大型地网接地电阻数值计算的初步研究

Numerical calculation of earth resistance on large scale grounding grids

从电磁场理论出发，应用矩量法求出大型地网的电荷分布和电容，从而导出接地电阻计算的一种新方法，并编制出计算机程序，算例结果证明了本方法的有效性。

According to the electromagnetic theory, a new method of the numerical calculation of resistance of the ground grids is developed. This method is deduced from the distribution of the charge and the electrical capacity figured out with the principle of the moment method. A practical example is given to prove its validity.
