What is a substation in a wind farm?
Substations are critical components of utility-scale offshore wind farms. Substations receive the power produced by wind turbine generators, transmitted by power cables buried in the seabed. Once the power reaches the substation, the electricity is stepped up to a higher voltage and sent onshore via high voltage cables.
What is an offshore substation?
Offshore substations (OSS) are essential components in the growing offshore wind industry. These complex structures collect electricity from wind turbines via array cables, increase the voltage, and transmit it to the onshore grid via export cables.
Are floating wind power substations suitable for deepwater wind farm applications?
Floating offshore wind turbine technology, much of it developed domestically, is rapidly advancing and is in the early implementation phase, while floating substation technology is still at an early development stage. This study presents novel floating wind power substation platform designs for deepwater wind farm applications.
What is the difference between floating wind turbines and floating substations?
Steffen A. Shelley, S.Y. Boo, DJ. Kim, VL Offshore; William H. Luyties, Pacific Sky Productions Floating offshore wind turbine technology, much of it developed domestically, is rapidly advancing and is in the early implementation phase, while floating substation technology is still at an early development stage.
Do floating offshore wind projects need an offshore substation?
Floating offshore wind projects connected to offshore oil and gas facilities may not need an offshore substation, for example, Hywind Tampen.
How is a floating wind substation connected to a shore grid?
Multiple intra-field cables interconnect the turbine platforms and substation, and a single export cable connects the substation to the shore grid as depicted in Fig. 4, where 40 units of 5 MW floating wind platforms are assumed.
