Standard for Generating Station Grounding

665-1995 发布历史

Overview This guide was developed to identify grounding practices that have generally been accepted by the electric utility industry as contributing to effective grounding systems for personnel safety and equipment protection in generating stations. It provides a guide for the design of generating station grounding systems and for grounding practices applied to generating station indoor and outdoor structures and equipment@ including the interconnection of the station and substation grounding systems. Guidance for the grounding of control and instrumentation equipment in generating stations can be found in IEEE Std 1050-1989. 1 Generating station grounding designs are complicated by considerations such as physically large outdoor areas with multiple buildings and associated transfer voltages@ grounding effects of buried infrastructure@ rotating electrical apparatus@ large indoor areas@ auxiliary systems with multiple voltage levels@ and the need for increasingly ?clean? signal ground sources for control systems. This guide has been developed in recognition that the complexities of generating stations are such that the generally accepted techniques and programs for the design of electrical substation grounding systems for safety may not address all of the issues. While these complexities may be suitably analyzed with the computerized methods that are available@ this guide presents a manual calculation method based on the principles presented in IEEE Std 80-1986. It is not intended that this document provide grounding test methods or quantitative analysis of the effects of lightning surges. This document should not be interpreted as requiring any speci?c design for a particular installation; instead@ it is a guide to the process and special techniques that the designer should recognize and consider. The necessary supporting detail is to be found in other relevant standards and documents; these are referenced in the text where appropriate. 1 Information on references can be found in clause 2
