摘要
Abstract
Effective grounding device is a significant guarantee for the safe operation of wind turbine.In order to research the problems of grounding dispersion characteristics and resistance reduction efficiency of concrete foundation for wind turbine,the author uses COMSOL Multiphysics simulation software to build a model of concrete foundation for wind turbine,to study the effects of concrete resistivity and soil conditions on the dispersion characteristics of concrete foundation and spark breakdown characteristics of soil,and to propose structural optimization measures for external application of flexible graphite composite electrical grounding material.The results show that:the concrete foundation grounding resistance increa-ses with the increase of concrete(soil)resistivity;the influence of soil resistivity on the concrete founda-tion dispersion characteristics is more obvious than that of concrete resistivity;the spark breakdown vol-ume of the soil around the concrete foundation increases with the increase of concrete(soil)resistivity,while the soil resistivity has a greater effect on it;the external flexible graphite composite electrical grounding material can influence the concrete foundation dissipation characteristics and increase the spark breakdown volume of the soil around it.The results of the study can provide a reference for the design of concrete pile foundations for actual wind turbines.The research results can provide reference for ground-ing design and construction of onshore wind turbines.关键词
