Tie line frequency bias - Study guides, Class notes & Summaries

NERC Class with Complete Solution Rated A+ Frequency Bias and Jointly Owned Units (JOU) -Answer BAs that use dynamic schedule or pseudo-ties for a jointly owned unit share responsibility for it in their bias settings. Fixed schedules for JOU require host BA to include total response for them in their bias setting. Frequency Bias and BA frequency response -Answer BAs must maintain a frequency bias that is equal to or greater than the BA frequency response. If the frequency bias is less th...

EPRI Chapter Test Questions with Verified Solutions If a generator is producing 500MW and 200Mvar, the generator is: Lagging 87 Is the IEEE device number for a differential relay. Can a Synchronous machine have a negative torque angle? What doies this mean? Yes, the machine is absorbing active power. A customer load is fed at 12o Volts. The customer's voltage is doubled while the load magnitude stays the same. What effect does this have on the power losses? Decreases the losses by a factor o...

The Reliability Coordinator just informed you of a slow time error correction which will begin at the top of the next hour. Your EMS system will not let you change your scheduled frequency. Your Frequency Bias Setting is -100 MW/.1Hz. What action should you take? A) Increase Net Interchange Schedule by 20 MWs. B) Inform the Reliability Coordinator that you cannot participate in the time error correction. C) Decrease Net Interchange Schedule by 20 MWs. D) Increase Net Interchange Sche...

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 minute after midnight to noon and operate a...
