NERC Standards Violations 3
Overview PRC-005-1 • – Current Issues / Best Practices PRC-005-2 • – Standard – Implementation schedule Future PRC-005 • – Version 3 automatic reclosing relays – Version 4 sudden pressure relays 4
PRC005-1 Current issues / Best practices No basis for time intervals • – Use the table in PRC005-2 as the basis for time intervals (The SPP RE has approved using the table in PRC-005-2 as the basis for time intervals) – IEEE guides can be used for the specific equipment, manufacturer recommendations, as well as experience with the elements Program identified an action that was not taken • – Make sure you review/train your program thoroughly – Contractors/employees understand program 5
PRC005-1 Current issues / Best practices Cont.. No test for identified needed test date (Missing records) • – Invoices, work management system entries, processed work orders, relay and battery test sheets Too much time between tests • – Identify the Max intervals and build out schedules to cover protection elements – List intervals that have some flexibility. eg. If the max interval is every three years, set your interval to be every 34 months (not to exceed 36 months) 6
PRC005-1 Current issues / Best practices Cont.. DC circuitry, PTs/CTs, carriers, and other elements not • tested – List needs to include total population of protection elements – An understanding of what encompasses the “protection system” based on the NERC definition should be implemented – Per the NERC Glossary of Terms - the components are: Relays (electro-mechanical and microprocessor); Associated communication systems; DC control circuitry; Voltage and current sensing devices (PTs & CTs); and station batteries 7
PRC005-1 Current issues / Best practices Cont.. Continuously monitored elements not continuously • monitored – Detailed listing of elements and annual review should ensure that elements are categorized correctly Not all relays in substation actually tested • – Make sure that new equipment is addressed – Include a “New Elements Process” in your program If device’s status is monitored, but not actually monitored • – Screenshots to show alarms, etc. can be provided 8
PRC005-1 Current issues / Best practices Cont.. Relays tested, but no summary of what was done to test • – Records retention should include a summary of the actual actions with the result of the test. Not all Substations included in relay database • – As part of new substation build-out, make sure that the substation gets added to the maintenance and testing program – Thoroughly check your system to include all protection equipment in the list 9
Summary of Best Practices Review your programs thoroughly • – Cover total population of all protection elements Use the new definition when training employees and contractors – Walk the Talk (if program includes action make sure you are doing it) I.E. if your program says you will test each battery cell, test each cell If you want to use a lockout to test the relay once and then test signals to the relay after that, make sure you say it in your plan that you do it that way. 10
Summary of Best Practices Time intervals • – Detailed Schedule – Basis (PRC-005-2 table, IEEE, manufacturers, real world experience) Records retention • – 3-? year data retention depending on when last test was performed and the type of protection element – Program, completed test sheets, summary of test procedure, work orders, signatures – Keep records for legacy until full implementation (PRC-005-2) 11
PRC-005-2 How it affects you and Implementation dates Approved by FERC (Order 793) • Regulatory Effective Date: February 24, 2014 • First quarter following regulatory approval: April 1, 2014 • 12
PRC 005-2 How it affects you Protective System and Maintenance Program Updates • – Performance based (R2 & R4 ) vs. Time based selection (R3) – Monitored vs. Unmonitored No maintenance for Monitored elements Documentation for Monitored elements – Legacy Documentation (phased in approach) Whether each component has last been maintained according to PRC-005-2 or under PRC-005-1b, PRC-008-0, PRC-011-0, or PRC-017-0. Legacy standards will be retired following full implementation of PRC- 005-2. 13
PRC 005-2 How it affects you cont.… New definition of Protective System • Protective relays which respond to electrical quantities – Communications systems necessary for correct operation of protective – functions Voltage and current sensing devices providing inputs to protective relays – Station dc supply associated with protective functions (including station – batteries, battery chargers, and non-battery-based dc supply) Control circuitry associated with protective functions through the trip coil(s) – of the circuit breakers or other interrupting devices 14
