A variant of a diesel generator power plant consisting of a conventional diesel-generator set and a variable-speed diesel-generator set is considered. A transformer-free topology of the power circuit of the variable-speed diesel-generator set is proposed on the basis of an active voltage rectifier, a mains inverter, and a buffer energy storage device. The block diagram for controlling a diesel-generator power plant is developed. The autonomous and parallel operation modes of the diesel-generator sets are considered. A block diagram of the speed controller on the basis of intelligent controls is proposed for the variable-speed diesel generator set. The simulation model of the diesel-generator power plant is implemented in the MATLAB/Simulink suite. Results of simulation modeling of the power plant's dynamic operational modes under load switching are presented. The variable-speed diesel-generator set is shown to provide energy-efficient operation of the power plant and compliance with the requirements for the quality of generated electricity when the internal combustion engine runs at low energy efficient rotation speeds in the shared load mode.
