What is a solar substation grounding guide?

Abstract: This guide is primarily concerned with the grounding system design for photovoltaic solar power plants that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80.

Do PV systems need grounding?

It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. This article covers grounding in PV systems, which differs slightly from standard grounding systems.

What is the purpose of the grounding system design guide?

Scope: This guide is primarily concerned with the grounding system design for ground-mount photovoltaic (PV) solar power plants (SPPs) that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80.

Does this guide cover small scale solar power plants?

Similarly, this guide does not directly cover small scale solar power plants (such as rooftop type systems), substation grounding, or lightning protection.

How do you design a grounding system?

sections discuss an approach to design a grounding system and perform this analysis. SPP. A common design consists of an interconnected grounding system with very large grid spacing (in excess of 100 m (350 ft) (see Lewis and Schaerer [B3]). The spacing often is determined in order to surround each 1 MW to 4 MW block of PV generation.

How do you validate a grounding system for a large spp?

The use of software is often a requirement to validate the performance of a grounding system for a large SPP. Even using software, complete modeling of the entire system can be difficult. The following sections discuss an approach to design a grounding system and perform this analysis. SPP.
