CHAPTER 6: METERING POWER889 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL 6–15PowerThe following figure illustrates the convention used for measuring power and energy in the8 Series devices.NOTENOTE:Power 1 is calculated using 3-phase J1 Currents & 3-phase J2 Voltages. Power 2 iscalculated using 3-phase K1 Currents & 3-phase J2 Voltages.Figure 6-4: Flow direction of signed values for watts and VARsPath: Metering > Power 1(X)Real Total (Real)Range: - 214748364.8 kW to 214748364.7 kWPER IEEE CONVENTIONSParameters as seen bythe 8-series relaysVoltageGeneratorGeneratorInductiveInductive ResistiveResistiveGeneratorGenerator8-SERIES IEDGGMMGGVCGICVAGIAVBGIBVCGICVAGIAVBGIBVCGICVAGIAVBGIBVCGICVAGIAVBGIB+Q+Q+Q+QPF = LeadPF = LeadPF = LeadPF = LeadPF = LagPF = LagPF = LagPF = LagPF = LagPF = LagPF = LagPF = LagPF = LeadPF = LeadPF = LeadPF = Lead–Q–Q–Q–Q–P–P–P–P+P+P+P+PIAIAIAIAS=VILOADLOADResistiveResistiveLOADLOADWatts = PositiveVars = PositivePF = LagCurrent–Θ °1Voltage8-SERIES IEDWatts = PositiveVars = NegativePF = LagCurrent–Θ °2S=VI–Θ °3Voltage8-SERIES IEDWatts = PositiveVars = NegativePF = LagCurrentS=VIVoltage8-SERIES IEDWatts = PositiveVars = NegativePF = LagCurrent–Θ °4S=VI894160A1.CDR
