| Popis: | The problem of the existence of common-mode and exchange power fluctuations when parallel operation of synchronous generators in autonomous electrical systems is considered. The methods of mathematical modeling obtained the amplitude and period of common-mode oscillations in the whole possible range of settings of the object under study. A method has been developed for constructing maps of the dependence of the amplitude and period of common-mode power oscillations on the values of the transfer coefficients and setpoints in terms of the rotation frequency of the speed governors of diesel generators. The use of such cards allows you to apply the method of eliminating exchange power fluctuations, taking into account the possible occurrence of common-mode oscillations. Mapping the settings of the amplitude and the period of the common-mode power oscillations makes it possible to understand the tendency of the amplitude and the period of the common-mode power oscillations to change and to carry out an in-depth analysis of the operation of the autonomous electrotechnical complex. |
