Abstract: |
In heavy duty drives in the range
of hundreds kW, like cement and minerals industries, wound rotor induction
motors are used. Important users make use of hundred of such drives, summing
hundreds of MW. This type of motors have technical
capabilities to easily operate at variable speed. Despite this simple
capability, the large amount of losses which occur
at low speeds determine the users to use the facility given by the wound
rotor only for starting. Even so, the losses specific to the additional rotor
resistors are quite important, given the range of power. The paper describes
the existing technologies involved in the variable speed drives based on
wound rotor induction machines. Finally, it proposes a technique for starting
which avoids the use of additional rotor resistors and consequently it
eliminates the corresponding losses. The simulations confirm the viability of
the technique. |
