“…Power flow in the drive system with DFIM and power converter If power converter (rotor voltage source) allows only unidirectional power flow ( Fig. 1), i. e. from the network to the machine (diode rectifier at the input side instead of the transistor bridge), then the operational area is limited to the supersynchronous speeds [6][7], assuming that the machine operates as a motor (Fig. 2).…”

Doubly-fed induction machine is usually used in variable-speed electric drives, where the rotor speed is in the vicinity of the synchronous speed. Finite-element-method model has been built and several studies, i. e. start up, sudden load change and fan drive, have been performed in order to verify the machine behaviour in supersynchronous motor operation. The simplest form of control (open-loop U/f control) has been used for rotor voltage supply, while the stator was connected directly to the public network. Streszczenie. Maszyna indukcyjna dwustronnie zasilana jest zwykle używana w napędach elektrycznych o zmiennej prędkości, gdzie prędkość wirnika jest zbliżona do prędkości synchronicznej. Opracowano model w oparciu o metodę elementów skończonych. Przeprowadzono doświadczenia, w których zmieniano parametry rozruchu, obciążenie i wentylator w celu sprawdzenia zachowania maszyny w trybie pracy silnika supersynchronicznego. Najprostsza forma sterowania (sterowanie U/f w otwartej pętli) została wykorzystana do zasilania napięciowego wirnika, podczas gdy stojan został podłączony bezpośrednio do sieci publicznej.

“…The doubly fed induction machine (DFIM) working as a generator is getting a lot of attention in the present time [1][2][3], especially in the field of renewable energy applications such as generating the electricity from wind natural sources. In the other side, usage of DFIM as a motor is still limited and few studies have been introduced about it [4][5][6].…”

The paper presents an applicable sensorless model predictive direct torque control (MP DTC) technique for a doubly fed induction machine (DFIM) drive operating in motor mode. An effective sensorless procedure is presented to get a robust drive performance for the desired speed change. The advantage of the proposed sensorless topology is that there is no necessity for estimating the flux, as presented by various searches before. A dSpace 1104 prototyping control board is used to implement experimentally the control procedure. Obtained results prove the validity of prospective control approach in obtaining a high dynamic performance of the DFIM drive for the required speed changes.
