Renewable Energy (Solar/Wind/Tidal) Plant Grounding Analysis/Earthmat Design

Solar Plant

As solar plants are usually very large in size, large spacing soil resistivity measurements have to be carried out. The worst fault is usually a high voltage fault at the adjacent switching station rather than a low voltage fault at the photovoltaic system location. Steel piles supporting the solar panels should be interconnected and connected to the photovoltaic system grounding network in order to achieve safety for the entire area without the application of crushed rock. MultiGroundZ or MultiFields are appropriate software packages for carrying out solar power plant grounding study.

Wind Turbine Farm

The grounding analysis of wind farms is quite complex due mainly to the distributed nature of those installations. Generation occurs at several disparate locations (the wind turbines) which are all regularly serviced by personnel and must be equipped with adequate grounding systems. Since the performance of a grounding system is a function of the nature of the soil near the surface of the earth, the electrical characteristics of the soil must be accurately determined at each wind turbine location in order to be able to properly analyze each site.

Grounding study of a wind turbine farm requires simultaneous analysis of the grounding systems, short-circuit fault current computations and fault current distribution in soil, shield wires, neutrals and power cable shields and armors. Multifields is recommended these studies and analysis. Multifields can also perform the transient performance analysis of a wind turbine struck by lightning.
