An Investigation of Techniques to Expedite Synchronizing for Pump-Storage Units and Standby Generating Units,

摘要

The rapid startup potential of hydro and pumped-storage power is placed at a premium by the increasing preponderance of thermal power sources which inherently have rather sluggish response. To better exploit the rapid startup potential,the latitudes and constraints of synchronizing are examined and means are developed to expedite the synchronizing process. A special synchronizer is developed with compensation for acceleration and with sensitivity to residual voltage. By this means,transients of induction synchronizing are reduced,pull-in torque may be increased,and full voltage synchronizing may be achieved at higher acceleration and in less time for start up of emergency standby units.
