Research on Noise Source Location of 110KV Outdoor Substation Based on Acoustic Array

Substation noise control is a key point in the current State Grid substation program. The sound array noise source identification and positioning method is tried to be applied in the actual substation noise test. It is found that in the 110KV outdoor substation, the sound pressure diagram generated based on the two-dimensional plane sound array test can better locate the main noise source, which is the next substation noise and provides an effective basis for noise abatement.
