ABB REB670 Series - Setting guidelines

Alternatively, the energy values can be presented with use of the pulse counters function
(PCGGIO). The output energy values are scaled with the pulse output setting values
EAFAccPlsQty , EARAccPlsQty , ERFAccPlsQty and ERVAccPlsQty of the energy metering
function and then the pulse counter can be set-up to present the correct values by scaling in
this function. Pulse counter values can then be presented on the local HMI in the same way
and/or sent to the SA (Substation Automation) system through communication where the
total energy then is calculated by summation of the energy pulses. This principle is good for
very high values of energy as the saturation of numbers else will limit energy integration to
about one year with 50 kV and 3000 A. After that the accumulation will start on zero again.
15.2.3 Setting guidelines
SEMOD175556-4 v6
The parameters are set via the local HMI or PCM600.
The following settings can be done for the energy calculation and demand handling function
ETPMMTR:
GlobalBaseSel : Selects the global base value group used by the function to define IBase , UBase
and SBase . Note that this function will only use IBase value.
Operation : Off / On
EnaAcc
: Off / On is used to switch the accumulation of energy on and off.
tEnergy : Time interval when energy is measured.
tEnergyOnPls : gives the pulse length ON time of the pulse. It should be at least 100 ms when
connected to the Pulse counter function block. Typical value can be 100 ms.
tEnergyOffPls : gives the OFF time between pulses. Typical value can be 100 ms.
EAFAccPlsQty and EARAccPlsQty : gives the MWh value in each pulse. It should be selected
together with the setting of the Pulse counter (PCGGIO) settings to give the correct total pulse
value.
ERFAccPlsQty and ERVAccPlsQty : gives the MVArh value in each pulse. It should be selected
together with the setting of the Pulse counter (PCGGIO) settings to give the correct total pulse
value.
For the advanced user there are a number of settings for direction, zero clamping, max limit,
and so on. Normally, the default values are suitable for these parameters.
