为找到一种使输电线分布参数求解的平均误差最小的优化算法,通过试验手段获取了不同频率下不同点的电压值,利用终端开路的方法求解了传输线方程,计算出不同优化算法下的衰减常数和相移常数,并对各优化算法进行了验证,求出了各算法之间的相对误差。结果表明,工程试验可有效地提高选择优化算法的效率,从而利用该算法对传输线做进一步的理论(求解)分析。
In order to find an optimization algorithm that minimizes the average error of distribution parameters of power transmission line, voltage values of different points under different frequencies are obtained by experiment. The equations of transmission line are solved by terminal open circuit and the attenuation under different optimization algorithms is calculated Constants and phase shift constants, and verify the optimization algorithms to find the relative error between the various algorithms. The results show that the engineering experiment can effectively improve the efficiency of the selection optimization algorithm, and then use the algorithm to further theoretical analysis of the transmission line.
