C) dynamic and spinning
D) spinning and primary - ✔✔C) dynamic and spinning
During a system restoration you have 400MW of Steam capacity, 350MW of CT
capacity and 300MW of Hydro capacity restored. Your largest contingency is a
200MW Steam Unit. You have also restored 150MW of under-frequency load.
What is your total dynamic reserve? (Load pick-up factors are 5% for steam, 15%
for hydro and 25% for CT)
,A) 142.5MW
B) 152.5MW
C) 285MW
D) 292.5MW - ✔✔C) 285MW
What is the most critical communication path when restoring large load
blocks early in a system restoration?
A) Between the Generating Unit and the Transmission Owner
B) Between PJM and the generating plant
C) Between the Generator Owner (or MOC) and the generating unit
D) Between the transmission owner and the MOC - ✔✔A) Between
the Generating Unit and the Transmission Owner
Your entire system has blacked out due to an event. You receive word from PJM
that the entire region is affected as well. Your blackstart generation resources are
, spread throughout your system, which cover a large area. Which
restoration strategy would be the best for you to implement?
A) Combination approach
B) Bottom-up Core Island approach
C) Top-down approach
D) Bottom-up Multiple Island approach - ✔✔D) Bottom-up multiple
island approach
During a system restoration, which entity directs the loading of generation, to
match the load restored?
A) PJM
