Reactive Power Control Strategies for DFIG-Based Plants

This paper explores and compares the performance of alternative voltage control strategies applied to doubly fed induction generator (DFIG). Different combinations of reactive power control of rotor- and grid-side converters are investigated for voltage-control purposes. Simulations are performed using detailed models built in DIgSILENT PowerFactory in order to illustrate the influence of controllers on transient stability and steady-state operation of the DFIG-based wind plant. This paper also proposes appropriate control strategies for different sets of network operating conditions and topologies. Operational limits, such as current margins and pulse-width modulation limits, are also taken into account.
