NERC Test Questions- 100% verified Q&A.

NERC Test Questions- 100% verified Q&A What percentage of load gives a 1 Hz change in an island condition? 6-10% (Think 6-10 day island vacation) If ACE is Zero but system Hz is off, what should a system operator do? Nothing! ACE bias and interchange schedule will improve frequency If ACE is Zero, why not adjust generation to help frequency? Could overload equipment, this is a NERC violation When restoring from blackout condition, what should be done with load? All load breakers should be opened, load should be restored in a controlled manner not to exceed 5% of current available gen They will manage, alarm, test and/or actively monitor, especially emergency comm routine equipment) Only for internal operation, Operation of the BES requires comms in English Ensure BA, TO, GO, and RC have comms and capability to use them for addressing Who should a BA or TO notify if they are aware of any condition that could threaten What's the point of COM-001? Each TO, BA, RC and NERCNet Use Orgs need to have good comms Where do they need to have comms? Internal, Between RC, TO and BA, Other RC, TO, BA and authorities Where applicable comms should be ______ and _______ routed. Redundant and Diversely routed, just in case something fails How do we know comms will be good? facilities and equipment (non- When can languages other than English be used? What is required so operation during a loss of comms will be ensured? Written operating instructions and procedures What is the point of COM-002? emergency and that operators are trained to use them area reliability or when shedding load? Notify their RC and any other potentially affected BA or TO 00:0301:28 How should directives be issued by an RC, TO or BA? In a clear, concise and definitive manner, using 3 part(way) communications Who is required to create a blackstart restoration plan? Who approves it? Transmission Operators; Its RC When is the blackstart condition finished? When the choice of the next load to be restored is not driven by frequency and voltage control Who directs the procedure for restoring interconnection between Tos? RC What must be done prior to implementing changes in a restoration plan? The parties invloved must be told of changes to their role and specific tasks prior to implementation. How often must the plan be confirmed given no changes were made? TO annually review the plan and report to RC After a system modification is made, how long does the TO have to update restoration plans? 90 days Where is a copy of the restoration plan required to be kept? Main and backup control rooms What must be done on the restoration plan every five years? Analyze the plan through actual events, steady state and dynamic simulations or testing that the plan can work as intended. How often must a Blackstart Resource verify it can meet real and reactive power requirements of its cranking path and intial load? Every 5 years How often must the location of loads required to control voltage and Hz in a blackstart be verified within operating limits? Every 5 years How often is the capability of generating resources required to control voltage and Hz in a blackstart condition verified? Every 5 years What should a TO use if the restoration plan cannot be executed? Use its restoration strategies Under what conditions can a TO resynchronize with its neighboring TO? Only with RC approval or with the established procedures of the RC What is the point of Blackstart Resource testing? To ensure the resource is capable of me4eting the requirements of the restoration plan How often must a Blackstart Resource be verified at a minimum? Once every 3 years Name two requirements when testing a Blackstart Resource: Ability to start with no BES support and remain energized without the rest of the system; The ability to energize a bus What is the frequency that system restoration training for operators is required? Annually What is the purpose of annual operator system restoration training? To assure proper execution of its restoration plan Name 4 things required in annual operator system restoration training: System restoration plan including coordination with RC and GO; Restoration Priorities; Building of cranking paths; Synchronizng How often and how much training is required for field switching personnel who are included in the system restoration plan? Minimum 2 hrs every 2 years When must a TO or GO participate in RC restoration drills, exercises or simulations? As requested by the RC What is a Blackstart Resource Agreement? This is an agreement between a TO and GO that includes the terms and conditions of the use of the Blackstart Unit; e.g. procedures, protocols, testing requirements What is required by each GO for their Blackstart Resources? Documented procuedures for starting each resource and energizing a bus Who must a GO notify if a Blackstart Resource ability to perform its function is changed? The TO who holds the agreement What is the time requirement for a GO to notify its TO when a Blackstart Resource capabilities are compromised? 24 Hours Who is required to perform the agreed upon testing of a Blackstart Resource? The GO What minimum information should be recorded for a Blackstart Resource test? Name of Resource, unit tested, date of test, duration of test, time required to start, and any test requirements not met If requested by a TO or RC, when must Blackstart Resource test results be produced? The GO has 30 days to provide test results to its TO or RC How much time and how frequently must a GO train its personnel on starting a Blackstart Resource and energizing a bus? 2 hours every 2 years minimum What two things must be included in the GO Blackstart Resource biannual training? The system restoration plan including coordination with the TO; The procedures associated with the Blackstart Resource Agreement What must each RC have in regard to restoration? Each RC is required to have an RC Area Restoration Plan. Name the three things covered in the RC Area Restoration Plan? Blackstart Resources used to re-energize a shut down area of the BES; separation has occurred between neighboring RC; An energized island has been formed on the BES When does the RC exit the Restoration plan? All TO are interconnected its RC area is connected to all neighboring RC What 9 things are included in the RC restoration plan? High level strategy; Operating process to restore Interconnection; coordination elements between TO restoration plans; elements between RC plans; criteria and condition for reestablishing interconnections (TO-TO in the RC; TO-TO w/ other RC; w/ Other RC); Reporting requirements; Criteria for info sharing w/ neighboring RC and TO/BA in its area; RC as main contact for all parties; Criteria to transfer operations & authority back to BA Who is in control during system restoration? RC Who is given control after a system restoration has been completed? The appropriate BA To who must an RC distribute its RC Area Restoration Plan? Each of its TO, neighboring RC When must an RC distribute its RC Area Restoration Plan? Within 30 days of creation or revision of the plan How often must the RC review its restoration plan? Within 13 months from last review Who reviews an RC Restoration plan? The neighboring RC Within what time frame must a conflict in an RC plan be corrected?
