Default
Description
Factor
coefficient in the whole reactive power
adjustment coefficient.
35
Dead Bus Voltage
(10-50)V
30
It is considered bus no power when bus voltage is
lower than dead Bus voltage.
36
Sync Voltage
Difference
(0-30)V
3
It is considered voltage synchronization when the
voltage difference between generator and bus is
lower than synchronization voltage difference.
37
Sync Positive
Frequency
Difference
(0-2.0)Hz
0.2
It is considered frequency synchronization when
the frequency difference between generator and
bus is less than “Sync Voltage Difference” but
more than “Sync Negative Frequency Difference”.
38
Sync Negative
Frequency
Difference
(0-2.0)Hz
0.1
39
Sync Phase
Difference
(0-20)°
10
It is considered phase angle synchronization
when the initial phase difference between
generator and bus is lower than “Sync Phase
Angle Difference”.
40
Fail to Sync Delay
(5.0-300.0)s
60.0
When there is no sync signal been detected
during “Fail to Sync Delay”, corresponding alarm
will be initiated based on the “Fail to Sync Action”.
41
Fail to Sync Action
(0-5)
1
0: Block; 1: Warn; 2: Trip; 3: Shutdown; 4: Safety
Trip; 5: Safety Stop.
42
Current Busbar
Gensets
(0-0xFFFF)
0xFFFF
16-bit data; each bit represents a genset; 0
represents gensets are not on this busbar; 1
represents gensets are on this busbar; bit0
represents the gensets with 0 ID; bit15 represents
the gensets with 15 ID.
43
Current Shaft of
Busbar
(0-0x000F)
0x000F
Each number represents a unit, 0 represents SG
unit but not in this busbar, 1 represents SG unit in
this bus, bit0 represents the unit with ID 0, bit3
represents SG unit with ID 3.
44
Shutdown
Percentage Rest
(0-1)
0
When it is enabled, the Min. Load Percentage=
Current Power (Total Power- Power of Unit to
Stop); When it is disabled, the Min. Load
Percentage= Current Power/Total Power.
