15 New DC Cable Link Neptune RTS, USA Ed Stern, President of Neptune RTS: High-Voltage Direct-Current Transmission will play an increasingly important Role, especially as it becomes necessary to tap Energy Reserves whose Sources are far away from the Point of Consumption Safe and reliable Power Supply for the Mega Cities Blackout Prevention Customer: End User: Location: Project Development: Supplier: Transmission: Power Rating: Transmission Dist.: Neptune RTS Long Island Power Authority (LIPA) New Jersey: Sayreville Long Island: Duffy Avenue NTP-Date: 07/2005 PAC: 07/2007 Consortium Siemens / Prysmian Sea Cable 600/660 MW monopolar 82 km DC Sea Cable 23 km Land Cable PTD H 1 MT/Re

16 Prospects of UHV DC Some Countries will need Bulk Power Transmission Corridors Solutions: 800 kv DC & 1000 kv AC DC: 4-6 GW AC: 6-10 GW Increase of Transmission Distance -and Reduction of Losses PTD H 1 MT/Re

17 Transformer for UHV DC Existing Technology and Know- How can well manage higher DC Voltage Stresses Transformers for 800 kv HVDC System are within existing Manufacturing Capabilities Transportation Limits and Converter Configuration will determine Type and Size R&D in Progress in specific Fields Basically a mechanical Issue Works for 800 kv DC Transformer PTD H 1 MT/Re

18 UHV DC Bushing at Test Lab TU Graz Austria 800 kv DC Bushing in Test Field PTD H 1 MT/Re

19 Conclusions Use of State of the Art HVDC Technologies LTT Thyristors less Electronic and less Power Components: - Increase in Reliability Use of Double & Triple tuned Filters: - Space Savings - Increase in Availability Active VSC Filters for AC & DC: - highest Harmonic Performance Advanced Controls with WIN TDC: - a Standard for Industrial & Utility Applications - Product Life Cycle of more than 25 Years PTD H 1 MT/Re
