Test Analysis of Distribution Parameters of Tansmission Line Via Optimization Algorithm

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 experimental 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 algorithms. 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.
