Answer each one before you open the explanation. On the exam there's no explanation, and you have about 77 seconds a question on RC and BT, 90 on TO and BI.
Real-time monitoring shows a Facility loaded above its applicable rating inside a Transmission Operator Area. Under TOP-001-6, what is the Transmission Operator required to do?
- A. Wait for the Reliability Coordinator to issue an Operating Instruction
- B. Request a revised Facility Rating from the equipment owner
- C. Initiate its Operating Plan to mitigate the SOL exceedance
- D. Shed firm load until the Facility is back within its Normal Rating
Show the answer
Answer C Initiate its Operating Plan to mitigate the SOL exceedance
Requirement R14 obliges the Transmission Operator to initiate its Operating Plan to mitigate a SOL exceedance identified through Real-time monitoring or a Real-time Assessment. Waiting for direction is not an option, and load shedding comes only after other System adjustments have been exhausted.
Reference: TOP-001-6 R14
A Transmission Operator's own study gives a 725 MW limit for a path, while its Reliability Coordinator's established limit for the same path is 685 MW. How should the Transmission Operator operate the path?
- A. To 725 MW, the value produced by the Transmission Operator's study
- B. To 705 MW, the average of the two established values
- C. To 725 MW, pending confirmation from the Reliability Coordinator
- D. To 685 MW, the more limiting of the two established values
Show the answer
Answer D To 685 MW, the more limiting of the two established values
TOP-001-6 Requirement R18 directs the Transmission Operator to operate to the most limiting parameter where there is a difference in SOLs, which here is 685 MW. Averaging the two numbers gives 705 MW and has no basis in the standard, and operating to the looser value while waiting for confirmation leaves the System above the governing limit.
