Abstract

The use of slip-ring induction machines for isolated distributed generation is investigated. By varying the effective rotor resistance of a self-excited slip-ring induction generator (SESRIG), the magnitude and frequency of the output voltage can be controlled under variable-speed operation. Analysis of a SESRIG supplying isolated single-phase loads is presented. Practical implementation using a chopper-controlled rotor resistance is discussed. Operation of the slip-ring induction machine as a series-connected synchronous generator (SCSG) is briefly described.
