| 摘 要： | 针对一般方法及CDEGS在计算接地系统暂态性能时均未考虑土壤电离的非线性特性影响的问题，提出了将CDEGS和自编程序相结合并考虑土壤电离因素对地网冲击特性进行分析的新方法，以不同地网结构为例，比较了该方法与其他考虑土壤电离的频域方法的计算结果。结果表明，本文方法合理、有效、简便、快捷。

| Abstract: | The general method and CDEGS compute the impulse characteristics of grounding system without considering nonlinear influence of soil ionization. The combination of CDEGS with programming is proposed to compute the impulse characteristics of grounding grid by considering soil ionization factor. Taking different structure of grounding grid for an example, the proposed method is compared with other methods in frequency domain which consider the factor of soil ionization. The results show that the proposed method is reasonable, effective, simple and quick. |
