“…Similar principles are used in [8] to [16]. Rotor position detection systems, based in MRAS or PLL methodologies, are presented in [9][10][11][12][13][14][15][16], some working on the rotor reference frame [10][11][12] and others on the stator reference frame [13,14].

“…It was concluded that the best results are obtained when rotor currents are used [12]. In [15,16] the PI control is replaced by a hysteresis controller, but the principles remain the same. Because the rotor current is used for phase comparison, the method is not satisfactory in the case of low load.…”

A sensorless method for the estimation of the rotor position of the wound-rotor induction machine is described in this paper. The method is based on the MRAS methodology and consists in the comparison of two models for the evaluation of the active power transferred across the air gap: the reference model and the adaptive model. The reference model obtains the power transferred across the air gap using directly available and measured stator variables. The adaptive model obtains the same quantity in function of electromotive forces and rotor currents that are measurable on the rotor position, which is under estimation. The method does not need any information about the stator or rotor flux and can be implemented in the rotor or in the stator reference frames with a hysteresis or with a PI controller. The stability analysis gives an unstable region on the rotor current dq plane. Simulation and experimental results show that the method is appropriate for the vector control of the doubly fed induction machine under the stability region.

A sensorless method for the direct estimation of the slip position of the wound-rotor induction machine is introduced, discussed, and experimentally validated in this paper. The slip position is necessary for the implementation of control by flux orientation. The method proposed is based on the phase comparison of an estimated air-gap power vector and the measured rotor currents in a common reference frame. The proposed method can be implemented in the rotor or in the field reference frames with a hysteresis or proportional-integral controller. The method is sensitive to the stator no-load active and reactive powers, but this dependence is not very important. Simulation and experimental results show that the method is appropriate for the vector control of the doubly fed induction machine. Unlike other methods, this method gives acceptable results when the load is small. In addition, it does not need a flux estimator for the implementation of flux orientation.

In this paper, different Model Reference Adaptive System (MRAS) based speed estimation methods are presented for a stand-alone Doubly Fed Induction Generator (DFIG) operating in the Variable Speed Constant Frequency (VSCF) mode. Among different MRAS based speed estimation techniques, stator flux based, rotor current based and reactive power based methods are compared in terms of their speed tracking capability during load and speed transients and also with parameter variation. Simulation results are presented to show the performance of each method.
