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 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.
Purpose
The intent of this guide is to provide guidance and information pertinent to the grounding practices in WPP collector system for personal safety.The specific purpose of this guide is as follows:— Identify differences between substation grounding (covered under IEEE Std 80™) and WPP collector system grounding.— Establish, as a basis for design, safety limits of potential differences that can exist in a WPP collection system under fault conditions between points that can be contacted by the human body.— Review WPP grounding practices with reference to safety criteria for the design, and provide a procedure for the design of practical grounding systems based on these criteria.— Develop analytical methods as an aid in the understanding and solution of typical voltage gradient problems within a WPP.This guide is primarily concerned with grounding practices within WPPs for 50 Hz or 60 Hz systems. DC systems are beyond the scope of this guide. A grounding system designed as described herein does, nonetheless, provide some degree of protection against steep wave front surges (such as lightning) entering the wind turbine generator (WTG) and passing to earth through its grounding system electrodes
Abstract
New IEEE Standard - Active.The collector system grounding for wind power plants (WPPs) is the primary concern of this guide. This guide is not intended for the WPP 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 consideration, 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 lightning surges is beyond the scope of this document. Similarly, this guide does not cover offshore wind power plants, battery energy storage facilities, solar power plants, or substation grounding
