摘要
针对接地网表面电位的不均匀分布,不能很好地保障人身和设备的安全,采用粒子群算法对两层土壤接地网进行优化设计。首先建立接触电压达到最小值时的目标函数,再以最优压缩比作为优化目标。通过与文献所提供的算例进行比较,结果表明,应用粒子群算法可以得到接地网导体不等间距布置的最优形式。
According to the uneven electric potential distribution of the ground grid surface, which not very good to protect the personal and equipment safety, optimization design of the two layer soil grounding grid is carried out by using the particle swarm algorithm. The optimization function regards the best compression ratio as the optimization goals, which established with the objective of maximum distribution of the surface potential and minimal potential difference. The result of comparing with calculation example from the references shows that, the optimal form of grounding grid conductors ranging spacing layout can be obtained by using partical swarm algorithm.
