Reactive power capability of doubly fed asynchronous generators

Control& Implementation of Fuzzy Based DFIG Wind Power Generators in Unbalanced Microgrids

“…Thus, a control provision is required for the rotor-side converter to mitigate the torque/power pulsations of DFIG. SantosMartin et al in [23] show that the simultaneous elimination of the torque and real power pulsations can not be performed under unbalanced grid voltage condition. Thus, the proposed control scheme herein is designed to compensate the torque and reactive power pulsations as shown in Fig.…”

Doubly-fed Induction Generator Drives for Wind Power Plants

“…With the derived equations for the active and reactive power flow capability diagrams for the DFIG drive can be drawn as it was carried out in Santos-Martin et al (2008) including the contribution of the mains-side inverter and LC-filter. The possibility of distributing the reactive power between stator and rotor allows for the splitting of the magnetising current in stator and rotor reactive current components.…”

Information gap decision theory based OPF with HVDC connected wind farms

“…In order to study the steady state behavior of DFIG-based wind farms properly, it is necessary to model the DFIG's active/reactive power capability curve [33]. In this paper it is modelled based on the assumptions and considerations given in [33], [34].…”

“…In this paper it is modelled based on the assumptions and considerations given in [33], [34]. The following limits are considered: 1) Stator/rotor current limit 2) Steady state stability limit 3) Total Capability limit 4) Wind-Turbine maximum/minimum active power output limit Hence, active and reactive power production limits of DFIGbased wind farm are as follows.…”
