Abstract

The invention provides a method of correcting and measuring wind power plant soil resistivity. The method of correcting and measuring wind power plant soil resistivity includes the steps: selecting one measurement center point; setting two groups of measurement electrodes which are symmetrical with the measurement center point, and utilizing the at least two groups of measurement electrodes to measure the wind power plant soil resistivity; exchanging the two groups of measurement electrodes to carry out correction measurement so as to obtain the corrected wind power plant soil resistivity; andwhen the error between the wind power plant soil resistivity and the corrected wind power plant soil resistivity is less than the preset value, determining the average value of the wind power plant soil resistivity measured many times as the wind power plant soil resistivity. The method of correcting and measuring wind power plant soil resistivity has the advantages of being accurate in measurement and being low in measurement difficulty.

Description

technical field [0001] The invention relates to the field of wind farm resistivity measurement, in particular to a method for correcting and measuring wind farm soil resistivity. Background technique [0002] Due to its cleanliness, renewability and abundant reserves, wind power resources have been vigorously developed in China in recent years. Wind farms occupy a small area and are a promising clean energy source. Most wind farm substations are built in hilly areas with complex soil structures and high grounding resistance. The characteristics of complex soil structure and high resistivity increase the difficulty of measuring the soil resistivity of wind farms. So it is very necessary to study a soil resistivity measurement and correction method suitable for wind farms. Contents of the invention [0003] The invention provides a method for correcting and measuring the resistivity of wind farm soil, which overcomes the difficulty of measuring the soil resistivity of wind...
