air. The concrete content of promotion is on the one hand the innovative design of external shape and the enhancement of polynomial, and on the other hand the use of voltage divider. The insulator uses ceramic capacitance, diversely from previous insulators, which cannot reach the required capacitance due to the use of cylindrical metal mesh. In this paper, MATLAB software is used to establish the insulator model; EleFAnT software was used to calculate the electric field distribution. The optimal solution of insulator external shape and internal element position is obtained by differential evolution algorithm. The results show that this optimal design improves the economic and electrical performance of insulator.
