PJM Generation Dispatcher Exam Practice Questions and Solutions, Exams of Electrical Engineering

Virginia State University (VSU)Electrical Engineering

A set of practice questions and solutions related to the pjm (pennsylvania-new jersey-maryland) generation dispatcher exam. It covers key concepts such as voltage regulation, generator limits, synchronization procedures, geomagnetic disturbance protocols, terrorism advisory alerts, and emergency procedures. The questions address real-time operating scenarios, reactive power management, outage management, and restoration processes. It is useful for those preparing for the pjm generation dispatcher exam, offering insights into the operational aspects of power grid management and regulatory compliance. It also covers topics such as voltage/reactive power schedule, operating reserves, and frequency control.

PJM Generation Dispatcher Exam Practice

Solutions

1.An EXCITER on a traditional generator does what?: Voltage regulation (AVR) if you change the

excitation current, you change the voltage.

2.ECO Min, ECO Max, and EMERG Max are generator .: -

Limits

3.When synchronizing to the interconnection, what needs to be synchro- nized?: Frequency,

Voltage, and phase angle.

4.GMD (GeoMagnetic Disturbance) procedure is implemented when?: 10A or greater is

measured by special equipment at Missouri Ave or Meadowbrook and the measurement is

confirmed by one of the following other sources: Excess

transformer current @ Meadowbrook, Beddington, Donbs, or Black Oak, high MVAR requirements

on transformers @ Hopw Creek or Salem nuclear subs, or high DC measurements @ Limerick or

Peach Bottom.

5.What are the 2 types of National Terrorism Advisory Alerts?: Elevated and Imminent.

6.What action does PJM take for a terrorist attack, fuel delivery emergency, or GMD's?:

Conservative Operations

7.What does PJM put the most emphasis on during a terrorist/sabotage event?: Operations

and Communications

8.What does PJM request during a low voltage alert?: RRC - reactive reserve check

9.PJM issues a Heavy Load Voltage Warning how many hours prior to imple- mentation?: 4 hours

10.What should generation owners/operators do during a High System Volt- age Action?: Operate

at the lower bandwidth of the voltage schedule.

11.How many hours do you have to report a 24-hr reportable NERC distur- bance?: 6 hours

12.What report is generated during a Max Emergency Gen Alert?: SSR - Supplementary

Status Report

13.What part of the SSR is the Fuel Limited Resources accounted for?: Part G Resource Limited

Units which are units that are not able to run at max capacity for more than 72 hours.

14.What kind of Emergency Procedures occur during real time operating hours?: Actions

15.What is the per Unit (p.u.) for a 345 kV nominal voltage that is currently at 348 kV?: 348/345 =

1.008 pu

16.What is the Emergency Reducible Generation (ERG) if the Eco Min is 100 and the Emergency

Min is 75?: Eco Min - Emerg Min = 25MW

17.How many Black Start units are required for critical load/TO zone?: 2 Black Start units

18.What is the minimum amount of hours for fuel supply for Black Start units?: 10 hours,

must notify PJM when it reaches that level.

19.Regulation must be attainable within how many minutes?: 5

20.ACE - Area Control Error is used to balance what 2 things?: Generation and Load

21.If your ACE in your control area is -1500, what would you do?: 100% spinning

(synchronized) reserves

22.Synchronized reserves is generation output from a synchronized resource that can be increased

w/in 10 min or?: Reduction in load from a synchronized resource w/in 10 min.

4 /

37.Operating reserves consists of what?: Synchronized reserves, non-synchro- nized reserves

(quick start), and supplemental reserves (secondary)

38.Regulating units (demand response resources) provide a variable amount of generation under

automatic control to provide what?: Correction for small deviations in load.

5 /

39.Where's the ideal point for regulation to operate?: Midpoint

40.What type of outage may be deferred to beyond the next weekend or can be postponed to the

following Mon morning at 0800?: Maintenance outage

41. How long is a maintenance outage during PPM- Peak Period Maintenance?-

: 9 days

42.How long is a maintenance outage during non-Peak Period Maintenance?-

: Unlimited

43.When ambient temperatures are low, what happens to CT operation?: MW increased as

temperature decreases.
