Proposal information to include, objective, methods, results, and conclusion: Solar photovoltaics (PV) power plants are playing a greater role in the generation of power in North America, and several factors expect this increased growth in the coming years. As PV generation is modular, some facilities range from 5 -20 MW and interconnect with a utility’s distribution circuit. Larger facilities can provide 300 MW or more, are often designed with their own collector substation, and interconnect with transmission level voltages. This discussion, given by David Lewis, PE, Grounding and Power Systems at EasyPower, steps through the challenges to accurately assessing if the grounding system performance meet IEEE Std 80 personnel safety criteria. Transferred voltages, fault current split, regional modeling, and other analysis concerns will be addressed.
