Simulation Analysis of Electromagnetic Vibration of Shunt Reactor Based on AC and DC

Shunt reactors in the power system play a crucial role in enhancing power load capacity and improving voltage stability. However, the electromagnetic vibrations they generate can lead to equipment damage, energy loss, and stability issues within the system. Therefore, in-depth research is required. This paper aims to investigate and validate the electromagnetic vibration characteristics of shunt reactors in the power system through simulation analysis. Based on this, the paper deduces the electromagnetic-mechanical coupling vibration equation, calculates the electromagnetic vibration of the iron core under AC and DC excitation, and analyzes the effects of the displacement, and acceleration of the AC iron core. Distribution cloud pattern and change characteristics; the response law of the electromagnetic vibration parameters of the iron core when different DC components are injected is studied, and the time-frequency domain curve characteristics of the acceleration and displacement parameters at the midpoint of the top of the upper iron yoke are analyzed. The electromagnetic vibration characteristics of shunt reactor iron core are obtained, which provides guidance for the development of vibration monitoring system and has reference value for International Conference on Intelligent Power and Systems.
