Wind turbine model validation based on state interval and error calculation

: In order to simulate and evaluate wind farm low-voltage ride through capability, wind turbine should be modelled and simulated as real-life system operation. In this paper, a validation method based on state interval and error calculation is proposed. The model validation speci- fi ed in domestic and international standards is introduced. The necessity of steady- and transient-state interval de fi nition is analysed through wind turbine transient behaviour research. Meanwhile, allowed tolerances are studied by wind farm simulation and comparison, using wind turbine models with different behaviours. A double-fed induction generator (DFIG) wind turbine model is validated and the results show that the pro-posed method with different tolerance in steady- and transient-state intervals is suitable for wind turbine model validation.
