Abstract

Abstract: The main structure of the substation post-equipment is a typical wind-sensitive structure, which is high and flexible. In order to ensure the safety and stability of the structure, it is necessary to conduct a modal analysis of the main structure of the substation post equipment, which in turn provides a basis for the analysis of wind vibration characteristics of the structural system. This paper analyzes the self-oscillation frequency and vibration pattern of the main structure of a substation in Inner Mongolia based on ABAQUS, compares them with the measured wind response modal results to verify the reliability of the numerical simulation results and finds that the low-order natural frequency of the main structure of the substation pillar-type equipment is between 0-2 Hz, and the frequency in the opening state is lower than the state of closing soon.
