基于改进灰狼算法的接地网腐蚀诊断方法

open access: yesDianci bileiqi
接地网极易受土壤中的因素影响而发生腐蚀,电网络分析法是接地网腐蚀诊断中普遍采用的方法,其存在腐蚀诊断方程求解的高欠定性和寻优算法的不准确、不收敛等问题。本研究将一种改进灰狼算法(OLGWO)应用于腐蚀诊断方程的求解,通过引入反向学习和莱维飞行策略来改善传统灰狼优化算法中存在的初始种群分布不均、容易陷入局部最优等问题,并给出了接地网腐蚀检测的具体流程。通过对模拟接地网的腐蚀诊断结果表明,改进灰狼算法的收敛速度与寻优精度均优于传统优化算法,其诊断最大偏差不超过±5%;再将其应用于贵州某水电站接地网腐蚀诊断中,
