2 Administrative Items NERC Antitrust Guidelines It is NERC s policy and practice to obey the antitrust laws and to avoid all conduct that unreasonably restrains competition. This policy requires the avoidance of any conduct that violates, or that might appear to violate, the antitrust laws. Among other things, the antitrust laws forbid any agreement between or among competitors regarding prices, availability of service, product design, terms of sale, division of markets, allocation of customers or any other activity that unreasonably restrains competition. Notice of Open Meeting Participants are reminded that this webinar is public. The access number was widely distributed. Speakers on the call should keep in mind that the listening audience may include members of the press and representatives of various governmental authorities, in addition to the expected participation by industry stakeholders. 2

3 Agenda Why PRC-005-X High Level Changes to PRC-005-X Modified NERC Glossary Definition New Standard Only Definition Modified Standard Only Definitions Requirement R1 - Requirement R6 New Table 5 Updated Evidence Retention Next Steps 3

4 Why PRC-005-X This version of PRC-005 is temporarily assigned the numbering PRC-005-X because PRC-005 will be modified by two drafting teams simultaneously: Project (Protection System Maintenance and Testing (PSMT)) and Project (Standards Applicability for Dispersed Generation Resources (DGR)) during Separating the changes is necessary for the DGR Standards Drafting Team (SDT) to petition applicable governmental authorities for the applicability changes on a separate timeframe from the other technical changes in this version of PRC-005-X. Coordination between both DGR SDT and PSMT SDT. 4

5 High Level Changes to PRC-005-X In response to Order No. 758, the SDT added Sudden Pressure Relaying by: Defining a new term (Sudden Pressure Relaying); Modifying Protection System Maintenance Program (PSMP) definition to add Sudden Pressure Relaying; Revising the Applicability elements; Adding Table 5 to address minimum maintenance activities and maximum maintenance intervals; and Revising the previous Implementation Plan. 5

6 High Level Changes to PRC-005-X The PSMT SDT reconsidered its position on including Balancing Authorities in PRC-005-X; therefore, the SDT: Added Balancing Authority to the Applicability; Added a requirement that Balancing Authorities notify their Transmission Owners, Generator Owners, and Distribution Providers of the gross capacity of the largest BES generating unit within the Balancing Authority Area; and Revised Requirements R3 and R4 to address the obligations previously expressed in the Implementation Plan regarding initial maintenance of Automatic Reclosing that becomes newly applicable at future times, and removed these elements from the Implementation Plan. 6

7 High Level Changes to PRC-005-X The SDT addressed U.S. Office of Management and Budget concerns raised in the PRC FERC proceeding on the lengthy document retention periods by consulting with NERC Compliance Operations staff and reducing the required data retention periods. The SDT made changes to the Supplementary Reference and FAQ Document to reflect the changes in the standard. 7

8 Modified NERC Glossary Definitions NERC Glossary of Terms Definition: Protection System Maintenance Program (PSMP): An ongoing program by which Protection System components are kept in working order and proper operation of malfunctioning components is restored. A maintenance program for a specific component includes one or more of the following activities: Verify Determine that the component is functioning correctly. Monitor Observe the routine in-service operation of the component. Test Apply signals to a component to observe functional performance or output behavior, or to diagnose problems. Inspect Examine for signs of component failure, reduced performance or degradation. Calibrate Adjust the operating threshold or measurement accuracy of a measuring element to meet the intended performance requirement. Suggested Change: Protection System Maintenance Program (PSMP): An ongoing program by which Protection System, Automatic Reclosing, and Sudden Pressure Relaying Components are kept in working order and proper operation of malfunctioning components is restored. A maintenance program for a specific Component includes one or more of the following activities: Verify Determine that the Component is functioning correctly. Monitor Observe the routine in-service operation of the Component. Test Apply signals to a Component to observe functional performance or output behavior, or to diagnose problems. Inspect Examine for signs of Component failure, reduced performance or degradation. Calibrate Adjust the operating threshold or measurement accuracy of a measuring element to meet the intended performance requirement. 8

9 New Standard Only Definitions Standard Only Definition: Sudden Pressure Relaying is a new term. Suggested Change: Sudden Pressure Relaying: A system that trips an interrupting device(s) to isolate the equipment it is monitoring and includes the following Components: Fault pressure relay a mechanical relay or device that detects rapid changes in gas pressure, oil pressure, or oil flow that are indicative of Faults within liquid-filled, wire-wound equipment Control circuitry associated with a fault pressure relay 9

10 Modified Standard Only Definitions Standard Only Definition: Unresolved Maintenance Issue: A deficiency identified during a maintenance activity that causes the component to not meet the intended performance, cannot be corrected during the maintenance interval, and requires follow-up corrective action. Component Type: Either any one of the five specific elements of the Protection System definition or any one of the two specific elements of the Automatic Reclosing definition. Suggested Change: Unresolved Maintenance Issue: A deficiency identified during a maintenance activity that causes the Component to not meet the intended performance, cannot be corrected during the maintenance interval, and requires follow-up corrective action. Component Type: Any one of the five specific elements of a Protection System. Any one of the two specific elements of Automatic Reclosing. Any one of the two specific elements of Sudden Pressure Relaying. 10

11 Modified Standard Only Definitions NERC Glossary of Terms Definition: Component: A Component is any individual discrete piece of equipment included in a Protection System or in Automatic Reclosing, including but not limited to a protective relay, reclosing relay, or current sensing device. The designation of what constitutes a control circuit Component is dependent upon how an entity performs and tracks the testing of the control circuitry. Some entities test their control circuits on a breaker basis whereas others test their circuitry on a local zone of protection basis. Thus, entities are allowed the latitude to designate their own definitions of control circuit Components. Another example of where the entity has some discretion on determining what constitutes a single Component is the voltage and current sensing devices, where the entity may choose either to designate a full three-phase set of such devices or a single device as a single Component. Suggested Change: Component Any individual discrete piece of equipment included in a Protection System, Automatic Reclosing, or Sudden Pressure Relaying. 11

12 Modified Standard Only Definitions NERC Glossary of Terms Definition: Countable Event A failure of a Component requiring repair or replacement, any condition discovered during the maintenance activities in Tables 1-1 through 1-5, Table 3, and Tables 4-1 through 4-2, which requires corrective action or a Protection System Misoperation attributed to hardware failure or calibration failure. Misoperations due to product design errors, software errors, relay settings different from specified settings, Protection System Component or Automatic Reclosing configuration or application errors are not included in Countable Events. Suggested Change: Countable Event A failure of a Component requiring repair or replacement, any condition discovered during the maintenance activities in Tables 1-1 through 1-5, Table 3, Tables 4-1 through 4-2, and Table 5, which requires corrective action or a Protection System Misoperation attributed to hardware failure or calibration failure. Misoperations due to product design errors, software errors, relay settings different from specified settings, Protection System Component, Automatic Reclosing, or Sudden Pressure Relaying configuration or application errors are not included in Countable Events. 12
