    ABT Based Boundary Metering

    So what is Boundary Metering?

    How it is different from ordinary metering?

    ABT Based Boundary Metering

    To Understand Boundary Metering.

    First understand what is meant by

    Metering of Electrical Energy?

    ABT Based Boundary Metering

    Metering means, measurement of

    consumption of a consumer

    And it means measurement of the

    consumption at a point of supply tothat consumer

    ConsumerMeter A

    Supply Line

    Consumption = Energy Recorded By the Meter A

    Now Suppose

    10

    ABT Based Boundary Metering

    ConsumerMeter A

    Meter C

    Meter B

    Consumption = Sum of Energy Recorded By Meters A, B, C, D

    Meter D

    ABT Based Boundary Metering

    Now let us further Suppose

    There is a Customer instead of

    Consumer of energy

    Consumer V/s Customer

    Consumer only consumes

    &Customer consumes as well as supply

    Customer with Single Supply lineneeds Single Bi-Directional Meter

    Energy Consumption will be Net withSigns (+ve or ve)

    Net Energy Export = +ve

    & Net Energy Import = -ve

    So in case of Customer with Multiple

    Supply Lines. Interface Points.

    ConsumerMeter A

    Meter C

    Meter B

    Consumption = Vector Sum of Energy Recorded By Meters A, B, C, D

    Meter D

    Energy Transaction = Net Energy Recorded By Meters A, B, C, D

    OrEnergy Transaction with Other Power

    Utilities

    SoBoundary Metering Means Net Energy

    Transaction with a Customer

    ABT Based Boundary Metering

    Now We Understood What is BoundaryMetering

    Boundary Metering Means Measurement ofEnergy Transaction Across a Region

    Region in our case Normally means AnotherPower Utility or OA Customers

    If Grid Freq is more than 50Hz thenOverdrawing Utility will get energy at lessrate 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 forGenerating Stations.
