Abstract:
Today, all the world direct towards renewable sources, because it is
considered a safe energy. As a result, now the studies concentrate about
the reliability and continuity of the renewable energy. Though, this
thesis presents a recovery strategy that enables the system of HVDC
transmission systems based on voltage source converter, which transfer
electrical power from the wind turbines to the grid, to ride-through
different positions of AC faults with minimum current and voltage
stresses on the converter switching devices. Issue such as control
strategies for a VSC-HVDC transmission system connecting offshore wind
farms to the power network is discussed. A reduced network model has
been implemented in MATLAB/ SIMULINK to assess control performance
during the fault.
