1 Meter, Meter Reading Instrument (MRI) and Base Computer Software for Meter Data Management (MDM) Vivek Pathak Secure Meters A specifically designed programme for Da Afghanistan Breshna Sherkat (DABS) Afghanistan 11/10/2010 1

2 Technologies have evolved over a period of time and so have the meters 11/10/2010 2

3 Conventional meters Meters conventionally measured a single quantity kwh kvarh kvah Meters were used for commercial purpose, (record consumption and bill to consumer) 11/10/2010 3

4 MDI PSEB 28 11/10/2010 th January This was the meter in good old days

5 The modern meter has evolved over time Today s meter is different from yesterday s meter What is the difference? 11/10/2010 5

6 Today s meters are data loggers they churn out a lot of data They give much more than energy readings 11/10/2010 6

7 Each meter can log a lot of data Data is useful, only if it is purpose oriented 11/10/2010 7

8 Yesterday Single parameter (kwh) Single reading Manual reading Error prone Manual computation Error prone again! Multiple parameters Multiple readings (load survey) Electronic reading Less error prone Computers aid computations Less errors Today 11/10/2010 8

9 Advantages of electronic meters More accurate than electromechanical meters They are data loggers & log time stamped data They are read electronically & human errors eliminated Remote reading is possible (LPR, PSTN, GSM, GPRS) They can detect & log illogical events (tampers) Appropriate for consumer end meters only 11/10/2010 9

10 Yesterday, with electro mechanical meters Manual reading Consumption determined locally Today, with modern electronic meters Read electronically, not from display Complicated tariffs Consumption determined from computer, far away from meter Software (BCS) needed for data extraction This only extracts data from the meter 11/10/

11 Metering system software meter has a large amount of data, not practical to read using Software supplied by display, better to read meter manufacturers is Electronically not sufficient for Third party application deriving information software or services are from the data now needed We will deal with Meter Reading and system software for meter reading/ data extraction. 11/10/

12 Engineering plastic enclosure, better aesthetics LCD display with Backlight Over view of Electronic meter Calibration LED Inductively coupled PPU Rating plate Button for reverse scrolling Optical Port for electronic reading Front side sealing arrangement Button for display scrolling / scroll lock Extended terminal Block (Transparent) Terminal Block 11/10/

13 Information available in modern electronic meters 11/10/

14 Display & logged parameters Information in electronic meters can be classified as Display mode Auto display (for quick reference) Push button display (for detailed information) Scrolls automatically Displays Can be parameters accessed by for meter reader consumer viewing To see Can history be viewed data & tamper from information window when meter is Useful sealed to identify meters that need closer investigation Information is of consumer interest 11/10/

15 Display Parameters Information shown on the display of electronic meter TOU definition Self diagnostics LED Segment check Battery & NVM health RTC date & time Basic information Meter serial no. Instantaneous parameters V, I, PF, kw, kvar etc. Power On/Off hours Rising demand with elapsed time Billing information TOU wise MDs 6 or 12 history data Tamper information Missing potential Current reverse Short/Open circuit Load imbalance Date/time in RTC Cumulative Registers Cum count of events 11/10/

16 Logged Parameters 11/10/

17 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions These are electrical parameters as seen by meter at the time of reading or can be read locally using MRI Can cover Voltage, Current, PF, kw, kvar, kva etc. They are interpreted & displayed in the BCS 11/10/

18 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions These are based on tariff type programmed to meter These are packets of information on billing parameters like energy, MD etc. for each billing cycle They are also interpreted & displayed in the BCS 11/10/

19 Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions Logged Parameters They are periodic interval-wise information, intervals known as SIP SIP is typically ½ hour for consumer meters & ¼ hour for boundary meters Generally average values of kwh, kvarh, kvah, frequency, PF, Voltages, Currents, Power Down Time etc. 11/10/

20 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions They are never a conclusive proof that a No consumer meter can has be tampered called tamper proof meter These are simply illogical electrical events as seen by meter The correct way is to refer to them as events and not tampers Modern meters have 3 types of tamper related features Tamper proof features Tamper deterrent features 11/10/ Tamper evident features

21 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions They are interchange of information between meter & MRI They include change of tariff programme in meter, definition of kvarh & kvah, resetting MD, changing date/time etc. 11/10/

36 Overview Smart 2K Stands for Secure Meters Analysis & Reporting Tool. SMART 2000 is BCS (Base Computer Software) part of Integrated metering system Energy Meter BCS ( Base Computer Software) MRI ( Meter Reading Instrument) It records energy, electrical parameters, tamper and load survey data. It collects data from the meters using MRI or with modem & telephone line (RMR). These data may be used for analysis and monitoring with the help of Smart 2000 analysis and report tool. Smart 2000 works on Windows platform. Older version working on DOS was Sems Pack. 11/10/

37 Features Gives logical view of all the meter reading data according to various parameters like: Instantaneous parameter, Current energy & bill energy data, Time of day energy register data, MDs, Abnormal electrical condition data Perform various other operations called transactions on the meter like Authenticated MD reset, update Date & Time, Tariff, etc. Organized storage of meter reading data and consumer data. New user(s) with their level of access rights could be defined and / manage by supervisor based upon their usage. 11/10/

38 Features (Contd ) Exporting the meter data in the industry standard common formats (like ASCII, CSV) so data can be used by other software for billing or otherwise. Load survey information is displayed graphically whereby user has an option to see multiple parameters on the same graph or on a separate view. All the information displayed on the screen can be printed and permanent record can be maintained. Customer can choose what is to be printed. Selection on category such as Energy, Survey, Transaction, etc or on subcategory such as Main energy, Bill energy, TOD energy, history of energy registers etc. 11/10/
