Sound Power Level of Axial Fans: Noise Simulation for a State Grid Substation

A 5.5 KB Excel dataset contains simulation results for noise prediction at a State Grid CBD substation. Hao Pei authored this dataset, which was last updated on May 8, 2026. The simulation results indicate noise reductions of 6–15 dB(A) from building layout and sound barriers, around 10 dB(A) from sound attenuators, and up to 30 dB(A) from improved enclosure walls.

Use Cases

• Validate noise reduction strategies for substations based on simulated sound attenuation values.
• Benchmark acoustic performance of building layouts and sound barriers using the reported 6–15 dB(A) reduction figures.
• Design comprehensive noise management programs for electrical substations based on the simulation methodology described.
• Reference predicted noise levels for high-voltage substations in sensitive urban environments.

Strengths

• Dataset is small (5.5 KB), facilitating quick download and inspection.
• Simulation results provide specific decibel reduction ranges (e.g., 6–15 dB(A), up to 30 dB(A)).
• Released under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Row count and column definitions are unknown, limiting assessment of data structure and scale.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The dataset's tiny size (5.5 KB) suggests very limited scope, likely summary results rather than raw simulation data.
