Purpose of the system

ASKUE is designed for:

Estimated accounting of electricity consumption of OJSC "VolMet"

Automatic collection and processing of information from energy consumption meters in the enterprise;

improving the accuracy of energy metering through the use of modern metering devices and the use of digital technologies for measuring, collecting and processing data;

Generate all necessary accounting documentation and event log

synchronization of DRC time and counters.

Composition of automation objects

The objects of automation of OJSC "VolMet" are design points of electricity metering located in electrical installations on the territory of the enterprise, as well as metering points located at the supply substations of RUP "Grodnoenergo" and at subcomponents "

Design solutions

3.1. Structure and functioning of ASCUE

Structural diagram of ASKUE system construction is given in the drawing

3502.05ASKUE sheet 3.

The complex provides:

compliance with the requirements of the "Rules for the use of electric energy" regarding the organization of commercial accounting of electric energy;

centralized collection of information on energy consumption;

data archiving;

displaying the collected and processed information on the operator's AWS;

calculation of the combined maximum power consumed by the enterprise during the maximum load hours of the power system;

ASKUE system consists of

- microprocessor counters of the electric power CC3015.1/U, CC3015.1/0 and CC30110.1/U and SS101140Sklassov of accuracy on accounting of active energy 0.2s, 0.5S and 1.0 respectively,

- current transformers, RS485 communication lines, DSS "AISE 1.03," GSMmodem for synchronization with the BelGIM exact time server, BMP16 U transceivers for obtaining information from dispersed counters via radio channel.

The central transceiver is also installed in the DRC cabinet and connected to the DRC controller via RS485 channel.

To organize information collection in DRS DB from counters located on PS35/10 "Zapadnaya" (fid. 1, fid. 24), a communication channel is organized over the Internet with the data collection server PSDTU RUP Grodnoenergo.

The system is designed for 24-hour continuous operation.

ASCUE technical and software tools

4.1.List of technical and software tools used to build ASKUE.

AC electric energy meters of static type "SS301," Republic of Belarus. Registered in the State Register of Measuring Instruments of the Republic of Belarus under No. RB 03 13 1316 04. Certificate on type approval of measuring instruments of the State Standard of the Republic of Belarus No. 3126 dated 28.12.2004

Data collection and transmission device of DSS "AISE 1.03" with software, manufactured by PSDTU RUP "Grodnoenergo," Republic of Belarus. Registered in the State Register of Measuring Instruments of the Republic of Belarus under No. RB 03 13 2757 05. Certificate on type approval of measuring instruments of the State Standard of the Republic of Belarus No. 3702 dated 27.12.2005 .

Stages of ASCUE creation

The stages of making ASCME include:

Design works.

Dismantling-installation, commissioning works.

Putting the system into pilot operation.

Commissioning.

System reliability

Reliability indicators are adopted for ASKUE without taking into account the reliability of external devices (electrical cables).

Indicators of hardware reliability of ACSUE CTS are mean time between failures and average recovery time of devices implementing this function.

Provision of the specified reliability indicators shall be performed in accordance with the power supply characteristics and the state of the environment to the specifications of the system manufacturer.

The average service life of the system shall be at least 10 years. The suitability for operation of the system after this period is established by a commission appointed by the management of the enterprise with the participation of the System Supplier.

At the design stage, reliability indicators in terms of reliability and durability shall be evaluated by the Supplier's analytical method.

The following distribution of failure probability between components can be adopted when evaluating the reliability indicators of the ASKUE system:

system - 30%;

external (relative to the system) - 70%.

Patent Reference

All technical means used as commercial are included in the Gostreestre of the Republic of Belarus and comply with the technical specifications. Technical means used for technical accounting shall be purchased and installed by organizations that have permits for special types of work.

Branded software and math must be purchased under licenses, and special - under contracts with contracting organizations that also have licenses to carry out such work.

There are no patentable solutions in this project.

Inventions of other organizations are not applied.

Objects of new technology, in addition to typical and reusable solutions, were not developed, as a result of which there was no need to study patent materials and to compile a patent form.
