• SCADA purpose of systems
• Automated Commercial Energy and Power Metering System (AICMS)

Automated information and measuring systems Pyramid (AIIS Pyramid) is a multifunctional automated system with centralized control and a distributed measurement function. Pyramid AIIS include measuring channels (IR) consisting of components (measuring instruments of the approved type) given in the type description on Pyramid AIIS. The specific composition, structure and configuration of each Pyramid AIIS instance is determined by the technical documentation for the tasks of a particular object.

Purpose of IIS "Pyramid"

Information and measuring control and energy consumption metering systems "Pyramid" (IIS "Pyramid") are designed for measuring electric energy and power, commercial and technical accounting of energy resources - automated collection, accumulation, processing, storage and display of information about energy consumption. IIS "Pyramid" are designed to create multi-level automated information and measuring systems (AIIS) of integrated metering of energy carriers, in particular, commercial metering systems of electricity and power (AIIS KUE), as well as for use in complexes of telemechanics multifunctional and automated process control systems (APCS ).

The results of measurements of the Pyramid IIS make it possible to determine the values ​ ​ of accounting indicators used in financial calculations in the wholesale electricity market, the retail electricity market and in bilateral contracts between suppliers and consumers.

IIS "Pyramid" allows you to collect data on the accounting of energy resources (electricity, thermal energy, gas, water and other energy resources) from the corresponding computers, correctors, flowmeters, meters.

Scope

• generating, grid and power sales companies;
• industrial and equivalent enterprises;
• small-engine consumers;
• household consumers;
• other energy-consuming (energy-supplying) enterprises, companies and organizations of all forms of ownership and departmental affiliation.

Structure

IIS "Pyramid" is assembled at the facility from hardware manufactured by various manufacturers and is a geographically distributed multi-level information and measuring system consisting, as a rule, of three functional levels:

1. Measuring and information complex (IIC) - automatic measurement at the measurement point:
2. * measuring transformers of current (TT) and voltage (TN);
3. * electric energy meters;
4. * sensors of different physical quantities and signals;
5. * flowmeters;
6. * computers;
7. * process control and control devices.
8. Information and computing complex of power plant (ICE) - information consolidation:
9. * data collection and transmission devices (DRC);
10. * industrial controllers;
11. * channel-forming equipment.
12. Information and computing complex (ICS) - automated collection, storage and processing of measurement results:
13. * server or industrial controller;
14. * time synchronization devices;
15. * channel-forming equipment;
16. * technical means for building a local area network (LAN).

Metrology

IIS "Pyramid" is certified and entered into the State Register of Measuring Instruments under No. 21906-11. The completeness of the system is given in the description of the type of measuring instruments. The verification procedure is approved by FSUE VNIIMS and allows verification of measuring channels during commissioning.

In accordance with the classification of measuring systems given in GOST R 8.596 "Metrological support of measuring systems. Basic provisions "(section 7), IIS" Pyramid "corresponds to class IS-2. Thus, with the help of the "typical" IIS "Pyramid, the problem of certification of" single "AIIS is solved without entering them into the State Register of Measuring Instruments.
