Generator loss of field study for AEP´s Rockport plant

The computed performance of American Electric Power´s remotely located 2600 MW Rockport plant after simulated generator loss-of-field (LOF) disturbances to one of its 1300 MW cross-compound units is described. LOF conditions are reviewed, and AEP´s experience and practice in dealing with such conditions are examined. The modeling used in the computer simulation analyses is discussed. Two simulation analyses are considered: LOF on a high pressure generator with no prior disturbance and, more briefly, LOF on a reheat turbine generator with no prior disturbance. Studies of potential false operation and plans for future LOF analyses are discussed.<>
