A specific modeling of ground protection system for wind power plants

Abstract

This paper presents specific combined protection of grounding systems that can be applied for wind power plants. The proposed prototype design is a combination of the ferrite ring technique, surge arrester models, as well as voltage surge protector, which impacts dampen tension more effectively by building a dedicated line with a separate model. The proposed model is 100 m in width with a depth of 2 m from the soil which is based on the IEC-61643-12 study. The transmission line approach model is used to obtain a description of the behavior of lightning occurring in the soil. The simulation results show the proposed design can be applied effectively.
