雷击风险评估中位置因子Cd的取值研究

摘要

Based on the lastest edition of IEC 62305-2 2010,we analysis the value methods of factor Cd,for the values of Cd discrete poorly considered,in order to improve the accuracy of the lightning risk assessment,numerical fitting was used to get the curve of the continuous values.%基于最新发布的IEC 62305-2 2010[1],对参数Cd的取值方法及优化进行分析,并针对Cd取值离散考虑不周全的情况,通过Matlab数值模拟的方法获得了连续取值的曲线,以提高风险评估的准确性.
