The local HMI graphical display is configured with PCM600 GraphicalDisplay Editor tool (GDE) with a measuring value which is selected to the active andreactive component as preferred. Also all Accumulated Active Forward, ActiveReverse, 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 countersfunction (PCGGIO). The output energy values are scaled with the pulse output settingvalues EAFAccPlsQty, EARAccPlsQty, ERFAccPlsQty and ERVAccPlsQty of theenergy metering function and then the pulse counter can be set-up to present the correctvalues by scaling in this function. Pulse counter values can then be presented on thelocal HMI in the same way and/or sent to the SA (Substation Automation) systemthrough communication where the total energy then is calculated by summation of theenergy pulses. This principle is good for very high values of energy as the saturation ofnumbers 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 v6The parameters are set via the local HMI or PCM600.The following settings can be done for the energy calculation and demand handlingfunction ETPMMTR:GlobalBaseSel: Selects the global base value group used by the function to defineIBase, VBase and SBase as applicable.1MRK 505 370-UUS A Section 15MeteringBusbar protection REB670 2.2 ANSI 463Application manual
