摘要
Abstract
1000 kV AC filter capacitor bank is one of the main equipment of Changji-Guquan±1100 kV UHVDC transmission project,which is used to eliminate harmonics of 1 000 kV side AC system,compensate reactive power and improve voltage quality of the system.A comprehensive summary of the development of 1000 kV AC filter capacitor bank is made from the technical point of view,and the formula for calculating the insulation level(LIWL/SIWL)at the bottom of the capacitor tower is derived through the calculation and analysis of the insulation fit of the capacitor bank by the linear interpolation method,the finite element simulation model is established by using the FEM software ANSYS to validate the seismic performance of the capacitor bank and electric field strength.Noise tests are conducted on different noise reduction schemes for capacitor units,and a comparative analysis is conducted to obtain the most effective,economical,and safe noise reduction scheme.The results show that the design and manufacture of 1000 kV AC filter capacitor bank meets the requirements of±1100 kV UHV DC transmission project,and the capacitor bank can be operated safely and reliably.关键词
