Avoiding dangerous overspeed in ultrahighspeed turbine-generator set applied for waste and renewable energy recovery

The paper is concerned with the study of a nonlinear speed control loop of an ultrahighspeed turbine-generator set applied in waste and renewable energy recovery system. The target of the study is to compare two speed control configurations and to select one configuration and its optimum control parameters on the basis of a series of systematic simulation investigations. Large signal transient responses had to be investigated beside the small signal analysis due to the strong nonlinearity of the induction generator.
