EPRI Terms & Definitions Exam Questions & Answers 2023/2024 OFF-PEAK - ANSWER-Those hours or other PERIODs defined by NAESB business practices, contract, AGREEMENTs, or guides as PERIODs of lower electrical DEMAND. OHM'S LAW - ANSWER-A basic electrical law that relates the VOLTAGE (V), CURRENT (I), and IMPEDANCE (Z). Ohm's law is commonly stated as:V = I × Z ON-PEAK - ANSWER-Those hours or other PERIODs defined by NAESB business practices, contract, AGREEMENTs, or guides as PERIODs...

You are an external BA with a frequency bais of 20 MW/.1 Hz that sees a frequency of 60.02 due to a large loss of load in the contingent BA. If your generator governor control systems responded to the frequency deviation approximately how much of a generation change would you BA experience? -4MW Net actual interchange minus Net scheduled interchange is what? Inadvertent interchange Suppose your interconnection operators at 59.97 Hz from one minute after midnight to noon and operate a...

What is the purpose in accounting for Inadvertent Interchange among the Balancing Authorities? To ensure that Balancing Authorities do not excessively depend on other Balancing Authority Areas for meeting their demand or Interchange obligations. In your Interconnection, a generator tripped that was large enough to reduce the frequency from 60.00 Hz to 59.94 Hz. Your Balancing Authority's Frequency Bias is 200 MW/0.1 Hz. How many MW would your system initially contribute to frequency sup...

What entity balances generation and monitors/employs contingency reserves? - Balancing Authority (BA) What entity has the widest system view and is the "supervisor"? - Reliability coordinator (RC) What entity monitors transmission lines and operates tap-changers, breakers, capacitors, etc? - Transmission Operators (TOP) What is a group of BAs that have agreements to help cover each other's reserve and regulation requirements? - Reserve Sharing Group (RSG) What entity s...

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 bi as 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 control...
