ABB ret650 - Setting Guidelines

13.1.4 Setting guidelines
SEMOD54481-165 v14
The available setting parameters of the measurement function , CMMXU,
VMMXU, CMSQI, VMSQI, VNMMXU are depending on the actual hardware
(TRM) and the logic configuration made in PCM600.
The parameters for the Measurement functions , CMMXU, VMMXU, CMSQI,
VMSQI, VNMMXU are set via the local HMI or PCM600.
GlobalBaseSel: Selects the global base value group used by the function to define
IBase, UBase and SBase as applicable.
Operation: Off/On. Every function instance (, CMMXU, VMMXU, CMSQI,
VMSQI, VNMMXU) can be taken in operation (On) or out of operation (Off).
The following general settings can be set for the Measurement function ().
PowAmpFact: Amplitude factor to scale power calculations.
PowAngComp: Angle compensation for phase shift between measured I & U.
Mode: Selection of measured current and voltage. There are 9 different ways of
calculating monitored three-phase values depending on the available VT inputs
connected to the IED. See parameter group setting table.
k: Low pass filter coefficient for power measurement, U and I.
UGenZeroDb: Minimum level of voltage in % of UBase, used as indication of zero
voltage (zero point clamping). If measured value is below UGenZeroDb calculated
S, P, Q and PF will be zero.
IGenZeroDb: Minimum level of current in % of IBase, used as indication of zero
current (zero point clamping). If measured value is below IGenZeroDb calculated
S, P, Q and PF will be zero.
UAmpCompY: Amplitude compensation to calibrate voltage measurements at Y%
of Ur, where Y is equal to 5, 30 or 100.
IAmpCompY: Amplitude compensation to calibrate current measurements at Y% of
Ir, where Y is equal to 5, 30 or 100.
IAngCompY: Angle compensation to calibrate angle measurements at Y% of Ir,
where Y is equal to 5, 30 or 100.
The following general settings can be set for the Phase current measurement
(CMMXU).
IAmpCompY: Amplitude compensation to calibrate current measurements at Y% of
Ir, where Y is equal to 5, 30 or 100.
IAngCompY: Angle compensation to calibrate angle measurements at Y% of Ir,
where Y is equal to 5, 30 or 100.
