Abstrak

By collecting the sound pressure signals of the aerodynamic noise of the converter transformer fans, the electric field noise of the smoothing reactors and the electric field noise of the DC/ AC filter field in the 800 kV converter station, the spectrum characteristics of the sound pressure signals of different locations are analyzed under the load condition, and the low-frequency and A-weighted sound level noise values of each noise signal are given. It is concluded that the noise of HVDC convert stations covers the low-, mid- and high-frequency bands, and various types of noise signals have similar spectrum characteristics; the low-frequency energy makes up larger portion of the total noise energy, and the low-frequency noise value of the fans is much higher than that of other converter station outdoor equipment under the same test condition.
