Dfig Converter With Active Filter
Abstract: Systems and methods for operating a power system having a doubly fed induction generator are provided. In example implementations, an electrical power system (100) connected to a power grid (190) can include a generator (120) comprising a stator and a rotor, the stator connected to the power grid via a stator power path, and a power converter (130). The power converter (130) can include a line-side converter (134) coupled to the power grid (190) via a converter power path and a rotor-side converter (132) coupled to a rotor bus (124) of the rotor and the line-side converter (134) via a DC link, the rotor-side converter (132) configured to convert a DC power on the DC link to an AC signal for the rotor bus (124). The power system (100) can also include an active filter (250) comprising one or more active controlled components, the active filter (250) being coupled in parallel with the rotor-side converter (132) to reduce harmonics of the electrical power system (100).
