3 Power Conversion - Our core business Electricity into motion Motion into electricity Electricity into electricity Electrical energy transformed into mechanical energy by a motor Compressors Propellers Rolling mills Pumps Mechanical energy transformed into electrical energy by a generator Wind Turbines Turbogenerators Hydropower Wet Renewables Adjusting frequency and current through a converter or an inverter Wind/solar PV Railway substations Pulse power supply Soft Starters Ship propulsion Wind farm Railway substation Transforming energy to optimize customer process is our mission 3

4 Renewables in Power Conversion Onshore wind Wind turbine drive train Power quality Offshore wind Turbine Offshore drive Wind train Wind farm architecture and power quality Solar PV Photovoltaics farms Solar P (>500kW, architecture and power quality) Wet renewables Tidal/current/wave farm architecture and power quality Our offering Wind converters (for doubly fed, full power) Generators (Permanent magnet generators, direct drive, hybrid and standard speed) Solar inverters Power conditioning systems (grid compliance) Power collection and farm level architecture Marinized solutions (Wet) 4

5 Complete solution offering + + Electrical grid Electrical machines Variable speed drives Automation and control Mechanical equipment Continuously advancing technology in critical components Helping to optimize the whole system architecture Mastering interfaces 5

6 HVDC connection Actual project Wind farm project Overall project 600MW farm 100 km distance from shore 150 kvdc transmission line Offshore AC in field collection AC / DC conversion platform Equipment for AC/DC conversion on a platform Basic building block: MV7000 AC transformer platform Includes transformers, switchgears, etc 6

7 Synergies within GE on technology for Offshore/Marine renewable energy Offshore & Subsea Power for GE has synergies with Wind, Wave and Tidal technology - Similarities on power technology, technical requirements, reliability, etc. - Some of the same companies (i.e. Statoil) involved - GE has developed a lot of technology relevant for Renewable industry but... - more shallow water in renewables 7

8 Tidal turbine: Wet renewables - Permanent magnets synchronous machine - Venturi diameter : 16 m - Internal diameter: 3m - Total weight (turbine + base) : 850 T - Electrical rated point : 690 V, 800 A, 28 Hz, m/s

9 Lessons learned Design, manufacturing and tests of full scale system: Tidal farm turbine electrical and control interfaces, DC power generation: H bridge, Serialisation: redundancy, pulses shift MF transformer technology and practical aspects, MF rectifier, immersed in oil, Auxiliary power from shore via DC link Converter marinisation, Sea bed interface without anchoring, Installation sequence, 9
