Abstract
In HVDC transmission projects
capacitor is used widely for filtering and reactive compensation and its audible noise is more and more serious. The important premise in noise control of capacitor is to study the capacitor’s audible noise characteristic. In this paper
the related studies are reviewed and the studies can be classified into such four aspects as noise generating mechanism
noise level calculation method
vibration and noise characteristic and noise control
the features of each study aspect are described and analyzed as well as some viewpoints are proposed.
