  • Decomposition and mitigation of a disturbance being present at an electric connection between an electric power generating system and a power grid
    Patent number: 9071132
    Abstract: A disturbance on an electric signal at an electric connection between an electric power generating system and a power grid is decomposed into a first disturbance with a first strength assigned to the electric power generating system and a second disturbance with a second strength assigned to the power grid. A voltage value of a voltage of the electric signal is measured. A current value of a current of the electric signal is measured. A value of an open circuit voltage of an equivalent voltage source is calculated based on the measured voltage value, the measured current value and a characteristic equivalent impedance of the electric power generating system so that the electric power generating system is in a harmonic model. The strength of the first disturbance is determined based on the calculated value of the open circuit voltage of the equivalent voltage source.

  • Method and arrangement for controlling a wind turbine using oscillation detection
    Patent number: 8823191
    Abstract: A method for controlling a wind turbine is provided. The method includes monitoring an electrical quantity at an output terminal of the wind turbine. The electric quantity has an amplitude and periodically varying with a grid frequency. The method further includes detecting an oscillation of the amplitude and decreasing active power output from the wind turbine at the output terminal depending on the detected oscillation.
