The local HMI graphical display is configured with PCM600 GraphicalDisplay Editor tool (GDE) with a measuring value which is selected to the activeand reactive 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 outputsetting values EAFAccPlsQty, EARAccPlsQty, ERFAccPlsQty and ERVAccPlsQtyof the energy metering function and then the pulse counter can be set-up to presentthe correct values by scaling in this function. Pulse counter values can then bepresented on the local HMI in the same way and/or sent to the SA (SubstationAutomation) system through communication where the total energy then iscalculated by summation of the energy pulses. This principle is good for very highvalues of energy as the saturation of numbers else will limit energy integration toabout one year with 50 kV and 3000 A. After that the accumulation will start onzero again.11.2.3 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, UBase and SBase as applicable.Operation: Off/On1MRK 511 423-UEN A Section 11MeteringBay control REC650 2.2 IEC 227Application manual
