Abstract :
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 technology and verifies the effect compared with sound barriers technology by SoundPlan. According to the field test, the result indicates that the noise reduction quantities of BOX-IN equipment achieves about 20dB(A) corresponding to the theoretical calculation, which will provide theoretical basis for improving the noise prediction precision of HVDC furtherly.
