System studies identify what - ANSWER-Predict operations and identify constraints If ACE remains the same and frequency goes up what has happened? - ANSWER-Someone lost load When a generator has its AVR in service it is a? - ANSWER-Dynamic source of reactive power Black start resource testing is done every? - ANSWER-3 years Each BA shall operate its AGC on? - ANSWER-Tie line Frequency Bias When is voltage reduction reportable? - ANSWER-Greater than 3% Reactors do what? - ANSWER-Absorb VARs What AGC mode should a generator use when islanded? - ANSWER-Flat Frequency Implement back up functionality plan within? - ANSWER-2 hours Who submits the request for interchange for an emergency transaction? - ANSWER-The sink BA Transmission lines that are heavily loaded do what? - ANSWER-Absorb VARs Undervoltage load shedding is designed to? - ANSWER-Reduce power flow into an area A generator will increase output when? - ANSWER-Frequency decreases EEA 3 - ANSWER-Anticipating or implementing firm load interruption What is the relation to frequency and load when islanded? - ANSWER-To increase frequency 1 Hz you must shed 6-10% of load Zone 2 - ANSWER-120-150% of the line. Backup for Zone 1. What resource should be used during high load periods? - ANSWER-Capacitive Who do you notify about curtailed interchange? - ANSWER-All BA's on scheduled path. If providing overlap modify your? - ANSWER-Frequency Bias setting When do you reduce power flows and increase generation? - ANSWER-During low voltage EEA 2 - ANSWER-Excluding shedding firm load In what part of the ACE equation is dynamic schedules accounted for? - ANSWER-NIs Zone 3 - ANSWER-130-300% of a line What is reduced when power lines are connected in parallel? - ANSWER-Impedance If frequency and ACE goes down what has happened? - ANSWER-You lost load What do capacitors do? - ANSWER-Increase VARs Primary cause of low voltage - ANSWER-VAR losses Contingency analysis tools use - ANSWER-LODF line outage distribution factors When frequency drops -> generation increases. What is this called - ANSWER-Governor response What relay protects generators and transformers from prolonged Hv? - ANSWER-Over voltage relay When do generators produce VARs - ANSWER-Over excited (lagging) When a generator is over excited it is said to be what - ANSWER-Lagging When a generator is under excited it is said to be what - ANSWER-Leading What is the relationship of a reactor and a lines impedance - ANSWER-Adding a reactor increase impedance What kind of power do you have with induction - ANSWER-Reactive Who monitors SOLs - ANSWER-TOP and RC A line that is lightly loaded is an example of what kind of load - ANSWER-Capacitive lod Establish contingency reserve restoration period - ANSWER-90 mins
