  • Control method for a system comprising a frequency converter connected to a power grid
    Patent number: 10749343
    Abstract: A method which is suitable for a system having a frequency converter and a generator, both of which are connected to a power grid, includes obtaining sub-synchronous components of the grid voltage and determining damping current set points according to the sub-synchronous components to compensate for sub-synchronous resonances of the grid. Damping current set points are determined by receiving the sub-synchronous components of the grid voltage and returning damping current set points as outputs. A variable damping gain is adjusted according to the sub-synchronous frequency of the grid, such that the required compensation level can be adapted to the frequency converter for damping sub-synchronous resonance of the grid.

  • Protection system for a power converter connected to a doubly fed induction generator
    Patent number: 9467081
    Abstract: Protection system for a power converter connected to a doubly fed induction generator having a rotor and a stator. The power converter includes a grid-side-converter, a machine-side-converter, a DC link between both converters, a chopper connected to the DC link, and a hardware protection system connected to the rotor of the generator. The protection system includes a first control unit for controlling the hardware protection system depending on the voltage in the DC link, a second control unit for controlling the chopper depending on the DC link voltage, and a third control unit for controlling both converters.
