NERC book quiz with correct answers graded A+

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? - Answer -4MW Net actual interchange minus Net scheduled interchange is what? - Answer Inadvertent interchange Suppose your interconnection operators at 59.97 Hz from one minute after midnight to noon and operate at 60.05 Hz from 12:01 to midnight. What should you do if a time error correction was implemented just after midnight to correct for the timer error accumulated during this 24 hour period? - Answer Change frequency schedule to 59.98 Hz If BA ABC's RT signal for power flow over ABC's midway tie-line with BA XYZ is significantly in error, the ABC system operator shall - Answer Adjust the control setting (e.g. substitute a value for the tie line power flow in the EMS) to compensate for the equipment error until repairs can be made The normal and recommended mode of AGC is what? - Answer Tie line frequency bias A 100 MW generator at 50 MW output has a 5% governor droop response will respond to how much of a -.15Hz frequency deviation (actual frequency 59.85 Hz) - Answer +5 MW
