Simplified model of asynchronous engine for study of the starting modes
There has been described a problem encountered at an attempt of adequately modelling the dynamic modes of functioning of the ship autonomous electric power system during commutation of powerful consumers by the example of asynchronous engines (AE) in MATLAB / Simulink. It is determined that the use of the exact mathematical description of AE in modelling is complicated by bulkiness of the system of differential and algebraic nonlinear equations describing its work, and, as result of this, by long duration of calculations. The way out of this situation is the development of the simplified mathematical model of AE that would allow adequate modelling of the AE connecting and disconnecting processes and work out more effective algorithms of managing these processes. A mathematical model that adequately reflects the physical essence of the AE connecting and disconnecting process is suggested.
