| Abstract |
The slip ring induction machine (asynchronous machine, ASM) is used for variable speed drives where the operation speed is near the synchronous speed. A high power application is the rotating system tie frequency converter, which is a major power source in the variable frequency railway supply. State of the art is a voltage source DC-link converter at the rotor side of the machine. One of the criteria for the rating of the DC-link converter is the current at the rotor side. This current can be higher than the current carrying capabilities of the semiconductors during transient conditions like line voltage breakdowns. The control strategy to handle line failures e.g. big voltage dips without opening the line circuit breaker and fast regaining of undisturbed operation is described. |
