ABB has upgraded exiting HVDC stations to achieve higher efficiencies and better performance.
In order to upgrade older plants ABB can adapt modern systems/equipment to be built into existing plants. There are many reasons fo carrying out technical modernization, such as:
- Reduces maintenance
- Better availability
- Greater reliability
- Increased power
- Reduced losses
- Extended operational life time
- A new generation of technical support
For example, we can replace old relay-based or analogue control equipment with modern digital equipment.
