Desarrollo de un algoritmo para el dimensionamiento de protección contra descargas atmosféricas en edificaciones basado en el método de la esfera rodante.

This study focused on the development of an algorithm that allows for sizing protection against atmospheric discharges in buildings, based on the rolling sphere method, which enables user data input through the graphical interface. Its methodology begins with gathering project information, including factors like lightning flash density and dimensions of the structure, among others. Risk factors are calculated using the Risk Assessment software to identify potential scenarios such as loss of human lives, disruption of public services, damage to cultural heritage, and economic losses. If corrections are necessary, this process is followed; otherwise, the location is protected: calculation of soil resistivity using IEEE Std. 81, application of the rolling sphere method according to IEC 662305-3, grounding system based on IEEE Std. 142 and IEEE Std. 80. To determine the behavior of a lightning discharge on the already protected building, calculations of electrical equivalents for the mesh, copperweld rod, horizontal, and vertical conductors are established. Using the obtained results, a circuit is created in ATPDraw, linked to Python, which provides waveform graphs of the current across various protection subsystems. To complete and validate the process, risk factors are recalculated. Algorithm validation is determined by its margin of error, which tends to zero when inputting data from proposed exercises based on standards such as IEC and IEEE. This demonstrates the effectiveness of the proposed algorithm.
