HVDC Technologies
HVDC Classic 300 – 3000 (6000) MW
Thyristor controlled
Switched Reactive Power Control
Typical design valve building plus switchyard
Mass impregnated cables
HVDC Light 50 -1200 MW
Transistor (IGBT) controlled
Continuous Voltage and Reactive Power Control
Typical design with all equipment (excluding
transformers) in compact building
Extruded cables
120 x 200 m, height 22 m
50 x 120 m, height 11 m
Troll Gas Platform, Norway
Key data
Troll is the biggest gas platform in the
world- production 20-30 MEUR/day
HVDC Light handle all power supply
Mayor environmental advantages and
reduced personnel off shore
In operation since 2005, without failures
2 x 40 MW, 70 km sea cable
HVDC Light Transmission – Voltage Source Converters
Applications
Off shore power supply
Wind power integration
Underground transmission
Ratings
Power range 50-1200 MW
Voltages ± 80, ± 150 and ± 320 kV
Extruded cables with prefabricated joints
OH Lines and HVDC Light possible
