BAL-005 Flashcards
BAL-005 requires BA’s scan rate must be no more than ___ to acquire data necessary to calculate Reporting ACE.
6 seconds
BAL-005 requires the BA notify its RC within ___, starting at the initial time ACE was not able to be calculated for ___.
45 minutes
30 consecutive minutes
BAL-005 requires BA’s system used to calculate Reporting ACE be available a minimum of ___ each calendar year.
99.5%
BAL-005 requires BA’s frequency metering equipment used for calculated Reporting ACE have a minimum accuracy of ___ and be available ___ of the year.
0.001HZ
99.95%
___ and ___ were developed as ways to account for the generation and load in the appropriate BA’s ACE equation.
Dynamic Schedules
Pseudo Ties
Dynamic Schedule is a ___ update in real time and is reflected in the ___ portion of the ACE equation.
telemetered reading or value
Scheduled Net Interchange
Pseudo Tie is a ___ update in real time and used as a virtual tie line flow in the AGC/ACE equation but has no physical tie or energy metering device reflected in the ___ of the ACE equation.
telemetered reading or value
Actual Net Interchange
The ___ system will partially replace the lost generation with ___ as it increases generators on automatic control in response to negative ACE reading. ___ should bring ACE back to normal values.
AGC
Regulating Reserves
Contingency Reserves
___ generators respond very quickly to AGC.
Hydro
___ generators respond slowly to AGC.
Gas turbines and fossil fuels
Tie Line Bias Control
The BA uses the entire ACE equation including both the Interchange and the Frequency Components. NERC requires all BAs operate in this mode at all times.
Flat or Constant Frequency Control
Considers only the frequency portion of the ACE equation. Used only when area is islanded or separated from other areas.
Flat or Constant Tie Line Control
Considers only the Interchange portion of the ACE equation. Used only if frequency signal is unavailable/unreliable.
