In this article, a study of transients in autonomous asynchronous generators used in microgenerators is carried out. This article analyzes the transients occurring in an asynchronous generator by starting an asynchronous motor by exciting an asynchronous generator using capacitor elements of reactive power consumption. To start the asynchronous generator, mechanical energy is supplied to the shaft of the asynchronous motor at a speed 5-10% higher than the nominal number of revolutions, after which the asynchronous motor starts working in generator mode and generates electricity. To launch the CASSY Lab program, the electrical parameters of an asynchronous generator were considered, as well as transients occurring in operating modes by digitally transmitting the parameters of the electrical energy generated by the generator. Starting an asynchronous generator with the help of this program, a real experimental test was also carried out to determine the sinusoidal forms of voltage and current in three phases in the yuksiz, load and overload operating modes. In the course of a real experiment, it was concluded that the improvement of transients occurring in the modes of operation of an asynchronous generator, i.e. transients during the transition from a non-loading mode of operation to a mode of operation with a load, depends on the mechanical energy transmitted to the shaft of an asynchronous generator for grinding. |
