Specialists of JSC "NBI" completed a project to replicate a multifunctional optimization information and analytical system for JSC "Evraz NTMK" (Nizhny Tagil Metallurgical Plant).
The project implemented the following functionality:
1. NEW FUNCTIONALITY: Development of a prompt model for accounting and managing steam heat energy consumption:
- Performing calibration calculations of steam pipeline models;
- Performing predictive calculations of steam and heat energy consumption by consumers, standard and forecasted heat energy losses during steam transportation to consumers, and amounts of steam and heat energy supplied from the CHP plant.
2. Development of mathematical algorithms for calculating technical and economic indicators::
- Development and implementation of algorithms for calculating actual, nominal, standard and forecasted technical and economic indicators;;
- Implementation of an algorithm for calculating components of heat efficiency reserves;
- Generation of report forms;
- Providing users with operational information displayed on mimic diagrams.
3. Development of optimization algorithms for:
- Selecting optimal equipment composition;
- Optimal distribution of electrical and thermal loads of equipment operation.
4. Automatic collection, processing and storage of information:
- Implementation of an algorithm for unified collection of technological information data into the EMAS.TEP system;
- Storage of all information in a unified repository.
5. "Dispatching":
- Monitoring and control of planned optimal equipment operating modes.
Project goal: Replication of the solution implemented at the West Siberian Metallurgical Plant, implementation of an information analytical system for modeling operating modes and planning optimal modes, which will comprehensively improve CHP plant efficiency in producing and supplying heat and electric energy, select optimal power plant operating modes to maximize profit through redistribution of equipment electrical and thermal loads.
During project implementation, difficulties arose, such as increased workload for developing and configuring data transfer software from CHP plant information systems to a unified technological information service, which the project team successfully addressed using Apache Kafka software.
Of the project's successes, one can note the new functionality implemented based on EMAS.TEP and tested in "live" mode — this functionality enables the creation of a module for accounting and consumption of thermal energy in a pair. The calculation results help identify problems in the energy efficiency of the heat carrier supplied to consumers. As a result of the test operation, for example, it was possible to accurately identify locations where consumers had issues with thermal insulation on pipelines.
Client: “EVRAZ Nizhny Tagil Metallurgical Plant” is one of the largest metallurgical plants in Russia with a full production cycle, including coke-chemical, blast furnace, and converter production, as well as several rolling mills.
Facility: CHP of JSC “EVRAZ NTMK” — a structural subdivision of the company, also serves as a power plant for industrial and urban use, supplying thermal energy to the industrial and communal loads of the plant, housing and utilities consumers in the city of Nizhny Tagil, as well as a nearby industrial enterprise.
