NERC Test Questions with 100% Verified Solutions( Rated 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 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? - They will manage, alarm, test and/or actively monitor, especially emergency comm facilities and equipment (non-routine equipment) When can languages other than English be used? - Only for internal operation, Operation of the BES requires comms in English 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? - Ensure BA, TO, GO, and RC have comms and capability to use them for addressing emergency and that operators are trained to use them Who should a BA or TO notify if they are aware of any condition that could threaten area reliability or when shedding load? - Notify their RC and any other potentially affected BA or TO 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
