【摘要】：电磁脉冲会在多导体传输线中感应出较高幅值的感应电压和电流,对传输线端接设备等具有严重威胁。所以,对多导体传输线进行建模,分析多导体传输线电磁脉冲响应对于预测电力线的电磁脉冲效应,研究其保护方法具有重要的意义。在多导体传输线建模方面,传统的链参数矩阵算法由于存在大量的矩阵求逆运算,在存在大量线缆时其计算速度较慢。基于此问题,提出了基于解析迭代方法的多导体传输线电磁脉冲响应计算方法(DARIT-field),该方法在求解每根线缆上的响应时,将临近线缆的串扰耦合效应等效为在临近线缆上均匀分布的激励源,计算过程得到了大幅简化。并对基于不同迭代方法的多导体传输线电磁脉冲响应计算方法进行了对比,最后利用实例对每种方法的优、缺点进行了对比。
[Abstract]:Electromagnetic pulse induction induction voltage and current with high amplitude in multi conductor transmission line, the transmission line terminal has a serious threat. Therefore, modeling of the multi conductor transmission line, analysis of multi conductor transmission line electromagnetic pulse response of electromagnetic pulse to predict power line flush effect, it is of great significance to study the protection method. Modeling in multi conductor transmission line, the traditional chain parameter inverse matrix algorithm due to the presence of a large number of matrix, in the presence of a cable when the slow computation speed. Based on this problem, put forward the multi conductor transmission line analytical iterative method for electromagnetic pulse response calculation method based on (DARIT-field), the response of this method in for each cable when the equivalent cable crosstalk coupling effect will be near uniform distribution near the cable on the excitation source, the calculation process is greatly simplified. And based on the Compared with the iterative method, the calculation method of electromagnetic impulse response of multi conductor transmission line is compared. Finally, the advantages and disadvantages of each method are compared with the examples.
