青海共和光伏工业园区土壤电阻率变化特征分析

Analysis on Variation Characteristics of Soil Resistivity in Qinghai Gonghe Photovoltaic Industrial Park

土壤电阻率与土壤的结构、土质的紧密程度、湿度、温度以及土壤中可溶性电解质有关,而接地电阻与土壤电阻率、接地装置的结构和布置有关。通过研究青海共和光伏工业园区土壤电阻率时间及空间上的分布特征,分析研究土壤电阻率在不同季节和不同土质条件下的变化规律,探讨科学布设接地装置、有效加大接地装置泄流量的措施,为光伏电站接地工程建设提供技术依据。

Soil resistivity is related to soil structure,soil compactness,humidity,temperature and soluble electrolyte in soil,while grounding resistance is related to soil resistivity,structure and arrangement of grounding devices.By studying the temporal and spatial distribution characteristics of soil resistivity in Qinghai Gonghe PhotovoltaicIndustrial Park,analyzing and studying the changing law of soil resistivity in different seasons and different soilconditions,and discussing scientifically laying grounding devices and effectively increasing the leakage of grounding devices.To provide technical basis for the construction of photovoltaic power station grounding engineering.
