BSCP601 Protocol Test Script - CoP 11 Asset Metering

Guidance Note

Introduction

This document is provided by Elexon as a sample test script for the protocol approval of Half Hourly Asset Metering Equipment used for Settlement purposes for Asset Metering Types in Code of Practice (CoP) Eleven. In most circumstances this test script will satisfy the requirements for protocol testing in accordance with BSCP601. However, in some cases, changes may be necessary to accommodate alternative test methods but these must only be made with the prior agreement of Elexon and before testing commences.

Asset Meters are split into three categories and only Asset Meters in categories 2) and 3) are relevant to this document:

    1. An Asset Meter approved for use in CoP 1, 2, 3, 5 and 10 that is a Half Hourly Integral Outstation Meter;

    2. An Asset Meter whose primary purpose is the measurement of Active Power and/or Active Energy that is not an approved Half Hourly Integral Outstation Meter under 1) above; and

    3. An Asset Meter whose primary purpose is not the measurement of Active Power and/or Active Energy and is not a Half Hourly Integral Outstation Meter. These Embedded Metering Devices are embedded within equipment used for purposes other than the measurement of Active Power and/or Active Energy, such as an EV charging unit or a small-scale domestic battery storage unit.

For Asset Meters in category 1) the relevant Data Collector must have completed Protocol Approval to the requirements of BSCP601 for Protocol Testing of Metering Equipment for CoPs 1, 2, 3, 5 and 10. A sample test script for this can be found on the Elexon website (BSCP601- Protocol Test Script - CoPs 1, 2, 3, 5 and 10).

Please return the completed test script to the metering team at Elexon for review and agreement - metering@elexon.co.uk. Once agreed, the test script may be used by the Protocol Testing Agent.

Testing Basic Requirements

Where the Asset Meter has the functionality to store data, the samples of Asset Meters are to be pre-loaded with a minimum of 20 days of non-uniform1 data before any testing is carried out. Once populated with data Asset Meters are to be installed in a suitable test environment and connected to communication equipment which enables remote data collection from the Half Hourly Data Collectors (HHDC) or Asset Metering Half Hourly Data Collectors (AMHHDC) (i.e. the HHDC or AMHHDC are the Protocol Testing Agent) system as well as local or remote interrogation using the Asset Meter manufacturer’s software.

Where the Asset Meter does not have the functionality to store data, the samples of Asset Meters are to be installed in a suitable test environment and connected to communication equipment which enables remote data collection from the HHDC or AMHHDC (i.e. the HHDC or AMHHDC are the Protocol Testing Agent) system as well as local or remote interrogation using the Asset Meter manufacturer’s software.

Result (Pass/Fail)

To ensure that the HHDC’s/AMHHDC’s system correctly collects data from the Asset Meter.

Populate the HHDC’s/AMHHDC’s system with the correct standing data and correct access protocol and collect all4 data for a minimum of one day. Then, using the Asset Meter manufacturer’s software, collect the same data and compare the results.

Where the Asset Meter does not have internal storage capability data will have to be gathered over the period of one day as a minimum.

Where the Asset Meter does not record in 30-minute Demand Period format the data must be converted to this format.

Both sets of data and time stamps must be the same.

Data should also match the known load injected when converted into 30 minute Demand Period format.

Collect the same data from test DR1-1 with the correct access protocol. Then, using the Asset Meter manufacturer’s software, collect the same data and compare the results.

The data and time stamps collected must be the identical to those collected in test DR1-1 and both sets of data and time stamps must be the same as those from the Asset Meter manufacturer’s software.

1 The requirement for pre loading Asset Meters with non-uniform data is so that the data, when collected, can be differentiated from other half hour data stored in the Asset Meter. This should include data on all channels configured in the Asset Meter i.e. can include Active Import, Active Export, Reactive Import, Reactive Export, Active Import related Import kvarh, Active Import related Export kvarh, Active Export related Import kvarh, Active Export related Export kvarh where available

2 HHDC/AMHHDC Systems may be linked to PCs set to British Summer Time but the underlying HHDC/AMHHDC System must be synched to UTC.

3 UTC means Co-ordinated Universal Time which bears the same meaning as in the document Standard Frequency and Time Signal Emission, International Telecommunication Union - RTF.460

4 All data is dependent on the design of the Asset Meter and can include Active Import, Active Export, Reactive Import, Reactive Export, Active Import related Import kvarh, Active Import related Export kvarh, Active Export related Import kvarh, Active Export related Export kvarh
