  • METHOD AND APPARATUS FOR CONTROLLING A FREQUENCY CONVERTER
    Publication number: 20130176751
    Abstract: An apparatus and method of controlling a frequency converter is provided. First, subsynchronous components in the electrical grid are identified using voltage measurements of the electrical grid. The subsynchronous components of the electrical grid are then used to determine set points for damping currents. These damping currents are then added to current set points calculated by power regulation loops to generate total current set points. Thereafter, the frequency converter is controlled based on the total current set points.

  • COLLECTOR ANTI-WEARING AND LUBRICATION SYSTEM FOR VARIABLE SPEED WIND TURBINE
    Publication number: 20130038061
    Abstract: A variable speed wind turbine having a doubly fed induction generator (DFIG), includes an exciter machine mechanically coupled to the DFIG and a power converter placed between a rotor of the DFIG and the exciter machine. Thus, the power converter is not directly connected to the grid avoiding the introduction of undesired harmonic distortion and achieving a better power quality fed into the utility grid. Moreover, the variable speed wind turbine includes a power control and a pitch regulation.
