Internally provided LM Command Variables
ID
LMCV
Function
04.68 ATS start request 11983 If this variable is true, LDSS PL
wants to start the engines. This
command variable is incorporated
in the LM “Start request in AUTO”.
04.69 Inhibit ATS 11984 This variable is true if “04.68 ATS
start request” is true and the
rated power on the bus bar is
lower than the predicted load (+
active reserve power ). It is
usually passed internally to
release the GGB or external to
release the ATS control.
86.36 LM: LDSS predicted 12606 Result of the LM LDSS with load
prediction.
6.3.16 Derating And Uprating Of Power (Details)
6.3.16.1 Direct Derating
General notes
The idea of direct derating of power is that the user can control with an analog value,
usually from outside, the amount of reduction. For this purposes mainly an analog input
would be taken. Additionally in some applications are uprating desired, for example
during load sharing procedures, which can be as well executed in determined
circumstances.
Derating
If parameter 15149 "Direct Derating" ( ╚═▷ 15149 ) is enabled, the output value of the
AnalogManager 15147 "AM Derating source" determines the derating directly. This
derating value is also provided as AnalogManager variable under "81.21 AM Derating
source". For derating the active power setpoint, the value shall vary between 100% (no
derating) and 0% (full derating). The derating function parameters 15143, 15144, 15145
are not in use.
Uprating
If parameter 15149 "Direct Derating" (ID ╚═▷ 15149 ) is enabled, the output value of the
AnalogManager 15147 "AM Derating source" determines the uprating directly. This value
is also provided as AnalogManager variable under "81.21 AM Derating source". For
uprating the value shall vary between 100% (no uprating) and higher (uprating begins).
The scaling with parameters 15143, 15144, 15145 is not in use.
Combined Derating and Uprating
If parameter 15149 "Direct Derating" (ID ╚═▷ 15149 ) is enabled, the output value of the
AnalogManager 15147 "AM Derating source" determines the derating/uprating directly.
This value is also provided as AnalogManager variable under "81.21 AM Derating source".
