f) Industry workstation

We provide complete distribution automation systems in partnership with PSI. alfanar's outstanding manufacturing capabilities and PSI's unique global supply capabilities enable us to provide world-class distribution automation systems.

PSI control has been designed for sophisticated and economic management of:

• Electrical transmission networks
• Regional electrical distribution networks
• Networks for the multi-utility supply of electricity, gas, district heating, and water
• Railway electricity networks
• Industrial networks

The PSI system provides the following special features:

Structural Flexibility

Maximal structural flexibility in the control system design. A PSI control system is not limited in terms of location. It is possible to sub-divide the control system architecture and to set up sub-systems in different locations. This is particularly beneficial in terms of security and redundancy.

Highest system performance by parallel processing

The parallel processing provides the shortest possible system response and processing times, even during worst-case situations and extreme information throughput.

Unsurpassed Availability

Parallel processing structures can be added redundantly as needed without affecting the system performance. The PSI control redundancy management handles all error situations even during the occurrence of simultaneous errors or multiple errors. As long as one component on each system level remains functional, the entire system remains operational without limitations. In most of the implemented projects, availability of nearly 100% is achieved.

System virtualization provides additional potential for savings

Multiple sub-systems running in separate hardware components can be virtualized and run on less hardware.

Smart SFA-RM, main component:

RTU (Remote Terminal Unit) SPRECON-T3:

The smart ring main unit has an integrated remote terminal unit (RTU) to allow remote monitoring and control via the control center. The connection between the local RTU and control center is established over a secured virtual private network (VPN) connection.

Supported Protocols in SPRECON-T3:

Power supply and batteries:

The smart ring main unit is self-powered. The power supply comes from the control power transformer which is connected directly to the live bus and provides the low-voltage circuit with 220VAC. All used equipment, such as auxiliary relays, remote terminal units, and modems use 24VDC which comes from the AC/DC converter. This unit also has a battery system to ensure a consistent power supply.

Protection relay (Main characteristics: (SIA-C type)

We provide complete power system automation solutions for the oil and gas industry based on the approved equipment and technology for Saudi Aramco.

Features:

• PSA software supports multiple workstations in a server/client network.
• PSA software complies with IEC61850.
• PSA software supports a software utility with the ability to export/import historical waveform data records in COMTRADE format.
• PSA software has a database management component to allow selective removal of any range of records from the database and database files archived on magnetic tape or other off-line storage media.
• PSA software supports standard operating system copy-and-paste functions from table and chart views of historical and event data logs, making the information available to other operating system applications.
