| Abstract |
The paper presents the performances of a DFAM whose stator is connected to the industrial grid and rotor supplied by a three phase voltage source which keeps constant the ratio r = u2 /f2. The steady state characteristics and the dynamic behaviour are investigated to obtain the guidelines for the various possibilities of control. The equations of DFAM are written in terms of space vectors. The dynamic behaviour is investigated by the numerical integration of the equations. The slip-angle characteristic is considered very important for obtaining the domain of slips where work at constant torque is possible. The dynamic performances are poor when the voltage source has no automatic control. The balance of the reactive powers at various values of the ratio r leads to the idea of a control strategy at unity power factor to the industrial grid. |
