Regular Automatic Backup of All Data At the Desired Time
Optionally, AMR Centre administration also ensures the following:
Administration of software components (versions of application software and firmware) and all the settings of AMR system, i.e. its components.
Automatic monitoring of parameters and performances of AMR Centre operation, analysis and generation of the reports on the system operation, as well as informing the system operator on the observed problems.
Management (generating, taking over, archiving, monitoring and controlling the access) of the documents required for proper system operation.
Data Reading/Collection and Archiving Functions.
Data collection/reading and memorising function collects data automatically in an efficient and reliable manner from the concentrator/meter and memorises (archive) them in a corresponding data base or performs instant reading of the concentrator/meter upon user request.
Reading function is realised through corresponding reading programmes/sequences.
According to the amount of concentrator/meters being read we differentiate:
Reading of Individual Concentrator/meter
Reading of the Group of Concentrators/Meters
According to the reading frequency we differentiate:
Automated Reading According to the Sequence
Reading On Request
Periodical Reading on Request
Special Reading on Request
Data collected automatically according to the sequence set in advance (no difference is made whether these data are collected from the concentrator or via direct communication with the meter) include:
Daily Register Values
Meter States
Electricity Quality Log
Event Log
Load Profile
Hourly Register Values
State of Monthly Accounting Registers
Time and Date
Data collected from the meter on request (via concentrators or direct communication with the meter) include the following, in addition to data collected automatically:
Effective Voltage Values Per Phases At the Moment of Reading
Effective Current Values Per Phases At the Moment of Reading
Current Power – (Load Power At the Moment of Reading)
Tariff Programme
Integration Period for 15-Minute Maximum Power
Consumption Management Parameters
Parameters for Voltage Thresholds Within Electricity Quality Log
Parameters or Time Intervals of Profiles
Parameters for Registers Within Profiles
Parameters Related to the Presentation On Meter Display
Archive States of Accounting Registers
Current State of Bi-stabile Switch
Meter Software Version
Factory Number and Type of Meter
The data is transmitted together with the time stamp of data creation.
Data read according to the sequence from the concentrator (in addition to data obtained by meter reading) include:
Statistics of Communication
Emergency and Regular Reports
Data read from the concentrator upon the request include:
Concentrator Data Archive
Reading Programmes/Sequences
Management/Parameterisation Programmes/Sequences
Programmes/Sequences Execution Priorities
Communication Routes
Concentrator Response Time and Frequency Parameters
Communication Parameters of the Concentrator
Current Date and Time
Other Concentrator Parameters
Concentrator Software Version
Records on Concentrator Parameter Changes and Adjustments
Data collection/reading function offers reading control with the display of percentage of successfully read meters/concentrators in every reading.
Reporting functions.
Reporting functions are divided in:
Reports with Analysis of Statuses and Alarms
This type of reporting functions processes alarms and statuses of meters/concentrators, event logs, with the making of corresponding reports after finding corresponding alarms, statuses and events.
These functions process events and alarms related to the disruption of meter integrity (e.g. opening of termination cover), as well as attempt or disruption of data integrity in meters or concentrators themselves (e.g. meter reprogrmming attempt).
Result of such reports is the daily, i.e. periodical report on the state clearly showing all alarms, statuses and events and on which meters, representing the basis for further action on these meters.
Reports on Electricity Quality
This reporting function executes analysis of voltage circumstances on meters themselves since there are corresponding records in the electricity quality log recording voltage drop/overvoltage below/above defined voltage thresholds and supply interruptions. In this way the function would indicate poor voltage circumstances with one or a group of customers and it represents the reason for the crews to go out into the field.
Reports Related to Parameterisation and Management
In addition to the reports which were the consequence of parameterisation/management over System elements, it is also necessary to anticipate a number of reports.
Due to great significance, there is a report on disconnected customers, i.e. the report on the management of bistabile switch which needs to contain the date when the action was set and when action execution confirmation arrived.
Communication Reports
Successfulness statistics of communication between system elements represents a special whole within the reporting functions.
Control Reports
These reports indicate real time detuning or disagreement in tariff programme. Results of these reports represent the basis for the setting of automatic parameterisation over elements where detuning has been noticed.
Reports Generated by the Concentrator
Reporting functions also support the presentation of reports the concentrator sends upon emergency reporting request to AMR Centre.
Data and Information Exchange Functions with Other Information Systems and Subsystems of Electric Utility.
Data on metered consumption to be transferred to other systems are as follows:
Data on metered consumption for households, where there are no requirements in terms of requested load on hourly level; data on consumption is transferred in the end of the daily accounting interval.
Data on metered consumption for industrial customers, where there are requirements in terms of requested load; data on consumptionis transferred either as 15 or 60-minute data in the end of the daily accounting interval.
All data transferred via this data transfer method is related to the same calendar day. Finally, transferred parameters have identified information in their heading reporting to other systems the priority during data upload for more subordinated devices simultaneous data transfer is requested.
Priority is based on time and date of meter data occurrence.
Robust protocol library for various types of DCUs and electronic energy meters;
DLMS/COSEM, IEC61870-5-102 compliant.
