Abstract
With the rapid development of electrical engineering, the design and optimization of grounding system has become an important part of ensuring the safe operation and personal safety of electric power equipment. This study aims to propose a grounding system design scheme based on the design of multiob jective optimization system, in order to improve the reliability and economy of the system. By analyzing the key factors such as soil resistance, grounding grid structure and fault current distribution, a comprehensive evaluation model of grounding resistance, contact voltage and step voltage is constructed, and a genetic algorithm is introduced to solve the model. The results show that the proposed method can significantly reduce the grounding resistance and reduce the material cost while meeting the safety standards. Compared with the existing methods, this scheme has more adaptability and higher optimization efficiency, and shows significant advantages especially in complex geological conditions.
