风电装置下地电阻率背景噪声分析
Analysis of background noise of georesistivity under the influence of wind power devices
摘要
Abstract
Aiming at the electromagnetic interference caused by wind power devices on the geoelectrical observation environment,two types of wind towers with metal towers and cement towers were selected,and multiple sets of observation devices and instruments were deployed around them to collect observation data.Data analysis was conducted using the data processing methods specified in national standards for non-power-frequency and power-frequency electromagnetic disturbance,the FastICA algorithm and FFT spectrum analysis.This systematically evaluated the electromagnetic disturbance of georesistivity under different tower materials,observation device configurations and distances from the towers.The results indicate that when the center point of the observation device is 30 m away from the wind turbine,the electromagnetic disturbance does not meet national standard requirement,while the electromagnetic interference meets national standards at a distance of 60 m.The FastICA method shows that the ambient interference noise in the test environment is relatively limited.Combined with FFT spectrum analysis,it shows that the electromagnetic interference generated by the wind power installations is primarily concentrated in the 0.005 Hz frequency band.This study provides a scientific basis and technical support for determining the avoidance distance from wind power installations for future geoelectric station construction and the protection of the observation environment.关键词
