The company "AEM-technology" (part of the engineering division of Rosatom - Atomenergomash) is one of the main suppliers in the field of power mechanical engineering. The equipment is located at two sites: the branch of JSC "AEM-technology" "Petrozavodskmash" in Petrozavodsk and the branch of JSC "AEM-technology" "Atommash" in Volgodonsk.
Over the past several years, Atommash, the branch of JSC "AEM-Technologies" in Volgodonsk, has been buying electricity in the wholesale electricity and power market using automated commercial electricity measurement systems.
Due to the change in the requirements Commercial Operator of the Russian power system in the part of providing direct access from the server to the power meters it is necessary to modernize the system of the two main substation of the Atommash.
At the same time, due to the fact that the data of the system are used not only by the sales staff, but also by the staff of the power engineering department, the customer presented additional requirements to the system in the scope of displaying indications of current electricity parameters.
The previously used software did not provide such opportunities.
Features of the solution
SEDMAX software in the system provides:
- Collection of the data from the SET-4TM power meters;
- Visualization of the real-time electricity parameters (dispatching);
- Visualization of the electricity metering data;
- Transfer of XML reports to the Commercial operator.
As a result, at present, the system of the branch of JSC "AEM-technology" Atommash in Volgodonsk meets the latest requirements of the Commercial operator and provides in the basic kit (without the purchase of the additional modules) data for dispatching.
In addition to the key functionality, the problem of the satellites loss by the GPS receiver and time synchronization failures in the system was solved. SEDMAX, in the case of a GPS receiver failure, automatically switches the time synchronization source of the power meters to the certified servers of the Federal State Unitary Enterprise "All-Russian Scientific Research Institute of Physical, Technical and Radiotechnical Measurements").
Effects of the SEDMAX implementation
SEDMAX solution, which seamlessly integrates the features of power metering and dispatching, reserves time synchronization functions, has helped significantly save on the system's modernization. The plant did not have to buy a monitoring module and a time synchronization module for the previously used software, this decision reduced costs by 1.5 times.
One of the criteria for choosing the server software was the user interface, which should be clear for all stuff of the two plant departments without any special long-term training and habituation. This requirement is important due to the fact that after the years of using the previous software, the staff was unable to adapt to its "ergonomics". SEDMAX software was chosen, among others, for the clear and modern web-interface. This factor is important, because it affects the speed of the work of the staff and making decisions.
Dear Maxim Alekseevich!
In 2017, due to the change in the requirements of JSC "ATS" (Russian electricity commercial operator) in part of providing direct access from the server to the metering devices and the appearance of new requirements for the functionality of the software, Atommash decided to modernize commercial electricity metering system of two substations (GPP-1 and GLP-2).
Since not only the sales department specialists but also dispatchers are working with electricity metering data, the requirements for the software include displaying current values of the electricity parameters. To make it possible in previous system it was necessary to purchase an additional module. SEDMAX displays the current values of electricity parameters in the base version without the need for additional payments – both in the table form and on the mnemonic diagrams.
SEDMAX provide an interesting opportunity in part of reserving the time synchronization source. In the case of a GPS receiver fault or loss of satellites (a frequently occurring event), SEDMAX automatically switches the time synchronization of power meters to certified NTP servers of VNIIFTRI (All-Russian Scientific Research Institute of physics and radio engineering measurements), and simultaneously write these events in the system log.
At the present time, SEDMAX – as Atommash electricity metering software – provides:
- Data collection from the SET-4TM power meters;
- Displaying of current electricity parameters values (dispatching);
- Displaying of data on electricity metering;
- Transfer the data in XML format for JSC “ATS”.
Despite the long time with the previous software complex, the personnel could not get used to its interface. SEDMAX really has one of the most convenient and user friendly interface, with modern and customary web graphics, which makes work with the system not only convenient, but also fast.
I would like to express my gratitude to the Mavismart company for providing advice during the implementation process, for the readiness to solve the customer's tasks (including by customizing the software for the individual requirements of the plant).
