Abstract: A method for controlling transfer of electrical power in island mode in an arrangement comprising a converter and a load connected to the converter through a filter. The method comprises determining voltage reference components for one or more frequency components of an output voltage of the converter. An effect of a load current is compensated for by forming one or more voltage feedforward terms on the basis of the load current and using the feedforward terms to adjust the voltage reference components. Control reference components for one or more of the frequency components are formed on the basis of the voltage reference components, and a control reference is formed on the basis of the control reference components. The output voltage of the converter is controlled on the basis of the control reference.

Abstract: A method of estimating a rotor angle of a synchronous reluctance motor, where the motor comprises a stator and a rotor. First, a stator flux and a stator current are determined. Two orthogonal stator flux components in a stator reference frame are calculated from the stator flux. Two orthogonal stator current components in the stator reference frame are calculated from the stator current. Two rotor orientation vectors are then calculated using a known rotor direct and quadrature axis inductance components, the stator flux components, and the stator current components. A rotor angle is estimated on the basis of the rotor orientation vectors.
