Type-3 wind turbine generator model with generic high-level control for electromagnetic transient simulations

Electromagnetic transient (EMT) simulations are instrumental in providing researchers and engineers with detailed data about the dynamic behavior of power grids, necessary for analysis, planning, and risk mitigation. Such simulation studies become even more relevant with the increased number of inverter-based resources integrated into the grid. To achieve reliable simulation results, accurate and accessible models are needed, since existing generic models do not always provide accurate transient response, especially during fast transients. This paper proposes a model for the type-3 wind turbine generator, otherwise known as doubly-fed induction generator (DFIG), that combines the benefits of the generic wind turbine model developed by the Western Electricity Coordinating Council (WECC), with the extra accuracy of a detailed electrical model for the DFIG. WECC models are widely used by planners in their phasor-domain model databases. The proposed WECC-DFIG model is designed to be used in EMT-type software, and due its inheritance of the high-level control system, it can reuse control settings from an existing WECC model without re-tuning. It improves accuracy during transients, such as balanced and unbalanced faults.
