TOU energy measurement (six tariffs, 4 quadrants)Measure total and the energy by 6 tariffs for import/export kWh, kvarh as well as the kvarh of 4 quadrants, the def

23、ination of 4 quadrants is described in diagram 3.Diagram 3: Defination of 4 QuadrantsThere are two types of reactive measurement mode as following: 1) Import Reactive= Quadrant + QuadrantExport Reactive= Quadrant + Quadrant2) Import Reactive= Quadrant + QuadrantExport Reactive= Quadrant + QuadrantTh

24、ese two types of measurement mode can be programed before usage.The accuracy calss for reactive measurement is 0.2S and calss 1.0 for reactive, the reactive accuracy is inspected by follow the standard Class 1 and 2 Static AC Active Energy Meter Year section (Maximum 14 times): The one year can be d

25、evided into several time section which can be applied with different schedule (Maximum 12 times) of day switch times (Maximum 14 times), the tariff for each day switch can be programmed but the maximum number is 6 tariffs. There are special time in a year which can be programmed like the weekend and

26、 holiday, customer may set special day switch schedule for these days. Current tariff can be displayed and reviewed on the left buttom of LCD. 3.2. Measure current, voltage, frequency and power Meter can measure voltage & current of each phase and each element, measure total and reach pahse & elemen

27、t kW, kvar, power factor and frequency. The voltage between the virtual center and line for a 3 phase 3 wire meter can be calculated. The distinguish ability for voltage 0.01V, for current is 0.001A, for kW and kvar is 0.0001, for frequency is 0.001Hz. The power direction can be indicated by displyi

28、ng the symble “P”, “+”, “-”, “Q” and “14”. 3.3. Calculate M.DMeter can measure total M.D. of import/export kW & kvar, 4 quadrant kvar with time, and the M.D. can be measured by each tariffs also. The demand interval is programable from 5, 10, 15, 30 and 60 minutes, sliding time is programable from 1

29、, 2, 3 and 5 minutes. 3.4. Harmonic analyzeDSP convert the voltage and current signal by FFT in 256 points, then the value, phase of 239 times harmonic voltage and current can be calculated out, the accuracy for harmonic value is 2% (for 221 times harmonic), the phase accuracy is +12 degree. All har
