| 中文摘要 | 敏感电子设备的广泛应用使得雷击建筑物产生的电磁兼容和电磁干扰(EMC/EMI)问题备受关注。雷击建筑物防雷系统暂态过程的分析是研究雷击过程对建筑物产生影响的基础,其中电路方法是雷击建筑物暂态问题最为常用的分析方法,防雷系统电气参数计算是电路方法的重要环节。为此研究了防雷系统电气参数的快速计算方法,将电气参数计算公式中积分部分推导成含有电位格林函数双重线积分的形式,并给出了其解析计算方式。这种方法避免了耗时的数值积分运算,计算速度显著提高。选取具体实例采用上述两种方法进行了计算和比较,验证了该方法的计算速度和计算效果。对于选取的实例,采用所提出的方法速度可提高100倍以上。对于大型防雷系统,该方法也能使计算速度大为提高,便于开发出大型建筑物防雷计算软件。; The wide use of the sensitive electronic equipment makes the electromagnetic compatible,and the electromagnetic interference(EMC/EMI) problems caused by the lightning stroke are widely concerned.Circuit method is commonly used to analyze the transient problems caused by the lightning stroke,and the parameter calculation of lightning protection systems is the important segment of the circuit method.We put forward the fast algorithm for calculating the electrical parameters of building lightning protection systems,and analyzed the integrals in the parameter calculation using the double line integral of the Green function for electric potential,which could be evaluated with the closed-form expression to avoid the time-consuming numerical integrals.Accordingly,the parameters of the building lightning protection system could be calculated in a short time.The speed and efficiency of the newly-proposed method were validated via comparing the results from other literatures and methods.Results show that,using the method proposed can increase the speed of above one hundred times more than numerical method.The calculation speed also can be increased greatly for the large-scale lightning protection system,which makes it available to develop the lightning protection calculation program for large-scale building. |
