摘    要:针对接地网受雷击时地电位分布不均的问题,提出了基于果蝇算法的接地网优化设计方法。首先根据接地体的通用数学模型搭建EMTP接地体单元模型,并在此基础上搭建小型接地网模型,仿真计算其雷电暂态效应。然后再以优化地网电压为目标,通过果蝇算法来寻找地网最优压缩比。仿真表明,采用本方法可有效提高地网运行的安全水平。

关 键 词:接地网  优化设计  雷电暂态效应  果蝇算法  电磁暂态仿真

Abstract:In order to deal with the uneven electric potential distribution of grounding grid surface by lightning,an optimal design method for grounding grids was proposed based on the fruit fly algorithm.According to the general mathematical model of grounding conductor structures,EMTP grounding conductor model was set up and used to simulate and calculate the lightning transient effect of a grounding grid.Then the voltage of the grounding grid was optimized and the optimal compression ratio was obtained by means of fruit flies algorithm.Simulation result shows that the safety level of grounding grid could be improved effectively by using this method.
Keywords:grounding grid  optimal design  lightning transient effect  fruit fly algorithm  electromagnetic transients simulation
