Automated modular boiler house of Penza heating networks

2024: Automation of the modular boiler house

The Company CIRCLE has carried out works to automate the modular boiler house (BMK) of Penza heating networks in the village of Neftyanik (part of the City District). Penza This boiler house was installed instead of the outdated one to improve the quality of hot water supply to the residents of the village. This was Circle of NPF announced on July 24, 2024.

The automated dispatching control system (ADMS) of the BMK is integrated into the common ADMS of the Penza heating networks. It was developed using typical technical solutions of KRUG company:  APCS of boiler houses , APCS of heating stations and ASDU by the facilities of the heat supply company.

The boiler house automation cabinet is equipped with an industrial DevLink-C1000 controller with I/O modules of the DevLink-A10 series, which collect, process and transmit data via the fiber optic communication line to the upper level of the system - to the dispatching center of the Penza heating networks. The dispatcher's AWS operates under the control of the Russian SCADA KRUG-2000.

This automation system allows the dispatching personnel to monitor the state of the technological process and equipment in real time, remotely control the operation of boilers, pumps and actuators, ensures the operation of emergency protection and interlocks.

KRUG developed design documentation, delivered automation cabinet, performed engineering and commissioning works. ALFA-NN (Nizhny Novgorod) completed the delivery of BMK and installation work at the site.

2020: Beginning of reconstruction of heating networks

In the context of accelerating housing construction in Penza, it was necessary to increase the capacity of the city's heating systems for reliable heat supply to the Lugometria microdistrict and part of the Arbekovo microdistrict. In this regard, the project for the reconstruction of Penza heating networks was launched, which includes the construction of a pumping station with the function of pumping network water into the supply pipeline. This was announced on August 5, 2020 by the Krug NPF company.

The main goal of the project is to minimize the cost of transportation and distribution of energy resources, improve the quality and reliability of district heating.

Within the framework of the project, the management of the Mordovian branch of T Plus PJSC made a decision on the need to develop an automatic control system for the newly erected pumping station (SS). This task was entrusted to KRUG as the main supplier of automation systems and the developer of ASDU JSC T Plus Penza Heating Network.

T Plus Penza Heating Network JSC is part of the Mordovian Branch of T Plus PJSC and supplies heat energy to Penza consumers, operates and repairs city lines of heat supply systems.

The design documentation of the SS automation system has been developed as part of two control cabinets based on industrial DevLink-C1000 controllers and DevLink-A10 series I/O modules. Both cabinets will be equipped with a touch control panel for field process control.

The DevLink-C1000 controllers will provide:

• control of the main equipment of the pump station: network pumps, including the frequency-control converter of one of the pumps, network valves and their bypasses
• control of cooling system of network pumps and other auxiliary equipment
• collection of data from heat exchanger and electric meters with their subsequent transmission to the upper level.

To implement the project at the upper level of the system, the Russian SCADA KRUG-2000 will be updated to the current version 4.3 on the existing server of the heating network manager, AWS of the heads of departments and servers of the archive database (ABD). To improve the reliability of operation, the system provides 100% hot redundancy of communication channels. The main channel is Ethernet, the backup channel is GSM.

The work was carried out jointly with Flagship Engineering, which designed the technological equipment of the station and the lower level of the APCS. KRUG has completed the design of the middle and upper levels of the system. As a result of such cooperation, a comprehensive project was developed that will further allow the successful introduction of an automation system for the pump station under construction.

2019

On January 31, 2019, KRUG announced the expansion of the automated dispatch system for heat networks in Penza on the basis of the KRUG-2000 software and hardware complex (KRUG-2000 CAS).

According to the company, TsTP-134, TsTP-144, TsTP-171, TsTP-160 and the TsTP-Training Plant are connected to the ASDU by the heating systems of Penza.

The automated dispatch control system of T Plus Penza Heating Network JSC has been developed using typical technical solutions: APCS of pump stations, APCS of heating stations and ADCS facilities of the heat supply company.

The DPT monitoring system provides:

• measurement of process parameters in the pipelines at the inlet and outlet of the TSC
• accounting of the coolant consumption and heat energy transferred to the heating and hot water supply system, technical accounting of cold water consumption for the own needs of the TSC
• alarm about violations of the specified value of the monitored parameters
• collection of operational and historical parameters from power converters and heat calculators SPT-961 and formation of operational lists based on them.

Two AWSs of dispatchers and AWS of the ETOiTAI chief specialist operate under the control of the Russian SCADA KRUG-2000. The web server allows system users to view information about the state of the heating network via the Internet. Data transfer between the DevLink-C1000 and SCADA controllers is KRUG-2000 carried out over the GSM/GPRS channel using a specialized protocol that allows working with slow and unreliable communication channels.

KRUG has delivered equipment and software, control cabinets, engineering and commissioning.

At the next stage, it is planned to integrate pump stations No. 1, No. 2, No. 4 into the system and increase the functionality of pump stations by connecting existing high-voltage frequency converters.
