Reduced order dynamic model for variable-speed wind turbine with synchronous generator and full power conversion topology

Wind turbine manufacturers are adapting their equipment to comply with increasingly strict transmission integration requirements. One class of the new turbines being developed is the synchronous machine (either wound field or permanent magnet excited) with full AC/DC/AC power electronic conversion. The topology of the new machines differs considerably from that of more conventional forms of power generation with synchronous generator technology and must be considered when modeling the interaction of the turbines with the transmission system. The focus of this paper is the simulation of the response of a variable-speed wind turbine with a synchronous generator and full power electronics to transmission system disturbances using reduced order models compatible with positive sequence phasor time-domain analysis software (e.g., PSS/E or PSLF). The voltage ride through capability of the wind turbine is investigated and analyzed. The dynamic behavior of the wind turbine under different transient conditions is presented
