Figure 86: Connection of energy calculation and demand handling function
ETPMMTR to the measurements function (CVMMXN)
The energy values can be read through communication in MWh and MVArh in
monitoring tool of PCM600 and/or alternatively the values can be presented on the
local HMI. The local HMI graphical display is configured with PCM600 Graphical
Display Editor tool (GDE) with a measuring value which is selected to the active
and reactive component as preferred. Also all Accumulated Active Forward, Active
Reverse, Reactive Forward and Reactive Reverse energy values can be presented.
Maximum demand values are presented in MWh or MVArh in the same way.
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.

Setting guidelines

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 as applicable.
Operation: Off/On
