PSCAD/EMTDC Based Simulation Study on Dynamic Model of Doubly-Fed Variable Speed Wind Turbine

By use of electromagnetic transient simulation software PSCAD/EMTDC and applying vector control principle of induction motor and serial correction of proportion-integral (PI) regulator, a control system model of variable speed wind turbine (VSWT) based on doubly fed induction generator is established. Combining the established model with the existing models in the model library of PSCAD/EMTDC, a dynamic model of VSWT based on doubly fed induction generator is formed. According to operating characteristic the dynamic model of VSWT is verified and its effectiveness is validated by simulation. Simulation results show that this dynamic model of VSWT can meet the technical requirements from wind turbine manufactures and can be used as a new means for the research on working performance of VSWT based on doubly fed induction generator.
