<p>A field-circuit transient-transient coupling simulation method based on a multi-loop manner comprises the following steps: 1) establishing multi-loop models, such as (1) to (6) in the following, of an electrical machine according to a finite element model of the electrical machine and by using a multi-loop theory; 2) by invoking the finite element model, in each system simulation step length, solving self-inductance parameters and mutual inductance parameters of each winding and a damping loop by using a finite element model of an electromagnetic field of the electrical field, and then returning the parameters to the multi-loop model of the electrical machine, to perform iterative solution on the electrical machine and an external circuit model, so as to implement joint simulation by coupling a finite element multi-loop model during system simulation. The present invention provides a field-circuit transient-transient coupling simulation method based on a multi-loop manner that is effectively applicable to multiple finite element model scenarios and can improve convergence performance.</p> |
