Standard Development Timeline

This section is maintained by the drafting team during the development of the standard and will be removed when the standard becomes effective.

Development Steps Completed

1.SAR posted for comment November 20, 2013 – December 19, 2013.

2.An earlier draft of this standard was posted for a 45-day comment and ballot period

June 12, 2014–July 29, 2014.

3.PRC-005-3(X) passed a final ballot, which was posted for a 10-day ballot period of

August 27, 2014-September 5, 2014.

Description of Current Draft

The Dispersed Generation Resources Standard Drafting Team (DGR SDT) is posting this version of PRC-005-5 for a 45-day comment period and ballot in the last ten days of the comment period under the new Standards Process Manual (Effective: June 26, 2013).This version is posted for an initial comment and ballot period because changes previously commented on were superseded by non-DGR standard drafting projects that made substantive changes to PRC-005. This version includes all substantive changes recently approved by the NERC Board of Trustees in addition to applicability changes recommended by the DGR SDT.

None.

A.Introduction

1.Title: Protection System, Automatic Reclosing, and Sudden Pressure Relaying

Maintenance

2.Number: PRC-005-45

3.Purpose: To document and implement programs for the maintenance of all

Protection Systems, Automatic Reclosing, and Sudden Pressure Relaying

affecting the reliability of the Bulk Electric System (BES) so that they are kept

in working order.

4.Applicability:

4.1.Functional Entities:

4.1.1Transmission Owner

4.1.2Generator Owner

4.1.3Distribution Provider

4.2.Facilities:

4.2.1Protection Systems and Sudden Pressure Relaying that are installed for

the purpose of detecting Faults on BES Elements (lines, buses,

transformers, etc.)

4.2.2Protection Systems used for underfrequency load-shedding systems

installed per ERO underfrequency load-shedding requirements.

4.2.3Protection Systems used for undervoltage load-shedding systems

installed to prevent system voltage collapse or voltage instability for BES

reliability.

4.2.4Protection Systems installed as a Remedial Action Scheme (RAS) for BES

reliability.

4.2.5Protection Systems and Sudden Pressure Relaying for generator Facilities

that are part of the BES, for generators not identified through Inclusion I4

of the BES definition, including:

4.2.

5.1Protection Systems that act to trip the generator either directly

or via lockout or auxiliary tripping relays.

4.2.

5.2Protection Systems and Sudden Pressure Relaying for

generator step-up transformers for generators that are part of

the BES.

Protection Systems and Sudden Pressure Relaying for

transformers connecting aggregated generation, where the

aggregated generation is part of the BES (e.g., transformers

connecting facilities such as wind-farms to the BES).
