This article analyzes changes in efficiency and power factor, as well as various operating modes in the capacitor element excitation method, which is increasingly used in asynchronous generators. In this case, the sinusoidal voltage and frequency produced by the induction generator are within the rated values and different operations are compared. The studies were carried out along with the parameters obtained using the simulation model as well as real experimental verification. The simulation model was built in the Matlab Simulink package, which consisted of a rectifier, filter circuit, IGBT transistors and included a control system. In the real experiment, an asynchronous generator with a low-power squirrel-cage rotor was chosen, and sensors for measuring current and voltage were installed on the experimental stand. As a result of the analysis of transient processes occurring in different operating modes of the generator, it was found that the values of voltage, current and frequency changed from the nominal value. The results were achieved by adjusting the speed through a variable speed drive to obtain the rated speed taking into account the speed supplied to the rotor from the hydraulic turbine. At the end of the study, it was concluded that the induction generator has a number of advantages over other types of generators, including simplicity of design, low cost, and the fact that it does not consume a direct current source.
