6F2T0207 (0.01)GRE200 (5,6)- 786 -Statistics data (Peak-demand value group)Similar to the demand feature (Demand value group), the user can have another peak-demandfeature that provides the Max/Min/Ave data that can be obtained from the initialized time tothe current time; note these data have been calculated from the first energizing moment of theIED. That is, the data of the peak-demand feature gets to have the latest values in every cycle;the data will be replaced if the past data is not needed. The user can find that the nature ofthe collected values in the peak-demand values being identical to the one of the Demand valuegroup.9.5.1 Max/Min/Averaged information about the peak-demand feature(i) Maximum valueThe peak-demand feature starts to collect the data in every cycle after the IED energized; thepeak-demand feature will have the largest data. If the present data is larger than the past onewith the peak-demand feature will replace the past one for the present one. The maximumvalue will be cleared when the data is reset.(ii) Minimum valueSimilarly, for the minimum value, the IED displays the smallest data after energizing; the datawill be replaced when the present data is smaller than the past one.(iii) Averaged valueThe averaged value is computed using the data in the IED memory, the data which wascollected after energizing. Collecting data stays on for a long time; hence, when the counterwith regard to the data collection gets to be 2,147,483,647(=0x7FFFFFFF; almost 68 years),resetting data is performed.9.5.2 Resetting data of peak-demand featuresThe data will be cleared by the following operations:(a) To energize the IED or to make the initialization about the IED functions(b) To operate “Reset All Values” on the IED menuFigure 9.5-1 Reset menu for Peak demand valuesPeak Demand10:48 1/2Peak Demand Value >Reset All Values +
