CGCM-DLR Unit Configuration
Synch Page
The Synch tab is used to configure the unit parameters that are related to the
synchronizing function of the CGCM-DLR unit.
Synchronization Limits
•
Frequency Match - Establishes the acceptance window for frequency
matching, which is 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,
which is 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,
which is 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.
•
Acceptance Delay - Establishes the time that all sync parameters must be
continuously within their respective acceptance windows to permit closing
the breaker. The Configuration table tag
SynchAcceptDly
stores this
value, expressed in seconds.
