The double-fed induction generator wind turbine has recently received a great attention. The steady state performance and response of double fed induction generator (DFIG) based wind turbine are now well understood. This paper presents the analysis of stator and rotor flux linkage dq models operation of DFIG under different faults and at different locations.
An accurate model and reliable detection system of an induction motor is a very important tool for diagnostic and fault detection. This paper deals with modelling of an inter-turn short circuit in stator and rotor windings of an induction machine and the fault detection at start-up. Winding function approach is chosen for the fault modeling and time-frequency analysis is proposed for the detection...
Three equivalent drive train models of a wind turbine generator (WTG) are presented in this paper. The flexibility of the blades bending and the drive train are considered to analyze its transient stability under a three-phase fault. The simulations show that the fifth order lumped-mass model provides too optimistic estimation while the ninth order three-mass model can observe the motion of shaft...
An important aspect of wind power plant (WPP) impact studies is to evaluate short-circuit current (SCC) contribution of the plant into the transmission network under different fault conditions. This information is needed to size the circuit breakers, to establish the proper system protection, and to choose the transient suppressor in the circuits within the WPP. This task can be challenging to protection...
