Transient Model Validation of Fixed-Speed Induction Generator Using Wind Farm Measurements

In this paper, an electromagnetic transient model for fixed-speed wind turbines equipped with induction generators is developed and implemented in PSCAD/EMTDC. The model is comprised by: an induction generator, aerodynamic rotor, and a two-mass representation of the shaft system. Model validation is conducted by measurement comparison using recordings obtained from switching operations performed at the Nysted Offshore Wind Farm in Denmark. A sensitivity analysis is performed to determine the impact of different model parameters on the simulated response as compared with measurements. This validated model will be used for assessing induced overvoltage conditions that may arise under switching operations similar to those captured by the measurements used for validation.
