Substation secondary technology

Substation secondary technology

Secondary technology in substations refers to all systems and devices that support the monitoring, control, protection and automation of primary technology (high-voltage switchgear, transformers, etc.) in a substation. At F.Y.K. Group GmbH, we offer the following services in the field of secondary technology for substations.

F.Y.K. Protection- and Network planning GmbH

Specific services provided by FYK Group GmbH include

  • Engineering and planning for the integration of secondary technology in existing and new substations.
  • Supply and installation of protection and control systems.
  • Testing and commissioning of secondary systems in substations.
  • Modernisation and retrofitting of older systems with current technologies and communication standards such as IEC 61850.

Protection systems

Protection relays and protection devices

Installation and programming of protection relays (e.g. overcurrent protection, distance protection, differential protection) that detect faults in the grid and enable targeted disconnection.

Fault analysis

Automatic detection and analysis of grid faults (e.g. short circuit, earth fault) to ensure grid stability and prevent damage.

Setting and parameterising protection devices

To optimally configure protection systems and adapt them to the specific requirements of the network.

Control technology and automation

Telecontrol technology (SCADA systems)

Implementation of SCADA (Supervisory Control and Data Acquisition) to monitor and control the substation remotely. This enables the operator to receive real-time data and control switching operations via a central control centre.

Automated control systems

Automation of switchgear to enable automatic switching operations in the event of faults or load changes, which increases the reliability of the grid.

IEC 61850

Implementation of the IEC 61850 communication standard for data exchange between different secondary systems in the substation.

Measuring and monitoring technology

Instrument transformers (current and voltage transformers)

Installation and calibration of instrument transformers to accurately record current and voltage values in the grid.

Monitoring systems

Installation of monitoring and diagnostic devices to constantly check the condition of the primary technology in order to be able to react to deviations at an early stage (e.g. temperature monitoring, moisture and gas detection in transformers).

Communication and information systems

Communication networks

Setting up networks for communication between different substations and central control centres, e.g. via fibre optics, Ethernet or other protocols.

Data transmission

Secure and fast transmission of measurement and control data to the energy management system (EMS) or the operations management system (DMS).

Cybersecurity

Protection of communication systems against attacks and disruptions to ensure the security of the substation.

Project planning and engineering

Planning and design of secondary technology

Creation of circuit diagrams, protection and control schemes and wiring diagrams for the substation.

Consultancy and project management

Support with the integration of secondary technology into existing substations, including retrofit projects and new alignments.

Simulation and protection calculations

Carrying out grid studies, protection device coordination and simulations to check the behaviour of protection systems in the event of various grid faults.

Commissioning and maintenance

Commissioning

On-site testing and inspection of the secondary system components, including protective relays, control and monitoring systems, to ensure that everything is working properly.

Maintenance and service

Regular inspection and maintenance of the secondary systems to ensure their functionality and reliability.

Fault analysis and troubleshooting

Locating and rectifying faults in the secondary systems to minimize downtime.

Training and support

Staff training

Technical training for operating personnel to ensure the operation, maintenance and troubleshooting of secondary technology.

Technical support

Ongoing support for the maintenance and optimisation of secondary technology in the substation.

The secondary technology in a substation

    is a decisive factor for the safety and efficiency of energy transmission. F.Y.K. Group GmbH offers customized solutions in this area that are tailored to the needs of utility companies and large industrial consumers.
