A. Project 2010-13.2 – Phase 2 of Relay Loadability: Generation (PRC-023-3 & PRC-025-1) – Formal
Comment Period, Successive Ballot and Non-Binding Poll for PRC-025-1 – May 24, 2013
Background: FERC Order No. 733 approved PRC-023-1 and directed NERC to address three areas of relay
loadability. This project addresses Phase II of FERC’s directive.
In general, when it comes to “generator interconnection facilities” (as the term is generally used by the SDT),
PRC-025-1 and PRC-023-3 apply the same criteria to load-responsive relays. The difference is in who owns the
protection system. PRC-025-1 applies if the Generator Owner (GO) owns the relays, whereas PRC-023-3 applies
if the Transmission Owner (TO) or Distribution Provider (DP) owns the relays. There are a few exceptions for
unique configurations (see figure 3 in the Guidelines and Technical Basis document) where PRC-023-3 applies to
the GO.
The SDT held a webinar on May 15 to discuss the proposed revisions.
1
PRC-025-1 received 54.65% stakeholder approval in its initial ballot that closed on March 11, 2013. The SDT
previously posted PRC-023-3 for comment with the SAR. Both standards have been revised as a result of
comments received. PRC-025-1 is out for successive ballot and comment. PRC-023-3 is out for comment only.
Note: This is also the project that was the pilot for the Cost Effectiveness Analysis (CEA). The resulting report
has not yet been released.
Summary of Changes
PRC-025-1


Purpose
o
Revised to remove the first occurrence of “generator”


Attachment 1
o
General text revisions
o
Included language to note that the standard does not require the use of any of the protective
functions list in Table 1, Relay Loadability Evaluation Criteria
o
Removed the Planning Coordinator and inserted the Regional Reliability Organization to comport
with the anticipated retirement of MOD-024-1 and MOD-025-1 and the approval of MOD-025-2 in
both the text and Table 1
o
Inserted language to address situations where the Generator Owner may combine both
asynchronous and synchronous generators on a generator interconnection Facility to provide
direction on the evaluation of relay loadability
o
Update the references to no-load tap changes (NLTC) and on-load tap changers (OLTC) to the
generally accepted use of the IEEE terms, deenergized tap changers (DETC) and load tap
changers (LTC)
o
Added an exception to the standard for Protection Systems that detect generator overloads
o
Added an exception to the standard for Protection Systems that detect transformer overloads
o
Made minor editorial edits to Table 1 text for clarity such as replacing “connected to” with
“aggregate” for consistency with other uses
o
Made minor editorial edits to remove hyphens and inserting the word “connected” (e.g.,
Generator step-up transformer [connected] to asynchronous generators)
o
For the application of generator interconnection Facility, reduced the Reactive Power output
calculation from 150% to 120% for consistency with the previous PRC-023-2, Requirement R1,
Criterion 6
PRC-023-3

Applicability
o
The phase “at the terminal of the” was inserted in for each applicable entity of the standard to
create a bright light between the proposed PRC-023-3 and PRC-025-1 standards
2


o
References to the two new Requirements (R7 and R8) was inserted for the applicable Distribution
Provider and Transmission Owner
o
References to the two new Applicability for Circuits (4.2.3 and 4.24) were inserted for the
applicable Distribution Provider and Transmission Owner
o
Applicability 4.2.3 – Circuits Subject to Requirement R7 was added to create a bright line
between the proposed PRC-023-3 and PRC-025-1 standards for the Distribution Provider and
Transmission Owner regarding generator interconnection Facilities
o
Applicability 4.2.4 – Circuits Subject to Requirement R8 was added to create a bright line
between the proposed PRC-023-3 and PRC-025-1 standards for the Distribution Provider and
Transmission Owner regarding generator step-up (GSU) transformers
Requirements
o
Requirement R1, Criterion 6 was removed and replaced by two new proposed Requirements R7
and R8
o
New Requirement R7 applicable to the Distribution Provider and Transmission Owner regarding
generator interconnection Facilities to create a bright line between the proposed PRC-023-3 and
PRC-025-1 in applying settings to load-responsive protective relay for loadability
o
New Requirement R8 applicable to the Distribution Provider and Transmission Owner regarding
generator step-up (GSU) transformer to create a bright line between the proposed PRC-023-3
and PRC-025-1 in applying settings to load-responsive protective relay for loadability.
Attachment A
o

