This guide is primarily concerned with the collector systems grounding for wind power plants. This guide is not intended for the wind power plant substation, however since the substation is typically interconnected with the collector system, its design might affect or be affected by the collector system. With proper caution, the methods described herein could be used in determining the impact of the collector system on substation safety and vice versa. Quantitative analysis of the effects of… read more lightning surges is beyond the scope of this document. Similarly, this guide does not cover off-shore wind power plants, solar power plants or substation grounding. read less

This recommended practice defines the principles and procedures for start-up, normal operation, shutdown, daily operation, and maintenance during normal and emergency conditions for a 300 MW to 600 MW pulverized coal-fired boiler and its main auxiliary equipment. This recommended practice applies to 300 MW to 600 MW pulverized coal-fired boilers with a balanced draft, including natural circulation and forced circulation; subcritical and supercritical once-through boilers; tangential-fired… read more boilers; opposed-fired boilers; and so on. For specific applications, an additional document needs to be formulated by users based on this recommended practice to cover detailed procedures or normally so-called "operation code," together with the instructions of manufacturers and the experiences derived from normal operation practice. read less

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. 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. Similarly, this guide… read more does not directly cover small-scale SPPs (such as rooftop type systems), substation grounding, or lightning protection. read less
