More Information
Summary: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.
