An Overview of the DC Wiring System Design Issues in the SMUD Phase I Photovoltaic Power Plant

The DC wiring system of a photovoltaic power requires a number of safety features that result from the unique aspects of. photovoltaic devices. This paper presents an overview of the DC wiring system design developed for the Sacramento Municipal Utilities District (SMUD) Phase I photovoltaic power plant. The specific challenges that photovoltaic devices present to a power plant designer are identified along with the specific solutions adopted in the SMUD design.
