Abstract:With the rapid development of intelligent and digital control in power production, there is an urgent need to obtain information on the location of personnel and equipment in three-dimensional work scenarios, in order to determine the distance relationship between people and equipment and generate safety zones. Based on this, this article proposes a safety zone generation technology based on the finite element method in complex work environments. By studying the electric field models on the surface of the human body and different typical design hazardous areas, simulation analysis was conducted on different line electric field 3D models and human 3D models with different complexities. The hazardous areas for high-voltage distribution live work were obtained, and safety area monitoring was generated. For dangerous behaviors, exceeding the safety area, etc., alarm and control systems were triggered to achieve three-dimensional prevention and control measures, such as warning lights, sound alarms, etc. Using finite element method to establish distribution lines and human body models for electromagnetic field simulation, the distribution of electromagnetic fields around transformers and the changes in electromagnetic fields after adding human body models are obtained. By measuring the safe distance, it is determined whether corresponding protective measures need to be taken. The experimental results show that the proposed method effectively achieves precise control of personnel and equipment, providing strong technical support for the implementation of safety control systems.
