Many years of experience in creating automation systems, the use of modern technical solutions from the world’s leading manufacturers of industrial automation components, automation and power supply systems, allows us to create control systems that meet the highest requirements of customers.
We create automation systems for energy, industrial and municipal enterprises, as well as any other objects that have an approved technical task and an agreed technological process.
We provide a full life cycle of automation systems – from design, equipment manufacturing, to commissioning, commissioning and support throughout the entire period of operation.
Our online control systems carry out dispatching, monitoring of objects and implement effective algorithms.
At power facilities, our control systems perform, among other things, group control and distribution of active and reactive power, as well as frequency and voltage regulation on bus sections, control the level of power flows into / out of the network, and provide emergency response.

Control cabinets
We carefully treat every stage of creating a control cabinet – from design, selection of components, assembly and installation, to a 100% check of each product.
DESIGN
The design team designs the cabinet in stages:
- develops the structure of the management system;
- creates circuit diagrams of cabinets;
- selects components of automation, automation and power supply systems;
- develops installation drawings of equipment in a three-dimensional design environment;
- develops software;
- develops operational and accompanying documentation.
ASSEMBLY
During installation, a lot of attention is paid to the quality of connections, ease of use and maintainability:
- careful selection of wire cross-sections;
- convenient and easy-to-read marking of wires and automation elements;
- cutting and termination of wires, using special tools;
- the use of wires of the appropriate color, depending on the purpose.
EXAMINATION
All cabinets undergo a thorough multi-level check using special stands:
- development of technological inspection charts and QCD checklist for each type of cabinet;
- direct control of each manufactured cabinet according to the checklist;
- coordination and approval of the QCD control sheet on the acceptance of the cabinet.
The control includes, among other things: control by the lead designer, tests under voltage, verification and calibration of each measuring and control signal, downloading controller software, etc.
Tasks solved by control systems of our development:
1. DATA COLLECTION
Data collection is performed:
– from local ACS (ACS of engines, ACS of boilers, etc.);
– from instruments and meters (power meters, flow meters, etc.);
– from sensors and devices (4-20mA, 0-10V, pulse signals, counters, HART, IO-Link, etc.).
Data is received using industry-standard interfaces and exchange protocols:
2. Data storage
– Long-term data storage (at least 1 year, depending on the storage capacity);
– storage of a large number of tags (more than 1,000,000 tags);
– high resolution of trend storage (from 0.01% of the measurement range, up to a cyclic recording with a period of 20 ms);
– storage of data with timestamps, accurate to 1 ms;
– preservation of warning alarms, personnel actions (Audit), generation of user reports.
3. Visualization
- high rendering performance, high image refresh rate, fast transition between mnemonic diagrams;
- intuitive interface.
инINTERFACE
Hints, comments (including operator comments), action confirmation windows
ACCESS
Requirement to enter a password, access by key, differentiation of functional rights
AUTOMATED WORKPLACE
Unlimited number of workstations, large video panel from 50 .. 75 inches
MONITORING
Remote monitoring via the Internet – using secure communication channels
4. Generation control
We know how to manage power plants and provide a wide range of mechanisms and control algorithms
POWER FLOW
Regulation of power flows – at control points with the help of regulatory influence on power units (increase/ decrease power; stop/start additional power units, etc.)
EMERGENCY ALGORITHMS
Automatic transfer of reserve, automatic load shedding, prevention of positive power flow into the network and much more
REGULATION
Automatic group control of frequency and power (possibly by bus sections, by groups, control by transformers, etc.)
POWER UNITS OPERATION MODE
Automatic detection and fast switching of the operating mode of power units (parallel with the network / island mode)
SYNCHRONIZATION
The use of modern high-tech synchronizers, type B&R X20CM0985-1
PRRO
Participation of the energy complex in the overall primary frequency regulation
5. Other algorithms
On the basis of the same automation tools, taking into account the wishes and needs of the Customer, we manage auxiliary equipment and monitor local control systems (such as, for example, ventilation of the administrative building,
central heating unit, oil facilities, compressor room, etc.)
regulation of power module power depending on the state of technical means (overheating of the cooling liquid, manual reduction of the rated power of the machine, etc.)
control of ventilation of turbine halls and rooms (maintaining temperature and overpressure, maintaining process air flow, winter/summer mode, etc.)
implementation of additional equipment protections (for example, taking into account features of the relationship between equipment, or “gaps” in the design, etc.)
accounting of running time, engine hours, output of reminders about the need for maintenance, a report on maintenance and engine hours
6. Integration into external systems
Report
Excel, HTML, tables, reports and more
OPC UA
Integration into higher-level systems (ERP, OPC UA, Web-API, etc.)
VPN
Remote monitoring and technical support via the Internet (VPN, SSH, etc.)
IEC
