PJM Test Questions And Answers With Verified Study Solutions

PJM Test Questions And Answers With Verified Study Solutions Which of the following balancing control modes is used by PJM under normal operations? Tie-Line Bias Which of the following influences does PJM consider when performing their system load forecast? Weather Conditions & Day of the Week All of the following are limits that must be submitted to PJM for generating units EXCEPT: 1. Eco Min 2. Eco Max 3. Emergency Max 4. Dynamic Instability Dynamic Instability 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)? 1. Remedial Action Reserve 2. Synch Reserve 3. Non -Synch Reserve 4. Secondary Reserve Synch Reserve 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? A generator on your system tripped offline How does the PJM dispatcher inform the Members of the PJM regulation Requirements? 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? 5 minutes Based on a generator capability curve, in order to maximize the MVAR output of the generator, it may be necessary to: 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 75% Which of the following would NOT be a cause for a sudden deviation in the balancing area ACE? 1. incorrect interchange number 2. loss of a tie -line RTU 3. loss of internal load 4. loss of adjacent control area generation loss of adjacent control area generation The primary purpose for the balancing area to have Regulation is to correct for: small deviations in load It is necessary for Generation Owner dispatchers to notify PJM of unplanned unit outages: 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: 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: injury to personnel will be prevented Prior to removing a self -scheduled generator from service, the PJM member must first give PJM the option to takeover the unit for the market 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: 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: Dispatch Rate Under normal operating conditions, what is the limit that will provide the lowest output level of a generating unit? 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 price or cost curve incremental Which eSuite tool is used to maintain individual generator regulation data that is submitted by PJM members? eMarket PJM's ACE configuration is such, that when the ACE is positive (+), it indicates 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? 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? + /- 0.02 Hz When PJM runs their Regulation test, how long do the tests normally run? 40 minutes Your system has a 300 MW steam unit, but due to oil deliveries, the on -site fuel supply is diminishing. What is the hourly threshold for reporting to PJM that the unit cannot operate at its maximum capacity due to the fuel limitation? 72 hours What is the regulation requirement for the PJM balancing area during on -peak hours? 1.0% of the forecasted peak load
