Substation (HV/MV) & grid connection
Varian Energy engineers high- and medium-voltage substations and their grid connection, from station layout and component selection through secondary design to technical support during certification, construction and commissioning.
AI-generatedEngineering, interfaces and documentation as one system
For 10, 20, 30, 110, 220 and 380 kV substations, we treat primary and secondary systems as one coordinated design. Station layout, equipment, cables, protection, metering and control systems are developed around the requirements at the point of connection.
- Engineered for confidence
- Interfaces clearly defined
- Documented for review
Technical scope in detail
The service modules are clearly structured and can be combined to match the project phase, plant configuration and technical requirements.
Station Layout & Primary Design
A coordinated station concept as the basis for detailed engineering.
- Creating the substation layout
- Component sizing and selection
- Cable routes and cable trenches
- Cable sizing
Secondary Design & Control Systems
Coordinated protection, metering and communication.
- Secondary design
- Communication structure for SCADA and control systems
- Protection concepts
- Metering concepts
Grid Connection & Certification
Connecting technical requirements with the required evidence.
- Grid compliance requirements
- Technical coordination of grid connection interfaces
- Support throughout the entire certification process
Construction & Commissioning
Technical support as the station design is delivered.
- Technical support during construction
- Technical support during commissioning
- Coordination of outstanding technical interfaces
