Integrated design for optimum performance

Offshore wind connection

Service focuses on generic operation and maintenance

Grid Code focuses on reactive compensation, voltage control , Harmonic performance, fault level

Configuration with our without OFS, distributed vs bulk, AC vs DC, collection grid voltage

Losses minimization focuses on collector network topology and feeder arrangement

Safety focuses on accessibility within substation

Optimization focuses on the selection, sizing and design of equipment (HV, MV, transformer and other auxiliary equipment ).

Responding to key Offshore Wind challenges

Digital Substations

Digital substations Conventional substations

Benefits

Reduced copper cables through fiber optic bus solutions, for

• Reduced risk of corrosion • Reduced risk of damages caused by harsh environmental conditions,

especially salty / humid environments• Reduced weight

Reduced footprint for reduced space, resulting in

• Reduced CAPEX, especially in space-resctricted, e.g. commercial & industrial applications

• Offshore Wind substations

Reduced substation complexity for

• Reduced OPEX and simplified substation maintenance, allowing full focus on Offshore wind generator O&M

Future-proof IEC-61850-8-1/-9-2 support, the very latest industry standard
