Abstract :
The paper is concerned with the study of the speed control loop of an ultrahigh speed machine applied in the utilisation of renewables and in recovering waste energy. The rated speed of the machine is 90 000 rpm. The main target is to prevent the overspeed of the machine set by studying with simulation the response of the nonlinear speed control loop by taking into consideration both the mechanical and electrical transients of the turbine-generator set and the effect of the PWM converter connected to the generator.
