Mw over generating - Study guides, Class notes & Summaries

Two phase conductors of a 138kV transmission line come in contact due to a storm, creating a phase to phase fault. The distance relay at each end of the line tripped and isolated the line. What two measured parameters of the line caused the distance relay to operate? Temperature and length MWs and MVARs Voltage and current Resistance and Impedance - Voltage and current What is the main cause for having low voltage on the Transmission and Distribution system? Over generation in t...

Office Area Air Conditioners C. Lighting During a Cold Weather Alert, PJM will take which of the actions - correct answer D. Assume an unavailability rate for schedule generation When PJM issues a High System Voltage Message, the GO should have its units operate at: - correct an...

NERC book quiz questions | updated 2024 You are an external BA with a frequency bais of 20 MW/.1 Hz that sees a frequency of 60.02 due to a large loss of load in the contingent BA. If your generator governor control systems responded to the frequency deviation approximately how much of a generation change would you BA experience? - -4MW Net actual interchange minus Net scheduled interchange is what? - Inadvertent interchange Suppose your interconnection operators at 59.97 Hz from one minu...

NERC SOS Pre-Assessment Questions and answers, rated A+/ VERIFIED/ What are three primary AGC control models? - Tie-Line Bias, Constant Frequency, Constant Net Interchange When a balancing Authority's ACE is zero, what is true? - The BA load-interchange-generation balancing while supporting Interconnection Frequency In a 3-phase AC generator... - Each phase is physically offset by 120 degrees Inductance is a property of an electric circuit that opposes the change in ___ - current Wha...

Accelerating Power - In a GENERATOR, the difference between the MECHANICAL INPUT POWER and the electrical output POWER (assuming no LOSSES). For a GENERATOR's TORQUE ANGLE to change, the GENERATOR must have accelerating POWER. Accumulated Inadvertent - The accumulation over time of INADVERTENT ENERGY. The accumulated inadvertent account of a BALANCING AUTHORITY represents the amount of excess ENERGY a BALANCING AUTHORITY has either supplied to the INTERCONNECTION or absorbed from the I...
