1. Introduction

• CO2 Reduction – Green Energy

• Megacities – Security of Supply



Electrical Energy …

… is the backbone of our society – today and in the future.

Security of Power Supply – HVDC protected Québec

Blackout: a large Area is out of Supply

HVDC “Classic” HVDC PLUS • Thyristors 8 kV – IDC up to 6.25 kA • Up to 10,000 MW @ 800 kV DC OHL • Up to 11,000 MW @ 1,100 kV DC OHL • MI Cable up to 600 kV

• Transistors (IGBT) up to 4.5 kV – IDC ≤ 1.56 kA / 2 kA • Up to 1,000 MW @ 320 kV

(XLPE Cable) – Half Bridge • Up to 2,000 MW @ 500 kV

(OHL / MI Cable) – Full Bridge • XLPE Cable up to +/- 320 kV DC • Trans Bay Cable, USA: 400 MW • 4 x TenneT Offshore: 576 – 864 MW • INELFE, RTE & REE: 2 x 1,000 MW



Australia: Basslink HVDC “Classic” – a combination of DC cables with OHL is cheaper than cable alone

5. Conclusion

Prospects of AC and DC Smart & Bulk Power Transmission Technologies



HVDC – it makes power flow

• With DC, Overhead Line Losses are typically 30-50% less than with AC

• For Cable Transmission (over 80 km), HVDC is the only Solution

• HVDC can be integrated into the AC System

• HVDC supports AC in Terms of Stability

• DC is a “Firewall” against Cascading
