7 © ABB Group May 1, 2015 | Slide 7 Requirements Examples Design Losses Certification InstallationLife Time Platform DesignSystem / Electrical Design Employer Authorities Grid Code O&M Norms & Standard Accessibility Reliability Availability Communi cation HSE Norms & Standard

8 © ABB Group May 1, 2015 | Slide 8 System Design Overall System Configuration Power rating Redundancy Cable route Seabed conditions Onshore connection No of HV Cables Busbar Design Cable Design Transformer Design Water Depth Fault levels

9 © ABB Group May 1, 2015 | Slide 9 System Design Grid Code – Power Quality  Harmonic Requirements  Harmonic emission  Background emission onshore grid  WTG:s  System resonance Harmonic Filter Design  Type of filter, S-filter, C-filter, etc.  Resistor for increased damping  Resistor => Losses => Heating => Forced Ventilation

10 © ABB Group May 1, 2015 | Slide 10 System Design Grid Code – Reactive Power Design  Static Reactive Power req.  Dynamic response req.  Cable Design  Transformer Design  WTG Capabilities  Shunt banks + WTG:s  Small SVC + WTG:s  Full rated SVC  Statcom  Hybrid solutions

11 © ABB Group May 1, 2015 | Slide 11 Platform Design Considerations  Overall Dimension  Interface  Transport and Installation  Environmental provisions  Diesel generator duty  HSE  Access management Systems  Environmental withstand

12 © ABB Group May 1, 2015 | Slide 12 Take away  Electrical Design - Open design to allow for connection of different WTG technologies  Reactive Power – Compensate locally for optimal design  Platform Design – Learn from Oil & Gas, adapt relevant requirements  Respect HSE
