Protection and Logic Functions
Group Settings (SET Command)
Set FSYNCST and VSYNCST to individually initiate automatic frequency
and voltage matching, respectively. For example, FSYNCST := IN301
activates frequency matching when IN301 momentarily asserts. You can also
use the ASCII command AST to activate both frequency and voltage
matching simultaneously. Use the ASCII command ASP to stop the
autosynchronizer function; see AST Command (Start Autosynchronizer) and
ASP Command (Stop Autosynchronizer) in Section 7: Communications. Relay
Word bits FSYNCACT and VSYNCACT indicate that frequency and voltage
matching logic, respectively, are active. Set the maximum active time allowed
for the frequency and the voltage matching logic by setting FSYNCT and
VSYNCT as necessary. The frequency, phase angle, and voltage matching
features are described in the following text.
Frequency Matching
Refer to Figure 4.116 for the functional block diagram of the frequency
matching function.
