Abstract

Power capacitor is the main noise source in the HVDC converter station. In the design stage of the HVDC converter station

the impact of the noise generated by the power capacitor towers on the surrounding environment must be accurately predicted and calculated. In this paper

a kind of directivity algorithm calculation method for far field noise radiation directivity is proposed on the basis of superposition principle of coherent sound sources and attenuation analysis of acoustic wave propagation and the typical capacitor stack is simulated and calculated. It is shown by the result that the directivity obtained by the calculated of simplified coherent sound source superposition formula can well simulate the noise radiation characteristics of the power capacitor tower.
