1 1 ABT Based Boundary Metering

2 2 ABTBoundary Metering+

3 3 ABT Based Boundary Metering ABT=Availability Based Tariff

4 4 ABT Based Boundary Metering And Boundary Metering Means ……….? #$#% O0oophs

5 5 ABT Based Boundary Metering So what is Boundary Metering? How it is different from ordinary metering?

6 6 ABT Based Boundary Metering To Understand Boundary Metering…. First understand what is meant by Metering of Electrical Energy?

7 7 ABT Based Boundary Metering Metering means, measurement of consumption of a consumer And it means measurement of the consumption at a point of supply to that consumer

8 8 ABT Based Boundary Metering Consumer Supply Line Consumption = Energy Recorded By the Meter A

9 9 ABT Based Boundary Metering Now Suppose………

10 10 ABT Based Boundary Metering Consumer Consumption = Sum of Energy Recorded By Meters A, B, C, D

11 11 ABT Based Boundary Metering Now let us further Suppose……… There is a Customer instead of Consumer of energy

12 12 ABT Based Boundary Metering Consumer V/s Customer

13 13 ABT Based Boundary Metering Consumer only consumes & Customer consumes as well as supply back

14 14 ABT Based Boundary Metering Customers need Bi-Directional Meters

15 15 ABT Based Boundary Metering Customer with Single Supply line needs Single Bi-Directional Meter Energy Consumption will be Net with Signs (+ve or –ve)

16 16 ABT Based Boundary Metering Sign Convention Net Energy Export = +ve & Net Energy Import = -ve

17 17 ABT Based Boundary Metering So in case of Customer with Multiple Supply Lines…………….Interface Points……….

18 18 ABT Based Boundary Metering Consumer Consumption = Vector Sum of Energy Recorded By Meters A, B, C, DEnergy Transaction = Net Energy Recorded By Meters A, B, C, D

19 19 ABT Based Boundary Metering Or Energy Transaction with Other Power Utilities So Boundary Metering Means Net Energy Transaction with a Customer

20 20 ABT Based Boundary Metering Now We Understood What is Boundary Metering Boundary Metering Means Measurement of Energy Transaction Across a Region Region in our case Normally means Another Power Utility or OA Customers

21 21 ABT Based Boundary Metering Any Questions Please?

22 22 ABT Based Boundary Metering Now let us come to what is ABT?

23 23 ABT Based Boundary Metering ABT = Availability Based Tariff

24 24 ABT Based Boundary Metering Now next obvious question is ………….?

25 25 ABT Based Boundary Metering What is Availability Based Tariff?

26 26 ABT Based Boundary Metering Understanding Availability Based Tariff

27 27 ABT Based Boundary Metering Purpose of ABT is to Bring in Grid Discipline

28 28 ABT Based Boundary 50 Hz => Hz => 294 RPM

29 29 ABT Based Boundary Metering Hz

30 30 ABT Based Boundary Metering SupplyDemand

31 31 ABT Based Boundary Metering Grid Security Grid Reliability

32 32 ABT Based Boundary Metering Tariff System Prevalent previously Bill of a Utility Energy Drawl Bill of a Generator Energy Produced

33 33 ABT Based Boundary Metering Hz50.30 Hz51.00 Hz50.30 Hz50.00 Hz49.80 Hz49.30 Hz48.50 Hz49.00 Hz49.50 Hz49.80 Hz50.00 Hz So Grid Frequency Used to………. Swing Wildly

34 34 ABT Based Boundary Metering Tariff System Prevalent previously No Incentives No Punishment

35 35 ABT Based Boundary Metering ABT = Grid Discipline

36 36 ABT Based Boundary Metering SupplyDemand

37 37 ABT Based Boundary Metering UFRs SCADA/ EMS Free Governor Operation Many other System for the purpose…

38 38 ABT Based Boundary Metering But Constraints Technical Political

39 39 ABT Based Boundary Metering Pseudo Balance ABT is an attempt to bring in some sort of balance between Generation & Consumption Using Money Power

40 40 ABT Based Boundary Metering So UI ……..

41 41 ABT Based Boundary Metering Unscheduled Interchange  UI for generating station is equal to its total actual generation minus its scheduled generation.  UI for distribution utility is equal to its total actual drawl minus its total scheduled drawl.

42 42 ABT Based Boundary Metering If Grid Freq is more than 50Hz then Overdrawing Utility will get energy at less rate and if it is more than 50.2 then it is free. If Grid frequency is less than 49.2 Hz then the overdrawing utility has to pay more & more for UI. Reverse conditions are applicable for Generating Stations.

43 43 ABT Based Boundary Metering Since the Original ABT Scheme there have been many Variations to bring in strict discipline and to stop profiteering by energy surplus utilities.

44 44 ABT Based Boundary Metering ABT ≡ Grid Discipline

45 45 ABT Based Boundary Metering So Friends…. This was a Short Primer On ABT

46 46 ABT Based Boundary Metering Now Back to …. ABT Based Boundary Metering

47 47 ABT Based Boundary Metering So ABT Based Boundary Metering means Boundary Metering based upon ABT type meters

48 48 ABT Based Boundary Metering ABT meters record Net Energy Transaction at a Interface point between the Power Utilities for each of 96 Blocks of 15 Minutes every day

49 49 ABT Based Boundary Metering ABT Meters are also called SEMs Special Energy Meters

50 50 ABT Based Boundary Metering In Punjab the Intra State transactions are to be metered based upon ABT Scheme in compliance to Punjab SGC

51 51 ABT Based Boundary Metering For Which SO&C Organization in PSTCL is going to implement AMR system based upon these meters

52 52 ABT Based Boundary Metering Any Questions?
