As the main noise source of HVDC, converter transformer converter's noise prediction precision and the choice of control methods will directly influence the level of noise prediction and management effect for converter station. Through the systematic study on the noise-generation mechanism, frequency spectrum, the type of sound source, noise control measures and so on, the paper highlights the BOX-IN...
The noise problem of UHVDC coverter stations which is more severe than that of HV ones, gets more and more attention. UHVDC converter stations noises mainly caused by converter transformer, smoothing reactor and capacitors and reactors of AC filter sets. Noise control measures must be taken by proper site selection, optimum general layout, sound source reduction, fully enclosed box of converter transformers,...
