To become a participant in the wholesale electricity and capacity market. It is necessary to comply with the requirements of the WECM , which are establish by law. They also apply to technical equipment, primarily to commercial metering equipment. The latest changes were adopt by the “NP Market Council” on March 9, 2021. Which is enshrin in the Regulation on the procdure for obtaining the status of a wholesale market entity and maintaining a register of WECM entities. The document. Was develop in accordance with RF Government Resolution No. 1172 of December 27, 2010, which approves the rules of the WECM and amendments to acts on its functioning.
The current technical requirements for the AIS KUE
Appendix No. 11.1 to the said Regulation. Due to south korea phone number list the changes, there is a need for a widespread replacement of metering devices, which is ongoing and will continue until 2029.
In connection with the modernization of the wholesale electricity and capacity market systems, the A1800 electric meters have come to the fore. They have replaced the existing EuroAlpha (Alpha A1600), A2 and A1 meters. The A1800 meters have advantages over previous generations and devices from other manufacturers.
Advantages of Alpha A1800 meters when upgrading wholesale electricity and capacity (WEM) systems
Increased storage depth
If the meter designation contains the letter X, this indicates the presence of a 1 MB memory expansion board. It provides an increased storage freelance professions in poland – definition and list depth, which in a typical mode for 4 load graphs with 30-minute intervals is 1800 days. For comparison, the main memory (designated L) is 128 KB. With the same parameters, the storage depth in this case is 180 days.
Increased memory is relevant for large generating objects with small accumulation intervals of 1.3 minutes on average.
Working in multiple protocols
Another advantage of the A1800 is its ability to work in singapore lead several protocols. In the standard version, this is ANSI, in other modifications – Modbus RTU and DLMS (in the designation, the number 1 or 5 is added to the indexes of digital interfaces).
Recording additional information (telemetry)
Using the open, efficient ANSI protocol, you can read not only measured energy and power data, but also additional indicators (up to 24 parameters per second):
Accumulation of up to 32 parameter graphs
Another advantage of the A1800 meter is the ability to calculate. Up to 32 parameters of physical quantities of a three-phase electric network. The interval duration for each of the 2 sets with 16 graphs is set programmatically. And is in the range of 1-60 minutes.
