The only way marine current turbines can be connected into the grid meeting some obvious economical and efficiency requirements is being part of a farm.It is then necessary to study, simulate and understand the interactions between marine current turbines when they are exploited in the form of an array. This book tries to clarify how a turbine interacts with the other devices surrounding it. Real physical small scale models of a horizontal axis marine current turbine were designed to behave as similar as possible to a real machine, and an electrical system was designed for the whole...
