The setting is common for all input channels on BIM, that is, if limit changes aremade for inputs not connected to the pulse counter, the setting also influencesthe inputs on the same board used for pulse counting.14.2 Function for energy calculation and demand handlingETPMMTR SEMOD153638-1 v214.2.1 IdentificationSEMOD175537-2 v4Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberFunction for energy calculation anddemand handlingETPMMTR W_Varh -14.2.2 Application SEMOD175546-4 v5Energy calculation and demand handling function (ETPMMTR) is intended for statistics of theforward and reverse active and reactive energy. It has a high accuracy basically given by themeasurements function . This function has a site calibration possibility to further increase thetotal accuracy.The function is connected to the instantaneous outputs of as shown in figure 92.ETPMMTRPQSTARTACCSTOPACCRSTACCRSTDMDACCINPRGEAFPULSEEARPULSEERFPULSEERRPULSEEAFALMEARALMERFALMERRALMEAFACCEARACCERFACCERRACCMAXPAFDMAXPARDMAXPRFDMAXPRRDIEC13000184-1-en.vsdIEC13000190 V1 EN-USFigure 92: Connection of energy calculation and demand handling function ETPMMTR tothe measurements function (CVMMXN)The energy values can be read through communication in MWh and MVArh in monitoring toolof PCM600 and/or alternatively the values can be presented on the local HMI. The local HMIgraphical display is configured with PCM600 Graphical Display Editor tool (GDE) with ameasuring value which is selected to the active and reactive component as preferred. Also allAccumulated Active Forward, Active Reverse, Reactive Forward and Reactive Reverse energyvalues 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 valuesSection 14 1MRK 504 158-UEN AMetering224Application manual
