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.
EOP-010-1 describes the combined effects of a GMD event: transformer hot-spot heating, lost Reactive Power sources, higher Reactive Power demand and Protection System Misoperation. What end result does the standard say the combination may produce?
- A. Voltage collapse and blackout
- B. Sustained overfrequency
- C. Widespread frequency decay
- D. Loss of the interchange schedule
Show the answer
Answer A Voltage collapse and blackout
The background section of the standard ends that chain with voltage collapse and blackout, which is why the mitigating activities in a GMD Operating Plan center on holding voltage up and keeping reactive reserve available. A GMD does not act on frequency the way a generation-to-load imbalance does.
Reference: EOP-010-1 Background
EOP-010-1 lets a Transmission Operator meet R3 with either a GMD Operating Procedure or a GMD Operating Process. What distinguishes the Operating Process?
- A. It gives ordered steps assigned to named operating positions
- B. It gives general steps with options chosen for Real-time conditions
- C. It gives the Reliability Coordinator authority over each step
- D. It gives the document a yearly review cycle rather than a monthly one
Show the answer
Answer B It gives general steps with options chosen for Real-time conditions
The glossary describes an Operating Process as general steps toward a generic goal, with options selected according to Real-time conditions, while an Operating Procedure is the ordered, position-specific document. Either form satisfies R3 as long as it contains the three required elements.
