Measurement and Analysis on Characteristics of Audible-noise in UHVAC GIS Substations
摘要
Abstract
To understand the characteristics of audible noise in UHV GIS substations,the sound pressure level (SPL) of the main transformers,HV reactors and boundary of the substation were measured in Wuhu 1 000 kV substation.The spectrum distribution,SPL and noise attenuation characteristics were analyzed.The results show that:①The main transformers and the HV reactors have nearly identical SPL around 70 dB(A);②The medium-and low-frequency noises are the main components of the spectrum;③The cooling fun has significant effect on the transformer noise;④Interference phenomenon occurs in the noise transmission processes of the transformers and reactors,in which the noises at 100 Hz and 200 Hz exhibit the most obvious interference;⑤The SPL at boundary is largely influenced by the layout of the noise sources in the substation,the closer the distance between the boundary and the noise source,the more obvious the noise at the boundary of the substation.The obtained results are of significance to noise prediction and assessment of UHV AC substations.关键词
