| Abstract |
A wind farm with multiple squirrel cage induction generator (SCIG) controlled by a single voltage sourceconverter (VSC) is presented. This configuration removes the need of individual wind turbine converters.The proposed topology is specially interesting for offshore applications which may require HVDC connection. The set of generators is controlled by adjusting the variable slip to its optimum averagevalue. Power maximization is achieved using a wind farm grid with variable frequency and voltage.A VSC-HVDC transmission system is analyzed and a test system composed of twenty turbines and atransmission system is built. A power reduction technique is implemented to stabilize the system duringAC line faults. Steady state and fault ride-through performance are validated using a Real-TimeDigital-Simulator (RTDS). |
