5.4 CDCA-I004: (output) Notify New Meter Protocol


Interface ID:

CDCA-I004



User:

MOA


Title:

Notify New Meter Protocol



BSC reference:

CDCA SD 6.1-4



Mechanism:

Manual


Frequency:

As required



Volumes:

One or two per year



Interface Requirement:

The CDCA will inform all MOAs registered with the CRA of any newly approved protocol within seven days of approval;


The data will include

protocol name

effective from date


Physical Interface Details:


5.5 CDCA-I005: (input) Load New Meter Protocol


Interface ID:

CDCA-I005



Source:

MOA or Protocol Provider



Title:

Load New Meter Protocol



BSC reference:

CDCA SD 6.1-4, CP756



Mechanism:

Manual, by email, letter or fax



Frequency:


Volumes:

One or two per year



Interface Requirement:

The CDCA receives notifications of newly approved protocols from an MOA or other Protocol Provider, so that the protocol can be loaded onto its data collection systems, such that data can be collected from the meter.


Details of the interface depend on the data capture device used. This is likely to be MV-90.
The CDCA shall be responsible for procuring whatever translation interface modules or other device drivers necessary to allow the data capture device to remotely interrogate the metering equipment.



Physical Interface Details:

A flow description is not provided for this interface, as different protocols will be provided.


5.6 CDCA-I006: (output) Meter Data for Proving Test


Interface ID:

CDCA-I006



User:

MOA


Title:

Meter Data for Proving Test



BSC reference:

CDCA SD 7.2



Mechanism:

Manual


Frequency:

As required



Volumes:

Low


Interface Requirement:

In the process of proving tests for meter data collection, the CDCA transfers the test data received to the relevant MOA responsible for that Metering System for validation of accuracy.


The data content will be a subset of CDCA-I008

Physical Interface Details:



5.7 CDCA-I007: (output) Proving Test Report/Exceptions


Interface ID:

CDCA-I007



User:

MOA, BSC Party



Title:

Proving Test Report/Exceptions



BSC reference:

CDCA SD 7.6



Mechanism:

Manual


Frequency:

As required



Volumes:

Low


Interface Requirement:

In the process of proving tests for meter data collection, the CDCA reports any proving, validation and communications errors associated with any Metering System to the relevant MOA. and a duplicate report to the registrant BSC Party.





Physical Interface Details:



5.8 CDCA-I008: (input) Obtain metered data from metering systems


Interface ID:

CDCA-I008



Source:

Physical meters



Title:

Obtain metered data from metering systems



BSC reference:

CDCA SD 8.1- 8.4, 8.7



Mechanism:

Meter System interface



Frequency:

Daily


Volumes:

1100 - 5000 per day



Interface Requirement:

The CDCA collects meter period data remotely over a communications link, via a data capture device (MV-90).


For each registered meter the CDCA shall collect and record meter period data as follows:

a). Export Active Energy;

b). Import Active Energy;

c). Export Reactive Energy; and

d). Import Reactive Energy;
The CDCA shall collect meter period data relating all Main and Check meters, and/or the corresponding data collector outstation registers, where installed and operational, and which are used for settlement purposes.
The CDCA shall record and store all meter period data collected from Metering Systems. The data items recorded and stored shall include, but not be limited to the following:-
Date and Time of Reading

Metering System Identifier

Settlement Date

Outstation Id

Channel Number

Measurement Quantity (Active Import , Active Export, Reactive Import, or Reactive Export)

Main/Check Indicator

Settlement Period (46, 48 or 50 occurrences)

Meter Reading Volume

Meter Reading Status


Meter Reading Status can be one of:

A - Valid meter data

B - Invalid meter data

C - Unavailable meter data


Note that there may be more than one Check channel for the same Main, for a given Measurement Quantity.
This flow includes data collection from all metering systems registered with the CRA, including

those associated with both External Interconnectors (points of connection between transmission

networks) and Internal Interconnectors (points of connection between distribution networks).


Physical Interface Details:

No physical structure is defined as protocols vary
