Motor generator sets are widely used to generate electricity in case of grid failure or to supply part of the demand for commercial and industrial consumers. The vast majority of motor generator sets work with constant speed proportional to the grid frequency or to the frequency that is imposed on the load. As a consequence, the motor operates at a speed that does not always correspond to the speed that provides the lowest fuel consumption and/or lower emissions. Aiming to promote degrees of freedom to optimize the performance of motor generator sets, this dissertation describes a control and supervision method for motor generator sets with variable speed where the internal combustion motor is not directly linked to grid frequency. For this, a method of control and supervision for the converters which are inserted between the generator and the grid is developed in details. Finally, simulation and experimental results are presented to demonstrate the performance of the proposed method.
