Control Department - Data Processing and Automation
Industrial automation is the use of control systems, such as computers or robots and information technology, to control various machines and processes in the industry instead of humans. The biggest advantage of automation is the reduction of labor. Also, automation is used to save energy and materials to improve quality and accuracy. According to the requirements of the country’s electricity industry, this company established the workshop of electricity and precision instruments in 2013 with the aim of self-sufficiency and making sanctions ineffective in order to repair and supply electrical equipment and precision instruments of power plants and refineries. This workshop has taken effective steps with the cooperation of electrical experts in the field of manufacturing, calibrating and repairing all kinds of pressure switches, temperature, all kinds of gauges and servo valves, pneumatic, hydraulic, electric actuators and all kinds of control valves and speedtronic cards.
The Capabilities of the Precision Instrument Control Department, Data Processing and Automation
- Major repairs of the precision instruments department of all gas and heating power plant units
- Implementation of DCS, PLC, HMI projects
- Monitoring and control of information and transmission in the form of network and wireless
- Carrying out smart networking projects
- Hardware design of control system and data processing system in different projects
- Receiving data from sensors, sending commands to operators
- Drive motors and other electric and electronic circuits
- Starting AC and DC motors
- Different drivers and soft starters and servo motors and step motors
Replacement of Gas and Steam Turbine Control Systems
Due to the long life of a large number of power plants and industries in the country and as a result the control systems of these power plants are old and worn out and common problems in this type of control systems include:
- High number of unwanted exits
- Troubleshooting problems
- Weakness in monitoring
- Low level of protection
Gas Turbine Control System
This control system is completely economical and according to the needs and orders of the employer, it can completely replace the old system, or in connection with other parts of the old control system, it can replace a part of the old system.
The design of this control system is well adapted to all kinds of old control systems, including hydraulic, pneumatic, and electro-hydraulic.
In the case of complete replacement of all control-protection loops and turbine sequences, they will be installed on a platform, and there will be a minimal need for intermediate equipment, and it will greatly reduce the final cost of the project.
This control system is designed based on DCS and is completely flexible, and the protection degrees required by the system or the items desired by the employer can be added to the system, such as (SIL & redundancy level)
Steam Turbine Control System
This control system in the steam turbine sector can replace old types of steam turbine governors, including electronic or hydraulic ones, or replace all protections and turbine start-up steps according to the client’s needs.
In case of complete replacement of the control and protection facilities, a visa will be added to the system, including :
- Automatic startup capability
- Load sharing
- Automatic synchronization
- Full monitoring
- Single or double channel overspeed protection
Replacement of Excitation System
Due to the passage of time, many stimulation systems in various industries such as power plants, sugar factories, and other industries are worn out, and due to this wear and tear, the troubleshooting process takes a lot of time, and in many cases, spare equipment cannot be provided. This company is ready to replace the old and analog excitation systems with modern systems with much more monitoring and protection capabilities in the shortest possible time.
Among the advantages of the alternative system, the following can be mentioned :
- Minimal need for repairs and shortening of troubleshooting time
- The possibility of connecting to automatic synchronous systems and active and reactive power control
- Increasing the safety factor of the system
- The possibility of using existing equipment and reducing optimization
- The possibility of removing the exciter and replacing it with static excitation
