• Direct connection from the off-shore HV substation by sea cable to the grid connection point on shore;• Installation of a complete HV substation on sea;• Compensation matching on-shore.
Conventional Connection

Conventional Connection

Key issues: Tap range on platform power transformer Reactive power compensation Short-circuit duty of 150 kV equipment and sea cable TSO requirements Transient phenomena on energizing
Name : Etienne Lemaire CG Systems Division35
NEW & innovative AC grid connection concept (PATENT PENDING)
Voltage regulation taken out of the platform transformer;Voltage regulation by booster transformer on shore;Very limited 150 kV functionality off-shore through soft closer on shore; Reactive power compensation without on-shore equipment, using Mvar of the export cable, MV off shore reactors and WTG STATCON capability.

NEW & innovative AC grid connection concept (PATENT PENDING)
36
• New and innovative concept advantages– increased reliability, by moving
the critical and maintenance intensive elements on-shore
– offshore power transformerwithout voltage regulation, ONAN cooled, designed with a hybrid insulation system and equiped with a on-line monitoring system
– optimal use of WTG (SVC function)– short-circuit duty of 150 kV equipment and sea cable is lowered– less weight on the platform and also lower oil volume’s on the
platform– maintenance (interventions) on the most maintenance intensive
components has been shifted to on-shore (reachable 7/7 and 24/24)

NEW & innovative AC grid connection concept (PATENT PENDING)
37
• New and innovative concept advantages– an integrated concept c/w compensation of the reactive power that
conforms to the grid requirements
Name : Etienne Lemaire CG Systems Division38
NEW & innovative AC grid connection concept (PATENT PENDING)
38
• New and innovative concept advantages
– transient phenomena on energizing effectively mastered through the booster soft closing
– 2 active parts:• Exciting transformer #12• Series transformer # 13
– soft closing resistor # 10

Conclusion
40
More reliable installation and less maintenance
A good alternative to a DC-connection
Proposed technique makes it possible to connect a relatively high amount of wind power with an AC-connection to shore