Revised criterion 2.4 to address relays applied at the terminals of generation Facilities in
accordance with NERC Reliability Standard PRC-025-1 for the Planning Coordinator pursuant to
Requirement R6
Attachment C
o
Inserted new attachment to address relay loadability described in Requirements R7 and R8
o
Includes Table 1, Relay Loadability Evaluation Criteria which is the same as the criteria proposed
in PRC-025-1 for generator interconnection Facilities and generator step-up (GSU) transformers
Industry Discussion
B. Project 2007-11 Disturbance Monitoring – Revised SAR Informal Comment Period – June 3, 2013
Background: This project was initiated to address an existing “fill in the blank” standard. FERC did not approve or
remand PRC-002-1 in Order 693 because the standard contained requirements that applied to the Regional
Reliability Organization and did not specifically identify performance requirements for registered entities. FERC
did approve PRC-018-1 in Order 693. Similar to PRC-002-1, PRC-018-1 contained Regional Reliability
Organization requirements, but FERC stated that the requirements are clear enough to be enforced. This project
intends to address FERC concerns in Order 693, specifically the “fill in the blank” aspects in both standards.
A SAR to initiate the project was initially posted in 2007 with a scope of reviewing both standards and merging
them into one replacement standard. A standard drafting team was appointed by the Standards Committee in
2007, who drafted PRC-002-2, which proceeded through an initial ballot period. In 2010 the Standards
Committee decided to prioritize its work, which resulted in moving Project 2007-11 Disturbance Monitoring to
informal development. In its 2013 work plan, the Standards Committee changed the status to formal development
as part of the effort to address pending projects.
The drafting team revised the SAR to focus the project on a results-based approach to the capture of data,
instead of prescriptive requirements on equipment necessary to capture the data. The drafting team believed that
3
it was best to describe the performance requirements (using a risk-based approach) rather than prescribing
necessary equipment. Also, the Reliability Coordinator and Planning Coordinator were added as applicable
entities to ensure that the responsibility for specifying and collecting needed disturbance data can be
appropriately assigned.
An industry webinar is scheduled for May 22, 2013 and workshops are tentatively scheduled for the last week of
July and the first week of August. The locations for the workshops have not yet been determined.

Informal Development Projects
As a part of the 2013 work plan, an informal effort is currently underway to support the resolution of FERC
directives. The informal efforts will support transition to a formal standards development project, which will
include the formal comment and ballot processes that have always occurred. In the specific area of FERC
directives, the possible ways to resolve a directive may be to (i) implement the directive as stated, (ii) provide a
solution that offers an equally efficient and effective method of addressing the concern, or (iii) providing
justification why the directive has been overcome by events and is no longer needed.
There are currently 5 informal development efforts ongoing:

MOD A (ATC, TTC, CBM): MOD-001, -004, -008, -028, -029 & -030 – Ryan Stewart
o These standards are not applicable in the ERCOT region

MOD B (modeling data): MOD-010 through MOD-015 – Steve Noess
o Draft documents circulated to interested parties on MODB distribution list
o Consolidating 6 standards into 2: model data (steady-state, dynamic, short circuit) & model
validation (PC/RC applicability only)
o May 9 Technical Conference briefing (Larisa Loyferman, CenterPoint Energy)

MOD C (demand data): MOD-016 through MOD-021 – Darrel Richardson
o No known activity to date (Norm Muraya, Austin Energy)

