• Internal tracking – GenRatedExcI
• Traverse rates – GenRated_V, GenRated_I, GenRatedExcI
Synch Tab
The Synch tab is used to configure the unit’s parameters related to the
synchronizing function of the CGCM unit.
Synchronization Limits
• Frequency Match - Establishes the acceptance window for frequency
matching, defined by Configuration table tags SyncFreqLoLimit and
SyncFreqHiLimit. These tags are set by using the Lower Limit and Upper
Limit fields in the Synch tab and are expressed in Hertz.
• Voltage Match - Establishes the acceptance window for voltage matching,
defined by Configuration table tags SyncV_LoLimit and
SyncV_HiLimit. These tags are set by using the Lower Limit and Upper
Limit fields in the Synch tab and are expressed in percent of rated
generator voltage.
• Phase Match - Establishes the acceptance window for phase matching,
defined by Configuration table tags SyncPhLoLimit and
SyncPhHiLimit. These tags are set by using the Lower Limit and Upper
Limit fields in the Synch tab and are expressed in degrees.
