Beschreibung
Zusammenfassung:	A saturation effect-based synchronous machine electromagnetic transient modeling method, system and device. In the method, by predicting a first rotor angular velocity, a first rotor angle, a first current q component, a first current d component, a first flux linkage turning point d component, a first flux linkage turning point q component and flux linkage turning data of a synchronous machine, analysis processing is performed to obtain a corresponding second current q component, second current d component, second rotor angular velocity, second rotor angle, stator flux linkage d component and stator flux linkage q component. Thus, a historical amount and a current amount of a rotational potential of the synchronous machine are avoided, and the precision of a simulation calculation result is improved, the calculation result keeping the calculation efficiency of a dq0 model while achieving the precision of a phase-domain model, such that the method has high simulation precision and high calculation efficiency.
