Low-frequency noise from inverters and converters at solar power plant exceeded standards
In recent years, environmental impact assessment (EIA) projects related to solar power facilities have increased rapidly in South Korea, reflecting the country’s efforts to expand renewable energy and reduce greenhouse gas emissions.
Although solar power is considered an eco-friendly energy source, its installation can cause several environmental issues, including land degradation and noise pollution.
This study focused on the low-frequency noise generated by inverters and converters at the Sinan Solar Power Plant.
Noise measurements were conducted according to national standards for environmental noise in residential areas, using an NX-62RT sound level meter over a 24-hour period.
The results indicated that low-frequency noise from inverters exceeded the permissible standards in the 12.5–80 Hz range at short distances, and some frequency bands also exceeded the standards at farther distances.
For converters, noise levels remained within standards below 40 Hz but surpassed the limits above 40 Hz, showing higher levels during nighttime operation.
