Breaker Delay allows the PSM module to compensate for the
delay from CloseRelayOK (%I offset 7) being asserted until the
synchronizing breaker contacts actually make electrical
contact.
Set to 0 to use static phase angle synchronization Set to actual
closure delay for rotating phase angle synchronization. Enter
the ACC200 turn-on time plus the published closing delay, or
measured closing delay from
energizing the breaker, until the contacts are closed.
Note: When the ANSI 25 Breaker Delay parameter is set
to a non-zero value, the phase angle difference at
which RelayCloseOK is set and the IC694ACC200
relay outputs close varies in direct proportion to
the rate of change of the phase angle of Grid 2
relative to Grid 1. Higher rates of phase angle
change and larger breaker delays require that the
PSM assert RelayCloseOK earlier to ensure that the
breaker contacts close within the safe region set
by the ANSI 25 Phase Shift Threshold parameter.
Range: 0 to 1000
Default: 0 (implies static phase angle synchronization)
The maximum difference between the Grid 2 RMS voltage and
the Grid 1 RMS voltage, as a percentage of Grid 1, where the
grids may be connected. Grid 1 is assumed to be a stable utility
grid. Grid 2 is assumed to be a variable generator grid. This
value is a tolerance around the Grid 1 voltage.
Range: 1 to 100
Default: 10
The maximum difference between the Grid 2 frequency and
the Grid 1 frequency, in Hz, where the grids may be connected.
Grid 1 is assumed to be a stable utility grid. Grid
2 is assumed to be a variable generator grid. This value is a
tolerance around the Grid 1 frequency.
Range: 0.01 to 5.00
Default: 0.1
The voltage below which the Under-Voltage Alarm status is set
(after the Under-Voltage Delay), as a percentage of the
Nominal Voltage parameter.
Range: 0 to 99
Default: 90
