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 optimization algorithm in calculating the distribution parameters of the transmission line which would feedback the smallest error, various points of voltage value in different frequency were obtained with experi- mental mean. The attenuation constant and phase constant were solved via different algorithms under the conditions of open circuit. And the different optimization algorithms are verified. Then it calculates the relative error of different algo- rithms. The results show that engineering test can effectively improve the efficiency of selection of optimization algorithm and take advantage of the selected algorithm for further theoretical analysis of transmission lines.
