摘要

This study was conducted to identify and quantify the needs (if any) for noise control research applicable to electric utility transformers and reactors to comply with quantitative state noise regulations. The study was accomplished by analyzing available published data, by studying a sample of utility substation drawings, and by assessing various noise-control design approaches. No experimental work was done. The study was restricted to outdoor substations. A model was prepared to predict noise from existing US substations. A sample of 658 substation designs from five utilities was analyzed to refine the above model and to provide a detailed analysis of the configurations, capacities, and noise-control features of present US substations. A typical substation was defined. Advanced transformer designs (low-loss core, amorphous core, SF sub 6 -cooled, vapor-cooled, superconducting) for future substations were reviewed to estimate their noise impacts. Noise abatement options were assessed to define where future noise-control research would be appropriate. It was concluded that: at present, about 5% of the electric utility substations in the US, require an average of 14 dBA of noise reduction to comply with existing noise regulations; estimated cost of compliance is about $200 million; and transformer noise is the dominant problem; current technology can provide the necessary noise control, but it is very costly. Additional research and demonstration programs are recommended to reduce the cost of retrofit noise control treatments for existing substations. It is essential that the electric utility industry be involved in guiding this research. (ERA citation 06:000748)
