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.

What is the IEEE Guide for solar power plant grounding?

IEEE Guide for Solar Power Plant Grounding for Personal Protection IEEE Power and Energy Society Developed by the Energy Development & Power Generation Committee IEEE Std 2778™-2020 IEEE Std 2778™-2020 IEEE Guide for Solar Power Plant Grounding for Personnel Protection Developed by Energy Development & Power Generation Committee of the

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.

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.

Can substations interconnect a solar power plant?

This guide is not intended for the substations to interconnect the plant; however, if the substation is included within the plant, portions of this guide may be applicable. Similarly, this guide does not directly cover small scale solar power plants (such as rooftop type systems), substation grounding, or lightning protection.
