Abstract
Abstract A high voltage shunt capacitor bank is very important for the normal operation of the power system, especially for the UHVDC transmission in long distance large capacity transmission, and power system networking has an important role. Therefore, its performance response under earthquakes is one of the key concerns. Through the fine finite element simulation modeling of the actual capacitor, the sine beat wave, and the actual earthquake input, the dynamic characteristics and the response index under the earthquake are studied. The results show that the stiffness in the x direction of the capacitor assembly is greater than that in the y direction. The weak position of the model is the root and top of the end insulator and the middle insulator. Under the action of different working conditions, such as X - and Y-El Centro waves, the maximum stress response of the root of the end insulator of the capacitor device is 4.98 MPa, and the safety factor is 3.51, which meets the requirement greater than 1.67.
