2023

Completion of AIIS UWC technical upgrade

The KRUG company on April 24, 2023 announced the completion of work on the technical re-equipment of the automated information and measuring system of the combined water treatment complex (AIIS UWC) of the Saransk TETs-2.

AIIS UWC of Saransk TETs-2 operates on the basis of the KRUG-2000 software and hardware (software and hardware) complex (PAK PTK KRUG-2000).

The existing control cabinets were converted with the installation of DevLink-C1000 controllers and DevLink-A10 I/O modules from the PAK CAS KRUG-2000. The controller equipment operates under the control of the real-time controller system (RVCC) developed by NPF KRUG.

Two AWS of operators with the installed SCADA KRUG-2000 one perform functions of collection, processing, visualization and archiving data from lower level sensors, as well as functions of control of actuators and pump units. The engineer's AWS provides control and correction of software controllers and operators' AWS.

The work was carried out systematically and divided into stages for three years without stopping the process of water treatment of the thermal power plant.

KRUG has been working at the facilities of the Saransk TETs-2 since 1999. During this time, together with the specialists of NPF KRUG, the reconstruction and modernization of automation tools for the technological processes of the main equipment is being carried out sequentially

Completion of technical re-equipment of ASKUTE

Completed design work on technical re-equipment of automated system of commercial metering of thermal energy (ASKUTE) of the Saransk TETs-2, which performs the functions of integrated technical and commercial metering of thermal energy/heat carrier. Accounting is carried out in accordance with the rules of commercial accounting of heat energy and heat carrier (Resolution Government of the Russian Federation No. 1034). The company Circle announced this on February 7, 2023.

The developed design documentation provides for the replacement of the outdated equipment and upgrade software of the upper level of the system. The modernized ASCUTE will ensure the production of cash calculations according to energy resources with consumers, as well as operational control functions heat production and heat consumption by subdivisions and facilities of the enterprise.

Operational and commercial information is collected by data collection controllers DevLink-S1000 (together with DevLink-A10 I/O modules) from thermal energy metering devices of geographically distributed consumption facilities. Controlled parameters: flow rate, pressure and temperature of the supplied coolant consumers, as well as the supply of additional water to the thermal power plant. Information is accumulated on the data collection server and displayed on the AWS operators with SCADA KRUG-2000 installed. Then all information is transmitted to automated information-measuring system of technological and commercial metering of CHPP (AIIS TiKU).

Factory network users: AWS of the director, chief engineer, head of PTD, Head of CTC and Head of CTAI. All information is stored for 5 years and can be provided to management, employees and consumers in the form of reports, tables and graphs.

Reconstruction and modernization are being carried out consistently at the Saransk TETs-2 main equipment and means of automation of technological processes. With with the participation of NPF KRUG, SAUGs of steam boilers TP-47 st. No. 5 and No. 6 were put into operation, boilers PK-19 st. No. 1 and No. 2, SAUG boiler units PK-19 st.
