Reliability study of two offshore wind farm topologies : Radial and ring connection

• Reliable electrical infrastructure in offshore wind farms (OWF) is a key to maintenance cost minimization. Due to the difficult environment and distance to shore reliability is crucial for the feasibility of the OWF. In this study, two different topologies of OWF designs were investigated and compared. An algorithm was established to estimate reliability and economic profit of the two systems. The two topologies under investigation were the radial and ring system configuration. A radial system has in general less components, but the ring configuration provides redundancy. For the particular case studied, with its assumptions, a threshold of 18 turbines was identified. From this level and above the ring configuration is beneficial.
