COMPARISON OF KVA DEMAND - SLIDING .pptx

Comparison of KVA demand recorded in meters

1. COMPARISON OF MAXIMUM DEMANDS [SLIDING (30M/10) AGAINST BLOCK (15M)] By Mrs. Madhuri Kulkarni, AEE, TQA Laboratory & Team RPTD, Pune.

2. EXERCISE DETAILS AN EXERCISE WAS CONDUCTED FOR 7 NO. OF HT CONSUMERS UNDER RASTA PETH URBAN CIRCLE (RPUC), PUNE. THE CONSUMERS SELECTED ARE FROM DIFFERENT CATEGORIES HAVING DIFFERENT TYPES OF LOADS/ACTIVITIES. AN HT TOD METER WAS INSTALLED IN SERIES WITH THE BILLING METER OF THE CONSUMER & THE DATA WAS MONITORED FOR A PERIOD OF 8 TO 20 DAYS. THE ‘BILLING DATA’ & THE ‘LOAD SURVEY DATA’ OF BOTH THE METERS WAS ANALYSED FOR ‘KVAMD’ COMPARISON PURPOSE. 2

3. EXERCISE PREPARATION IT WAS NOT POSSIBLE TO PROGRAM THE EXISTING ‘ KVAh COMPATIBLE’ METERS WITHOUT THE HELP OF METER MANUFACTURERS. HENCE, FROM THE REPLACED METERS STOCK, THE FOLLOWING TYPE OF METERS WERE USED FOR THE EXERCISE : A. ‘0317’ SERIES L&T MAKE METERS. B. ‘ELSTER’ MAKE A-1800 TYPE METERS WITH ‘15 MIN. BLOCK WINDOW’ DEMAND INTEGRATION. C. ‘ELSTER’ MAKE A-1800 TYPE METERS WITH ‘15 MIN. SLIDING WINDOW’ DEMAND INTEGRATION (DEMAND RECORDED IN RESPECTIVE INTEGRATION PERIOD IN ‘LOAD SURVEY DATA’ IS USED FOR COMPARISON) . THE METERS INSTALLED IN SERIES WITH BILLING METERS WERE PREPARED/PRE-PROGRAMMED AS EXPLAINED IN NEXT SLIDE. 3

14. 14 SOME SAMPLE PLOTS OF KVAMD OF BILLING & SERIES METER

15. CONCLUDED THAT.. BILLING DATA THE COMPARISON OF ‘BILLING DATA’ OF BOTH THE METERS INDICATES THAT THE KVA DEMAND RECORDED BY THE METER WITH ‘15 MINUTES BLOCK WINDOW’ INTEGRATION IS MORE THAN THE KVA DEMAND RECORDED BY THE METER WITH ‘30 MINUTES BLOCK WITH 10 MIN. SLIDING WINDOW’ INTEGRATION. LOAD SURVEY DATA THE PLOT/COMPARISON OF KVA DEMAND IN ‘LOAD SURVEY DATA’ OF BOTH THE METERS INDICATES THAT THE KVA DEMAND RECORDED BY THE METER WITH ‘15 MINUTES BLOCK WINDOW’ INTEGRATION IS ALWAYS GREATER THAN THE KVA DEMAND RECORDED BY THE METER WITH ‘30 MINUTES BLOCK WITH 10 MIN. SLIDING WINDOW’ INTEGRATION. 15
