Abstract: 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 are identified. 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, is provided.

Keywords: electric utilities, generating stations, grounding, grounding systems, personnel safety,

substation grounding systems

IEEE Standards

documents are developed within the Technical Committees of the IEEE Societies

and the Standards Coordinating Committees of the IEEE Standards Board. Members of the com-

mittees serve voluntarily and without compensation. They are not necessarily members of the Insti-

tute. The standards developed within IEEE represent a consensus of the broad expertise on the

subject within the Institute as well as those activities outside of IEEE that have expressed an inter-

est in participating in the development of the standard.

Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply

that there are no other ways to produce, test, measure, purchase, market, or provide other goods and

services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the

time a standard is approved and issued is subject to change brought about through developments in

the state of the art and comments received from users of the standard. Every IEEE Standard is sub-

jected to review at least every Þve years for revision or reafÞrmation. When a document is more

than Þve years old and has not been reafÞrmed, it is reasonable to conclude that its contents,

although still of some value, do not wholly reßect the present state of the art. Users are cautioned to

check to determine that they have the latest edition of any IEEE Standard.

Comments for revision of IEEE Standards are welcome from any interested party, regardless of

membership afÞliation with IEEE. Suggestions for changes in documents should be in the form of a

proposed change of text, together with appropriate supporting comments.

Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as

they relate to speciÞc applications. When the need for interpretations is brought to the attention of

IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-

resent a consensus of all concerned interests, it is important to ensure that any interpretation has

also received the concurrence of a balance of interests. For this reason IEEE and the members of its

technical committees are not able to provide an instant response to interpretation requests except in

those cases where the matter has previously received formal consideration.

Comments on standards and requests for interpretations should be addressed to:

Note: Attention is called to the possibility that implementation of this standard may

require use of subject matter covered by patent rights. By publication of this standard,

no position is taken with respect to the existence or validity of any patent rights in

connection therewith. The IEEE shall not be responsible for identifying all patents for

which a license may be required by an IEEE standard or for conducting inquiries into

the legal validity or scope of those patents that are brought to its attention.

Introduction

(This introduction is not part of IEEE Std 665-1995, IEEE Guide for Generating Station Grounding.)

This guide is intended to complement the recommendations and information presented in existing grounding

practices for industrial and commercial power systems (IEEE Std 142-1991, IEEE Recommended Practice

for Grounding of Industrial and Commercial Power Systems), substations (IEEE Std 80-1986, IEEE Guide

for Safety in AC Substation Grounding), and measurements (IEEE Std 81.2-1991, IEEE Guide for Measur-

ment of Impedance and Safety Characteristics of Large, Extended or Interconnected Grounding Systems),

while drawing particular attention to speciÞc requirements for generating stations.

This guide was prepared by a Task Force of the Grounding Practices Working Group. The working group is

part of the Station Design Subcommittee and was sponsored by the Energy Development and Power Gener-

ation Committee of the IEEE Power Engineering Society. Comments were also solicited from the following

groups:

Ñ National Electric Safety Code

Committee

Ñ Power System Communications Committee

Ñ Power System Instrumentation and Measurements Committee

Ñ Power System Relaying Committee

Ñ Transmission and Distribution Committee

Ñ Surge Protective Devices Committee

Ñ Substation Committee

Ñ Industry Applications Society

Ñ Edison Electric Institute

摘要：

IEEE Std 665-1995 (2001) 是一项由电气与电子工程师协会（IEEE）发布的标准，标题为《IEEE Guide for Generating Station Grounding》。该标准最初于1995年发布，并于2001年进行了确认和重新批准，旨在为发电站的接地系统设计、安装和测试提供全面指导。它涵盖了接地系统的安全性能要求、接地电阻的测量方法、接地装置的布局与材料选择，以及故障电流分布与电位梯度控制的工程实践。该标准适用于火力、水力、核能及可再生能源发电站，是电力工程师在评
