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 optimum design of ground-mounted PV power plants?

A new methodology for an optimum design of ground-mounted PV power plants. The 3V × 8 configuration is the best option in relation to the total energy captured. The proposed solution increases the energy a 32% in relation to the current one. The 3V × 8 configuration is the cheapest one.

What is a photovoltaic module (PV)?

The photovoltaic modules (PV) are installed in the solar radiations with sufficient tilted angles on the ground or rooftop to provide electrical energy. The overall conversion efficiency of this technology is very less due to the material properties which are utilized for the PV cells.

Does a ground-mounted photovoltaic power plant have a fixed tilt angle?

A ground-mounted photovoltaic power plant comprises a large number of components such as: photovoltaic modules, mounting systems, inverters, power transformer. Therefore its optimization may have different approaches. In this paper, the mounting system with a fixed tilt angle has been studied.

What rack configurations are used in photovoltaic plants?

The most used rack configurations in photovoltaic plants are the 2 V × 12 configuration (2 vertically modules in each row and 12 modules per row) and the 3 V × 8 configuration (3 vertically consecutive modules in each row and 8 modules per row). Codes and standards have been used for the structural analysis of these rack configurations.

Can a substation interconnect a solar plant?

The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80. This guide is not intended for the substations to interconnect the solar plant; however, if the substation is included within the plant, portions of this guide may be applicable.
