If PJM experienced an event that caused the loss of a 1,000 MW generator, which of the following would most likely provide the quickest impact to improve the undegenerating Area Control Area (ACE)?
Your system has experienced an event that caused the frequency to drop below 60.00 Hz, what would be the most likely event that occurred? - Correct Answer A generator on your system tripped offline How does the PJM dispatcher inform the Members of the PJM regulation Requirements? - Correct Answer All-Call In order for your generator to quality to supply regulation in the PJM Regulation market, it must be able to respond and attain its desired output within how many minutes? - Correct Answer 5 minutes 1 / 4
Based on a generator capability curve, in order to maximize the MVAR output of the generator, it may
be necessary to: - Correct Answer decrease the MW output of the unit
PJM maintains a regulation quality standard which states that a generator may be certified to provide regulation only after it achieves three consecutive regulation test scores of at least - Correct Answer 75% Which of the following would NOT be a cause for a sudden deviation in the balancing area ACE?
- incorrect interchange number
- loss of a tie-line RTU
- loss of internal load
- loss of adjacent control area generation - Correct Answer loss of adjacent control area generation
The primary purpose for the balancing area to have Regulation is to correct for: - Correct Answer small deviations in load It is necessary for Generation Owner dispatchers to notify PJM of unplanned unit outages: - Correct Answer as soon as practicable PJM should be made aware of any fuel shortage that a generator may experience.This information assists in analyzing the resources and reliably operating the system. A heightened
awareness is expected during: - Correct Answer extreme hot or cold conditions
Generators are required to obtain PJM approval prior to removing a generating unit from service.The only exception is for: - Correct Answer injury to personnel will be prevented Prior to removing a self-scheduled generator from service, the PJM member must first - Correct Answer give PJM the option to takeover the unit for the market 2 / 4
When PJM experiences problems with their primary digital control signal, it sometimes becomes necessary for companies with the capability, to switch to the back-up signal.
This backup signal is known as: - Correct Answer Analog control
When PJM sends cost signals to generators, to provide direction for increasing or decreasing the facility
output, this signal that is sent is known as: - Correct Answer Dispatch Rate
Under normal operating conditions, what is the limit that will provide the lowest output level of a generating unit? - Correct Answer Eco Min When PJM send out a cost signal to generators to adjust their output, the generating personnel adjust the output of the unit base on the unit's - Correct Answer price or cost curve incremental Which eSuite tool is used to maintain individual generator regulation data that is submitted by PJM members? - Correct Answer eMarket PJM's ACE configuration is such, that when the ACE is positive (+), it indicates - Correct Answer too much generation If a generator is self-scheduled, what is the minimum notification time required in order for the MW output to be adjusted? - Correct Answer 20 minutes prior to the change When corrections are made for the time error and the system scheduled frequency must be changed to implement the correction, how much is the frequency scheduled adjusted by? - Correct Answer + /- 0.02 Hz When PJM runs their Regulation test, how long do the tests normally run? - Correct Answer 40 minutes Your system has a 300 MW steam unit, but due to oil deliveries, the on-site fuel supply is diminishing. 3 / 4
What is the hourly threshold for reporting to PJM that the unit cannot operate at its maximum capacity due to the fuel limitation? - Correct Answer 72 hours What is the regulation requirement for the PJM balancing area during on-peak hours? - Correct Answer 1.0% of the forecasted peak load What is the time requirement that a generator that wishes to self-schedule itself must provide to PJM? - Correct Answer 20 minutes The PJM Peak Period Maintenance season occurs: - Correct Answer Between the 24th & 36th Wednesdays of the year Maintenance outage extensions may be granted provided that the request for an extension is made - Correct Answer Prior to the end of the outage What is the maximum time limit for the maintenance outages that occur during the PJM Peak Period Maintenance season? - Correct Answer 9 days Which of the following is NOT a control mode that PJM considers? - Correct Answer Frequency Bias What are the two NERC control standards that PJM must score at least 100% in order to be compliant? - Correct Answer DCS (Disturbance Control Standard) and CPS1 When PJM activates shared reserves with NPCC, what is the normal ramp of the MW when the event is activated? - Correct Answer 0 minutes What is the regulation required for operating the PJM balancing area during the midnight period? - Correct Answer 1.0% of the forecasted peak load What is the threshold for PJM assigning or de-assigning regulation to generators? - Correct Answer + / - 15 MW of the requirement
